feat(cost): Cloudflare as a cost source, read with a pasted API token - #2541
Cloudflare is a cost source on /cost. "Add source" lists it, and picking it asks for an API token with the Billing: Read permission on one account. The token is checked with Cloudflare, stored sealed, and the account's daily usage charges (by product and priced metric) plus its paid subscriptions' fees are synced. The token can be replaced and the source removed from its row.
Backend
One generic table, cost_connections (one sealed credential per org and provider), with one secret slot bound to org and provider, a reseal target and the org purge entry. This is the only migration, and the next provider that connects with a pasted credential reuses it without one.
CostConnectionStore seals and upserts (refusing a credential of another account), removes, loads for a pull, and resets a held source on replace. reconcileCostConnectionSources keeps cost_sources in step for each provider in COST_CONNECTION_PROVIDERS.
Cloudflare is a thin user of both: a small billing client (plain HttpClient, explicit decoding), a normalizer, an adapter and PUT / DELETE /internal/cost/cloudflare, audited, behind the cloudCost flag and the integrations:manage grant.
A token is saved only if it reads exactly one account, that account has usage-based billing data, one usage read works, and it visibly reads nothing beyond billing (see below). A replacement must read the same account.
Sync profile: from the first day of the eleventh month back through yesterday. Requests are free, so the source counts none.
The token is kept least privileged
The dialog's link opens Cloudflare's Create Token form from a template, with the name filled in and Billing: Read as its one permission. The help text says what is left there: pick the one account, set an expiry if wanted, create, paste.
A token cannot be asked what it may do (listing its own policies needs a permission a billing token lacks). So after the other checks pass, a save asks Cloudflare for four things a billing token must not see: account members, the Workers subdomain, audit logs and zones. A 200 on the first three, or a zone list with something in it, is access, and the token is refused naming what was found. A 401 or 403 is the answer wanted. Any other answer fails the save as a check that could not be made.
A fifth probe, the Workers scripts list, was dropped: a preview trace showed it taking 1.8 s where the others took under 0.2 s, with the whole save waiting for it, and the Workers subdomain already tells a Workers-reading token apart. That change is covered by the fake only, since the test tokens no longer exist.
The probes run side by side on a save and a replace only, never in a sync pull.
What this does not prove: a token with some other extra permission none of the four touches still passes. It catches the common over-broad tokens, not every one.
OAuth is the intended home for this source. Cloudflare offers OAuth clients no billing scope today, so it is a pasted token for now. docs/cloud-cost-plan.md records that and the steps to move it once a scope exists.
Two facts of the usage API that shape the pull (both checked live):
to is exclusive, and a billing period's rows come back only when the period starts inside the asked range. Every request therefore asks from 31 days before its first day to the day after its last, and keeps only its own days.
A range is 90 days at most, so a window is read in pieces of 55 days.
Web
The pasted-credential step of the dialog is one form described by data (credential-sources.ts): list row, field, help link, titles, row action, confirm and toasts, and the save and remove commands. The existing key-based provider moved onto it with its wording and behaviour unchanged, and Cloudflare is a second entry.
The first-sync wait, the empty state and the free-requests note name providers from the provider table.
Marks follow the page's one rule for every provider (a name first, then the org's only platform, else the kind's glyph), with Cloudflare's product names among the known ones.
A Cloudflare product wears the Cloudflare mark in the table, the legend, the chips and the filter rail. A Cloudflare account reads as "Cloudflare ": the source's accountName is filled from the account label stored with the token. Its rows filter and drill down like the others.
Each row action's accessible name says whose source it acts on ("Remove Cloudflare source"), since two rows can offer the same action.
Decisions worth a look
Subscription fees are a purchase row on the day each billing period starts, stepped back from the current period by its frequency (a week, a month, three months) at today's price. Cloudflare reports only the current period, so a price change is not visible for past months. Trial, failed and expired subscriptions get no fee.
A subscription made on the 29th to 31st keeps its first period's fee, on the day it was made. Without created_date only the current period's fee is stored. A priced plan that cannot be placed on a day is counted on the pull's span (maple.cost.cloudflare.fees_skipped).
An answer must say success: true and hold all it lists. A 200 with an empty result and no success, a subscription list read short of its count, or a usage answer that starts to page fails the pull instead of storing empty days or missing fees.
Known limit: a fee is known only while its subscription is listed. If a cancelled one leaves the list, the next re-pull of the open months stores those days without it. Documented in docs/cloud-cost-plan.md.
A token that lists several accounts is refused instead of picking one.
How it was verified
Backend: 316 tests pass over services/cost (every provider's) and the cost reads, on the tree merged with main (normalizer on recorded-shape rows, adapter and connection service against a fake HTTP server, sync plan profile, reconcile in the sync service, the account name in the sources read). Migration parity passes.
Web: 75 scene, mark and fixture tests pass, including the unchanged flows of the existing key-based provider.
The new errors carry a public body: a test shows a refused token's reason reaching the page and a failed save's own text staying server-side.
Typecheck: domain, db, backend, api, web. Lint with the CI config on every touched file. gen:anticipated-errors, ios:openapi and ui:patterns checks are current.
Live, read-only, against a real pay-as-you-go account, from a script that printed only pass or fail and row counts: a closed month's billed and list totals match the raw rows to the cent, per day as well. A four day head window returns all four days including yesterday. A four month window read in pieces matches month by month reads with no doubled row. The oldest month the profile asks for is served whole. Subscriptions decode and produce fee rows, the listing is read whole against its own count, and no charged plan is left unplaced. No day and metric came in two rows or two units. A wrong token is 403 on the account list and 401 on billing.
Live, least privilege, with two real tokens for one account, through the real save path against a test database, printing pass or fail only: the billing-only token is accepted and stored, the broader one (billing plus Workers scripts and account settings) is refused naming account members and Workers scripts and nothing is stored, and as a replacement it is refused with the stored token unchanged.
Preview-tested twice with real tokens on a pay-as-you-go account (comments below): add, first sync, replace, remove and the audit log, with October equal to the provider's own API to the cent; then the least-privilege check, where a token that can read more than billing was refused on add and on replace and a Billing: Read token was accepted.
Not run on a preview: the final head, which is those commits merged with main and one probe fewer. Both are covered by tests against the fake server.
An org's Cloudflare charges are read from the billable usage API: one row per
day, product and priced metric, in the account's billing currency. Paid
subscriptions add their fee on the day each billing period starts, stepped back
month by month from the current period at today's price.
The token is saved through PUT /internal/cost/cloudflare. It is checked with
Cloudflare first: it must read exactly one account, that account must have
usage-based billing data, and one usage read must succeed. A replacement token
must read the same account, and makes a failing source due again.
The credential lives in a new generic table, cost_connections, one row per org
and provider, with one secret slot bound to the org and the provider. A shared
store seals, upserts, removes and loads it, and one reconcile keeps
cost_sources in step for every provider listed in COST_CONNECTION_PROVIDERS, so
the next provider read with a pasted credential needs no migration. OpenRouter
keeps its own table.
Two facts of the usage API shape the pull. Its `to` date is exclusive, and a
billing period's rows come back only when the period starts inside the asked
range. So each request asks from 31 days before its first day to the day after
its last, in pieces of 55 days to stay under the 90 day cap, and keeps only its
own days. The sync profile serves from the eleventh month back to yesterday.
"Add source" lists Cloudflare. Picking it asks for an API token with the
Billing: Read permission on one account, with a link to where tokens are made.
A refused token stays in the dialog with the reason under the field. The source's
row offers Replace token, which keeps the source and its history, and Remove.
The pasted-credential step is one form described by data. Each provider added
this way is an entry in credential-sources.ts: what its list row, form, row
action, confirm and toasts say, and the commands that save and remove it.
OpenRouter moved onto it with its wording and behaviour unchanged, and the page's
messages name the provider they are about.
The first-sync wait names Cloudflare beside AWS as bringing in months, the empty
state mentions it, and the cost lab has Cloudflare cost, a source and a state for
each dialog.
Backend. A subscription in trial, failed or expired gets no fee row, since its
listed price was not charged. A subscription list longer than the pages Maple
reads fails the pull instead of under-counting. The usage read takes a window
and adds the billing period's lead and the exclusive end itself, so the save
check and the pull share one rule, and the failure's kind is put on the span in
one place. The store maps its own load failures for an adapter. The test fake
serves a year like the real API: the range before the oldest month reaches past
it and is answered with the older days left out.
Web. The credential messages and fields are named for a credential, not a key.
The first-sync sentence and the free-requests note take the provider names from
the provider table, so a second four-week provider reads right. The remove
dialog has no provider until it opens.
Docs say what a new pasted-credential provider adds beyond its literal, and name
the limit on fees of a subscription that leaves Cloudflare's list.

…erved year
The test for the oldest month passed with the fake's one year limit removed: the
only day the limit dropped was outside the pulled window. The window now holds
the oldest served day, in a billing period that started before it, and the day
before it must be absent.
A subscription list longer than Maple reads now says so on the span, with the
page count: its error is made outside the shared call, which annotates the rest.

Include supported weekly and quarterly subscription fees.
Cloudflare permits weekly and quarterly subscription frequencies. For either value, starts is [], so even a paid period starting inside the pull window produces no fee row. Add period handling for these frequencies, or establish an explicit product rule that excludes them. (developers.cloudflare.com)

Do not count subscriptions awaiting payment as paid fees.
A positive-price subscription in AwaitingPayment passes this exclusion list. toSubscriptionRows then records its price as a billed purchase, although the state does not confirm payment. Check the charge state before emitting a fee; do not treat every state other than Trial, Failed, and Expired as paid. Cloudflare lists AwaitingPayment separately from Paid.

…lists
A 200 with success false and an empty result decoded as an answer: read as no
rows, it would store every day of the window as empty. Every envelope now
requires success true and fails as an answer Maple cannot read.
The subscription listing took its page count from total_pages alone, which the
published response does not list: without it only the first page was read. The
count now falls back to total_count over the page size, and a list read short of
its count, or a full page that says nothing of its paging, fails the pull. The
usage answer has no paging today; one that lists more rows than it returns fails
too.
…d non-monthly plans
A subscription made on the 29th to 31st has later period starts clamped to
shorter months, so stepping back from the current one landed days before it was
made and its first period's fee was dropped. That fee now goes on the day it was
made.
Without created_date, which the published response does not list, a monthly
plan got a fee on every period start in the window, months before it may have
existed. Only the current period's fee is stored then.
Weekly and quarterly plans step by their own period. A priced plan Maple cannot
place on a day is counted on the pull's span as fees_skipped.
Two usage rows of one day and metric are still one cost row, since the
warehouse reads them by that key, but only quantities in the row's own unit add
up.
With two sources in the list, two buttons read "Remove" to a screen reader. Each
action's accessible name now says whose source it acts on: "Remove Cloudflare
source", "Replace OpenRouter key", "Manage AWS connection".
Keeps the Cost page rework (#2548) as it landed and re-applies the provider on
top: the provider mark reads an entry without a tint, the lab's facet read
leaves out removed sources like its other reads, and the empty state names
Cloudflare beside the reworked sentence.
On the review's critical finding (credential draft written to a span attribute), checked end to end:
The flagged line builds the password input's DOM attributes. It writes nothing to a span.
The value does travel as the save command's argument (apiToken), and the web tracer records command arguments as maple.foldkit.arg.<name>. Its default policy (packages/effect-sdk/src/foldkit/args.ts) exports only arguments whose name ends in Id, booleans and nulls. Every other value is written as [redacted].
Confirmed on a real preview span of the same flow for OpenRouter (SaveOpenRouterCostKey): maple.foldkit.arg.apiKey: [redacted]. apiToken falls under the same rule.
So the token does not reach telemetry. I will add this PR's own save span to the preview evidence once the preview deploys.
…orked Cost page
A Cloudflare product (Workers, R2, D1, the plan fees and so on) wore the AWS
mark, since every service that is not a model slug was taken for an AWS one. It
now wears Cloudflare's, also beside an AWS source, and a product Maple has no
name for does too when the org has no AWS source that could bill it.
A Cloudflare account reads as "Cloudflare" with its id beside it, by the rule
OpenRouter's follows: the id means nothing to a reader. Its rows filter and
drill down like the others, which the scene test now runs for an account, a
provider and a product.
The cost lab has a state filtered to Cloudflare.

The stored token should read billing and nothing else. A token cannot be asked
what it may do, since listing its own policies needs a permission a billing
token lacks. So once the existing checks pass, a save asks Cloudflare for five
things a billing token must not see: account members, the Workers subdomain,
audit logs, zones and Workers scripts.
The first three are read off the status: a 200 is access. Zones and scripts
answer a billing token with an empty list, so only a list with something in it
counts. A 401 or 403 is the answer wanted and fails no span. Any other answer
fails the save as a check that could not be made, storing nothing.
The refusal names what was found, so the person knows which permission to drop.
The probes run side by side, on a save and a replace only, never in a sync pull.
A token with some other extra permission none of them touches still passes: this
catches the common over-broad tokens, not every one.
The dialog linked to the plain API tokens page and left the permissions to the
reader. It now opens Cloudflare's Create Token form from a template, with the
name filled in and Billing: Read as its one permission. The help text says what
is left there: pick the one account, set an expiry if wanted, create and paste.

Preview test of the least-privilege check (head 02e07d5f1f, app-pr-2541.maple.dev)
Run by a separate agent with two real tokens for one pay-as-you-go account: one with only Billing: Read, one that can also read Workers scripts and account settings. The source was removed at the end.
Flow
Result
The dialog lists AWS, OpenRouter, Cloudflare and GitHub; the note reads "OpenRouter, Cloudflare, and GitHub requests are free."

The Billing: Read token: accepted in 3.4 s, first sync 6 min 49 s after the add, Cloudflare's mark on its rows, in the rail

Console and requests: only the expected 400s
pass
The refusal, word for word: "This token can do more than read billing: it can also read account members, Workers scripts, audit logs, and zones. Create one with only the Billing: Read permission."
(The last line of the help in this screenshot was reworded after the run, in 239f6ebe8e: it no longer says the token is checked to read "nothing more".)
Traces (pr-2541)
Accepted save: 3.10 s in the API. Accounts 229 ms, usage info 510 ms, one usage read 421 ms, then the five probes side by side: members, Workers subdomain and audit logs each answer 403 in 125 to 159 ms, zones 164 ms, and the Workers scripts list 1.80 s, which is what the save waits for.
Refused save (broader token): 3.20 s, every probe answers 200, nothing is written.
No error issue from either. The three 403s of an accepted save are recorded on their outbound spans, as any 4xx is.
Follow-up from the traces: the Workers scripts list is the slowest probe and says nothing the Workers subdomain probe does not (the broader token passed both). Dropping it takes the save back to about 1.5 s. Going in with the next commit.

A preview trace of an accepted save showed the scripts list taking 1.8 s where
every other probe took under 0.2 s, and the whole save waited for it. The Workers
subdomain probe already answers 200 for a token that can read Workers, so the
list told nothing more. Four probes remain: account members, the Workers
subdomain, audit logs and the zones list.
Covered by the fake only: the test tokens no longer exist.
Brings in the Vercel cost source (#2542). Main is the reference for what the
providers share, and Cloudflare is fitted into it:
- Marks: main's rule (a name first, then the org's only platform, else a glyph)
with Cloudflare's product names added to the known ones. My own mark rule and
its region helper are gone.
- Account label: a Cloudflare source now carries `accountName`, filled from the
account label stored with its token, so the page reads "Cloudflare <account
name>" where it showed the 32 character id.
- Row actions: main's naming, with the account when an org has two sources of a
provider. A pasted credential's Replace and Remove go through it.
- Dialog: main's rows, footnote, GitHub and Vercel steps as they are. The pasted
credential step stays one form described by data, used for both providers.
- Removal, the first-sync table, the empty state and the lab follow main, with
Cloudflare added beside the others.
… as a rejected token, not reported as an outage
Cloudflare answers 400 (invalid Authorization header) for a short or malformed token on the account listing. The save mapped that to its could-not-check error, a 503.
Final-head check: the preview of #2544, which is this branch with PlanetScale on top, ran the dialog with all six providers, the Cloudflare form, its billing-read link and a made-up token refusal, all passing. It found one defect here, fixed in a9725467a1: a short or malformed token (x, cfut_other) answered 503 instead of a refusal, because Cloudflare answers 400 to text that is not shaped like a token. The save now refuses it as a rejected token; test added.
🟢 Confidence 10/10 · safe to merge. Sealing, org scoping, upsert guard and pagination are pinned by service tests; the least-privilege probes are exercised only against the fake. no findings · tests covered · risk high · 4/4 new units observable
Adds Cloudflare as a cost source read with a pasted API token: a sealed cost_connections row, a PUT/DELETE /internal/cost/cloudflare route behind integrations:manage, a billing client and normalizer, and a dialog driven by credential-sources.ts. Safe to merge. The two open VcsWebhookEnqueueFailure issues pointing at http-graph.ts are untouched: this change only registers a handler there.
CostConnectionStore seals one credential per org and provider, refusing another account's
CloudflareCostConnectionService checks a token, refuses excess permissions, then stores it
CloudflareCostProvider pulls usage in 55-day pieces and places subscription fees
The cost dialog's credential step is one data-driven form for OpenRouter and Cloudflare

What changed
Cloudflare is a cost source on
/cost. "Add source" lists it, and picking it asks for an API token with the Billing: Read permission on one account. The token is checked with Cloudflare, stored sealed, and the account's daily usage charges (by product and priced metric) plus its paid subscriptions' fees are synced. The token can be replaced and the source removed from its row.Backend
cost_connections(one sealed credential per org and provider), with one secret slot bound to org and provider, a reseal target and the org purge entry. This is the only migration, and the next provider that connects with a pasted credential reuses it without one.CostConnectionStoreseals and upserts (refusing a credential of another account), removes, loads for a pull, and resets a held source on replace.reconcileCostConnectionSourceskeepscost_sourcesin step for each provider inCOST_CONNECTION_PROVIDERS.HttpClient, explicit decoding), a normalizer, an adapter andPUT/DELETE /internal/cost/cloudflare, audited, behind thecloudCostflag and theintegrations:managegrant.The token is kept least privileged
