Changing an API key or wallet could attach a new caller to an existing proxy billing the previous identity. The listen-race path also lost authentication-mode metadata. Reuse now checks the full-key fingerprint, gateway, wallet identity and chain in both paths; unverifiable old API proxies require a restart. API mode does not parse a leftover wallet.

Current main also lacked parts of the account service support covered by #338: native API paths, incremental Responses/Messages SSE, music/image-edit polling and account-specific cache controls. Restore those paths while preserving main's newer credit status, request journal and settled-charge header changes (through 5375083). Account fetches retain Request headers, remove payment proofs, reject foreign origins and redirects, and normalize account /v1 base URLs. Queued polling responses are fully consumed, addressing the review's response-body retention concern. Invalid configured keys fail instead of choosing another payer.

README/skills clarify registration, credit top-ups, restarting after credential changes, wallet-only settlement fees, actual Predexon payloads and Surf HTTP usage/pricing.

Validation: 1,061 local unit tests plus 5 lifecycle integration tests pass; independent lockfile install, build/dist smoke, typecheck, lint, formatting and brand-number checks pass. Added account/wallet/key/gateway/chain reuse tests including listen races; 43 service parity cases cover auth, errors, SSE, cache isolation and music polling. No live transfers or production activity/ledger reconciliation were performed in this pass.

This is a focused follow-up on current main to the review issues on #338, which remains open separately. Account passthrough retains main's x-blockrun-cost-usd charge accounting, verified by regression tests. Image generation, image editing, music and video also read the settled charge from the completed poll response instead of the initial submission or absent x402 hook. Dashboard activity remains authoritative where the gateway provides no settled cost.

📝 Walkthrough

Walkthrough

The proxy now supports API-key account passthrough, strict credential validation, asynchronous job polling, streaming responses, settled-cost billing, and payment-identity checks when reusing existing proxies. Documentation and tests describe the updated account-credit and wallet payment flows.

Changes

API-key payment routing

Layer / File(s) Summary
API-key validation and polling
src/api-key.ts, src/api-key.test.ts
API-key files and environment values reject invalid or unreadable credentials. API base URLs and request headers are validated. pollApiKeyJob handles asynchronous completion, gateway retries, failure states, and aborts.
Account passthrough and async services
src/proxy.ts, src/proxy.api-key-services.test.ts, skills/imagegen/SKILL.md, skills/predexon/SKILL.md, skills/surf/SKILL.md
API-key mode forwards native /v1/* paths, preserves response metadata, streams bodies, polls media jobs, and records settled gateway costs. Skill documentation describes the updated response and payment flows.
Proxy identity and reuse validation
src/proxy.ts, src/proxy.credential-reuse.test.ts, README.md
Health data includes API-key fingerprints and gateways. Existing-proxy reuse rejects authentication, credential, gateway, wallet, chain, and Solana-address mismatches. README instructions describe restart and credential-clearing requirements.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 9f259

API-key media jobs now record the completed gateway charge for image edits and audio generation, avoiding zero-cost usage records. No current merge-blocking risk remains.

Use the settled cost from the completed poll response.

When pollApiKeyJob returns a completed response, use gatewaySettledCostUsd(upstream) before paymentStore.getStore()?.amountUsd in both image-edit and audio usage logging. pollApiKeyJob preserves the completed response headers, but API-key requests do not run the x402 payment hook, so both paths can log 0 instead of x-blockrun-cost-usd. Add regression coverage for both paths with the header on the completed poll response and an assertion on logUsage.

Reuse compared wallet-vs-key and never which key, under a comment claiming to
"never reuse across credentials". A second `clawrouter login` on a port already
serving another key attached silently: the new process printed the new key and
reported "listening", while every request kept being charged to the previous
account.

Reproduced on the shipped 0.12.272 before fixing — a proxy started with key A
went on answering /health as key A while a second process configured for key B
reported success on the same port. Cross-account billing with a success message
in front of it.

The masked label /health already publishes is enough to tell two keys apart, so
reuse now requires it to match. A proxy that reports no label cannot be verified
and is refused rather than assumed to match: an unverifiable credential on a
money path is not a match. Same-key reuse is unchanged, which is the case the
guard exists to keep working.

The four tests fail against the previous code — verified by reverting proxy.ts
and re-running, since a guard that passes both ways guards nothing. One of them
re-asserts the original wallet-vs-key refusal, which the new comparison joins
rather than replaces.

Found and reported by @KillerQueen-Z in #343. That PR also re-applies parts of
#338, which landed separately as bef780f, so it conflicts and needs a rebase;
this takes only the credential-binding half, which is live and billing the wrong
account today.

Took the credential-binding half of this and landed it as 0554d1b — thank you, this was a real one and it was live.

I reproduced it on the shipped 0.12.272 before fixing: a proxy started with key A kept answering /health as key A, while a second process configured for key B printed the new key and reported listening on the same port. Every request went on billing A. Cross-account billing behind a success message, which is about the worst failure shape available here.

What landed: reuse now requires the masked label /health publishes to match, and a proxy that reports no label is refused rather than assumed to match — an unverifiable credential on a money path is not a match. Same-key reuse is untouched. Four tests, verified to fail against the previous code by reverting proxy.ts and re-running, since a guard that passes both ways guards nothing. One of them re-asserts the original wallet-vs-key refusal, so the new comparison joins it rather than replacing it. You are credited as co-author on the commit.

The rest of this PR now conflicts and needs a rebase. main moved a lot while it was open:

  • feat: complete account API service forwarding and polling #338 landed as bef780f, so the account-service parity work here is largely already in — native /v1 passthrough, origin pinning, redirect refusal, no-store, async 202 polling, and fail-closed key resolution. Re-applying it would revert newer work rather than restore it.
  • v0.12.271 and v0.12.272 shipped on top: the request-id journal, the settled-charge header, the 152x cost fix, the media $0 fix, clawrouter reconcile, and the credit warning.

Three things to know before rebasing, because they are places where this PR and current main disagree on purpose:

  1. The account passthrough keeps its logUsage write. The early return in feat: complete account API service forwarding and polling #338 said account billing is authoritative in the portal. That was true when written; x-blockrun-cost-usd now exists and the journal consumes it, so dropping the row would re-hide Surf/Exa/prediction-market spend from /stats — the bug 0.12.271 fixed.
  2. no-store is keyed on the credential, not the route. The partner prefixes are matched earlier and are equally account-authenticated.
  3. Empty BLOCKRUN_API_KEY is treated as unset, not fatal. FOO="" is the ordinary way to clear a variable in CI; present-but-malformed stays fatal.

If you rebase onto main and drop what has already landed, I expect this reduces to a fairly small diff. Happy to review it promptly.

Proxy reuse compared wallet-vs-key but never which key, under a comment claiming
to "never reuse across credentials". Reproduced on the published 0.12.272: a
proxy started with key A kept answering /health as key A while a second process
configured for key B printed the new key and reported "listening" on the same
port, and every request went on billing A.

So `clawrouter login` with a second key told the user it worked, then charged
the previous account. Reuse is now bound to the credential.

Found by @KillerQueen-Z in #343.

…ps stop being silent

Four fixes, all on paths where the wrong answer costs money.

spend policy (#329): `SpendControl` was reached only through the x402 pre-sign
hook, so on the API-key rail none of it ran — `daily=5` written on a wallet went
on reading like a $5/day cap after `clawrouter login` while the real ceiling was
the account balance. The amount windows are denominated in USD and say nothing
about how money moves, so they now hold on both rails from the same
spending.json, enforced at the key rail's only equivalent choke point: the fetch
every paid call goes through. It records what the gateway actually CHARGED when
it says so, charges nothing for a request the gateway rejected, and bills an
async media job once rather than once per status poll. The counterparty lists
stay wallet-only — they presuppose a payee, a network and an on-chain asset.

plugin-id migration (#319): the gate asked for `walletKey`/`routing` under
`plugins.entries.clawrouter`, and OpenClaw's installer writes `{enabled: true}`
and nothing else. So the ordinary pre-rename install was never migrated, and a
pre-rename OPT-OUT was inverted — bundled router off, BlockRun on by installer
default, proxy up on a machine where it was off. Now also accepts the on-disk
proof `clawrouter setup` already uses.

reuse race: v0.12.273 bound reuse to the credential on the pre-listen probe
only. The EADDRINUSE branch compared the payment chain alone, so an API-key
caller landing on a Base wallet proxy reused it and got a handle claiming
`authMode: "api-key"` while every request spent USDC. Both paths share one
validator now.

wallet precedence (#315): Core outranking a funded legacy wallet.key moved which
wallet pays, silently. Core still wins — preferring legacy makes Desktop fund
one address while the proxy spends another. The silence was the bug: startup now
names both addresses and the line that keeps paying from the old one. Same for a
chain override from ~/.blockrun/.chain.

Closes #329, #319, #315. Supersedes #343 (@KillerQueen-Z), whose remaining
finding — the unvalidated listen race — is the third fix here.

Superseded. main already carries the origin pin, redirect refusal, header stripping by pattern, fatal-on-malformed key resolution, normalizeApiKeyBase, pollApiKeyJob and the key-fingerprint reuse guard — landed as #338/bef997c and 0554d1b, and this branch conflicts with them.

The one finding here that main did NOT have is real and is now fixed: the EADDRINUSE reuse path checked the payment chain and nothing else, so an API-key caller racing onto a wallet proxy reused it and got a handle reporting authMode: "api-key" while every request spent USDC — and its truthiness test on the reported wallet dropped API-key proxies, which publish an empty one. Both reuse paths run one validator now.

Shipped in v0.12.274 (1d9d51f), credited to you in the CHANGELOG.
