Get one agent-payment launch blocker fixed or re-checked.

Send one public manifest, OpenAPI file, registry PR, or direct paid endpoint. I will map the no-payment surface, isolate the failing launch control, and either return the patch order or work on a small authorized fix.

Scopes

Choose the smallest paid step that resolves the blocker.

Private re-check

$49

One URL, PR, manifest, OpenAPI file, or endpoint. Output: concise private route map, current pass/fail state, commands used, and the next patch item.

Pay $49

Launch review

$149

One launch surface across multiple routes. Output: spend map, CORS/cache/resource/replay findings, metadata notes, receipt gaps, and ranked fix order.

Pay $149

Fix sprint

$299

Small authorized implementation pass for one blocker: browser-readable 402s, resource echo, cache headers, discovery docs, idempotency notes, or registry proof.

fit

This is for builders who already have a real x402 or agent-payment surface.

run free check

good fit

Registry PR before merge

A pay-skills, Coinbase x402, or public directory PR needs clean launch evidence before maintainers and users trust it.

good fit

Browser-agent blocker

The route returns a 402, but browser clients cannot read the challenge or send the required payment header through preflight.

good fit

Resource and receipt mismatch

The challenge price, resource URL, network, payee, receipt, or retry behavior is ambiguous enough to break an agent buyer.

not fit

Unowned targets

No private testing, exploit work, payment signing, wallet use, or probing beyond public no-payment surfaces without owner authorization.

proof

Recent public reviews have already produced fixes.

The paid sprint exists because the free review loop is working: builders are patching CORS, resource binding, documentation, discovery, and payment-route behavior after no-payment checks.

Cryptorefills checkout

A live demo blocker was diagnosed without payment headers, re-authored by the maintainer, and landed on master with credit.

fixed

Sentinel reputation API

The builder patched browser payment headers and HTTPS resource binding; a fresh pass confirmed the P1 findings were fixed.

field note

x402 CORS fixes

The implementation guide maps OPTIONS preflight, actual 402 CORS, exposed payment headers, middleware order, and resource echo.
