Payment flow

Without payment, a configured route returns HTTP 402 with the official V2 base64 PAYMENT-REQUIRED header. Parse using the official x402 client, approve exact native USDC authorization on eip155:8453, and retry with PAYMENT-SIGNATURE. Successful verification runs the job; settlement follows successful execution. The final response contains PAYMENT-RESPONSE. Failed jobs are not settled. Check a receipt rather than assuming a timeout means payment failed. Consumed authorizations cannot execute again.

Unconfigured receiving address, paused tools, full capacity or unavailable facilitator return HTTP 503 before payment. A payment signature does not bypass the URL safety policy. Current facilitator: https://v2.facilitator.mogami.tech. Seller: 0x9484a00CD18221612A212ADD61161D2d6eef278F. Prices in /v1/tools are live and owner-configurable. Input/output schemas and x402 terms are in OpenAPI; machine documentation is free.

Evidence and limits

HTTP(S) ports 80/443 and globally routable addresses only. Five redirects, twenty same-origin link checks, 6 simultaneous browser jobs, 10 admitted jobs with immediate overflow rejection and no waiting queue, thirty-second total tool deadline. These are configurable operating limits, not permanent ceilings. Screenshot evidence: GET /evidence/{screenshot_evidence_id}, at most 24 hours. Treat the random evidence ID as a bearer capability.

PASS means only that the implemented checks found no listed issue; ISSUE records concrete findings; REVIEW means limited or inconclusive evidence. No legal, accessibility, uptime or page-quality guarantees are made.
