Call → 402 → sign → result.

Send a POST with JSON. The unpaid response is HTTP402 with a PAYMENT-REQUIRED header and exact payment terms. An x402 v2 client signs the native-USDC authorization, then retries with PAYMENT-SIGNATURE. Inspect PAYMENT-RESPONSE and X-Settlement-Confirmation after the result.

A failed computation is not settled. An uncertain settlement requires reconciliation; do not create a second authorization to blindly retry it. Wallet keys belong in your client's protected environment.

Use the OpenAPI document for each input schema. CSV and JSON validation errors are useful structured results; DNS/email checks describe domain records, not mailbox ownership or guaranteed delivery.

Request bodies and user files are not retained. Operational records contain status, timing and wallet pseudonyms. These tools provide observed technical results; they do not claim independent market demand, investment returns, mailbox validity or a measured uptime SLA.
