Verifi

Ask a real human to verify a claim. intent: what your agent is trying to do (max 2000 chars). claim: the claim a human should verify (max 4000 chars). agent_id: your wallet address (0x + 40 hex). Signs the x402 payments. callback_url: optional HTTPS endpoint for verify.ready or verify.failed. Use it to avoid an active polling loop; retain verify_id for recovery. payment_signature: optional manual compatibility input. Standard x402-aware MCP clients send the signed payment through request metadata automatically. Returns status "processing" with a verify_id. Prefer callback_url, or poll get_verify at the returned interval until status is "ready" or "failed". If ready, call unlock_verify. Only one active verify per agent_id at a time.

Poll until ready or failed. Honor retry_after_seconds while processing.

Pass gate 2 for a ready chain and return the human result. This gate costs 2.90 USDC. Omit payment_signature first: standard x402-aware MCP clients handle the payment request and retry through MCP metadata automatically. Generic clients can pass the resulting x402 signature manually. Never pass a private key.
