LivePOSTBase USDC

0.015 USDC per call

x402 V2 exact payment on Base mainnet (eip155:8453) using USDC. The HTTP 402 challenge confirms the exact requirements before an authorized payment.

POST https://signalharness.ai/api/agent/services/polygon_contract_creation_analyze/invoke

Copyable unpaid request

This schema-valid request returns the canonical HTTP 402 challenge without executing the service. A payment-capable client validates the challenge, signs only with prior authority and budget, and retries the identical body.
