x402 risk API
Let an agent pay for one stop/go diagnostic without creating an account.
Do Not Act exposes paid diagnostic routes for agents that need a small, verifiable check before a larger market, token, wallet or tool-call action. The x402 bridge is read-only and consumes each valid payment once.
Prediction-market example
GET https://donotact.com/x402/v1/dispute/polymarket/580810
The canonical route returns a standard x402 payment challenge with a payment-required header. Agents with an x402 client retry the same URL with PAYMENT-SIGNATURE or x-payment. Custom agents can still pay the exact Polygon stablecoin challenge and retry with X-402-Tx-Hash.
Token-risk example
GET https://donotact.com/x402/v1/preflight/token/{chain}/{address}
Token preflight returns a fail-closed T-code verdict for honeypot/rug-style risk signals when the paid call is verified. The /x402/tx/... alias remains available for agents that can pay on-chain but cannot yet construct a standard x402 payload.
Boundary
The payment unlocks a diagnostic response. Do Not Act never receives private keys, never signs on behalf of a caller, and never executes the trade or token purchase.
