Shortest buyer proof
Start on the Wallet Action Preflight API URL. It is the live buyer-safe path at 0.002 USDC on Base and should show the expected 402 -> paid retry -> 200 flow.
Easy Integration
The shortest live buyer path today is the hosted Wallet Action Preflight API at https://x402.bankr.bot/0xc04d0d464752a58b046105b45089d579eaf54036/bankr-preflight for 0.002 USDC on Base. This playground remains useful when a buyer or partner also wants to validate the broader TXRISK direct routes from the public site.
Hosted First
Start on the Wallet Action Preflight API URL. It is the live buyer-safe path at 0.002 USDC on Base and should show the expected 402 -> paid retry -> 200 flow.
Use this browser playground after the hosted proof when you need to inspect the broader direct TXRISK APIs, payload fields, and response bodies on txrisk.xyz.
Run Request
If you are forwarding this to a listing or integration partner, send /partner-evaluator.html first so they have the route inventory, hosted Bankr proof path, discovery links, and MCP metadata alongside this playground.
If the buyer needs help reading the final body, send /action-authorization-response-fields.html. It now leads with the hosted Wallet Action Preflight API, then explains the shipped meaning of decision, policy.reasons, operator.step, and billing with exact fallback examples.
This direct-route playground supports POST /v1/wallet/risk-quickstart, POST /v1/wallet/risk-snapshot, POST /v1/webhook/verify, and POST /v1/lead/qualify, and POST /v1/action/authorize, and POST /v1/account/recovery-authorize with endpoint-specific fields, policy templates, and validation.
