GET /hello

live

Test endpoint for verifying x402 payment integration end to end. Returns a static greeting in the Agent Tollbooth standard response envelope. Not a data product — use it to smoke-test your x402 client for $0.001 before calling our compliance endpoints.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
