asyncio.run(main())

A bare request without parameters returns the HTTP 402 payment challenge (x402 v2 in the PAYMENT-REQUIRED header, v1 in the body). Invalid input gets a 400 before any payment.

Billing policy

Failed calls are never charged. Failed calls are never charged: the payment is verified first, the request runs, and the payment is settled only if it succeeded. Errors (4xx/5xx) are not settled, and invalid input is rejected before any payment or free call.

Uptime and latency

Independent monitoring of this endpoint: 402index service page (health, 30-day uptime, p50 latency).
