Agent402 Direct x402 HTTP Resources is published by [agent402.dev](https://apis.io/providers/agent402-dev/) on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include x402, Website Audits, Technical SEO, URL Evidence, and x402 Endpoint Audit. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, and a getting-started guide.

Eight x402-priced and four free direct HTTP resources on agent402.dev, described by one OpenAPI 3.1 contract (info.version 1.7.0, 12 operations, 14 schemas): the 5.00 USDC AI Discovery Site Audit with its free eligibility check, sample, methodology and frozen case study; the 1.00 USDC Verified URL Evidence Snapshot; a 0.05 USDC website preflight; a 0.01 USDC x402 endpoint health check and a 5.99 USDC x402 launch audit; a 0.01 USDC deterministic task-day planner; and two 5.99 USDC ZIP downloads. Every paid route answers an unpaid request with HTTP 402 and a PAYMENT-REQUIRED challenge (exact scheme, USDC on eip155:8453, 300-second window) and is paid by retrying the identical request with PAYMENT-SIGNATURE; every report carries a stable id and a SHA-256 digest of itself.
