Tools
| Tool | Description | Behaviour |
|---|---|---|
| audit_x402_endpoint | Technical audit for API developers launching or debugging x402. Returns deeper read-only evidence of payment configuration, schemas, redirects, CORS, cache behavior, OpenAPI, llms.txt, agent metadata, and x402 discovery consistency. Requires an explicitly authorized x402 purchase; does not test settlement, paid delivery, or actual marketplace indexing. | Read-only |
| inspect_x402_endpoint | Free endpoint check for API developers launching or debugging x402. Inspect your live payment challenge and caller-selected comparison policy without sending payment credentials. ALLOW and BLOCK are policy decisions, not launch certification; a price-limit BLOCK does not establish a broken integration. Buyer-side inspection remains available. | Read-only |
| order_x402_remediation | Diagnostic report for API developers launching or debugging x402. An explicitly authorized x402 purchase creates a durable order for asynchronous findings, evidence, and prioritized fix recommendations in JSON/Markdown. The receipt is not the completed report. No implementation, human consultation, target payment, deployment, or guaranteed marketplace indexing. | Changes data |
