Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

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.

}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.

}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.
