x402 Deep Audit $0.05 / call
A premium trust report on any x402 endpoint.
GET /v1/x402/audit-proRuns the full x402 audit (challenge validity, schema, discovery surfaces, Bazaar metadata) and adds a live probe for rail coverage (Base and Solana), multi-rail detection, HTTP status, and latency — everything an agent needs to decide whether to trust and buy from an endpoint.
Parameters
url required | x402 paid endpoint to audit |
Example
macOS / Linuxcurl -s "https://quartermaster.surewhynot.app/v1/x402/audit-pro?url=https://x402-endpoints.onrender.com/web/extract"curl.exe -s "https://quartermaster.surewhynot.app/v1/x402/audit-pro?url=https://x402-endpoints.onrender.com/web/extract"Unpaid, these return 402 Payment Required with the payment details in the header (add -i to see them). curl.exe ships with Windows 10+ and works in cmd and both PowerShell versions. To actually pay, use an x402 client (see Connect) or call it as the MCP tool. Cost: $0.05 per call.
FAQ
How is this different from x402 Audit?
Audit checks the endpoint's declared surfaces; Deep Audit also probes it live for rail coverage, multi-rail support, and latency, and returns a pro-tier report.
How do I pay for this endpoint?
Call it with no payment and you receive HTTP 402 with machine-readable payment requirements. Attach a USDC payment on Base with any x402 client (for example @x402/fetch) and retry — the whole loop is two requests. This call costs $0.05 in USDC.
Do I need an account or API key?
No. There are no accounts, logins, or API keys anywhere in Quartermaster. Payment is per call over the x402 protocol; your wallet is your identity.
Can I call this as an MCP tool instead?
Yes. Quartermaster is also an MCP server at /mcp, so any MCP client (Claude Code, Claude.ai, Cursor) can mount this tool. See /connect for setup.
