x402 Bazaar Scout $0.05 / call
A vetted, ranked Bazaar shortlist — not a listing dump.
GET /v1/x402/scoutSearches the Coinbase Bazaar for a capability, then live-probes the top candidates: is each still returning HTTP 402, and how fast? Returns a ranked shortlist with a best-value pick, so an agent buys from something that actually works right now.
Parameters
query required | Capability you're shopping for |
Example
macOS / Linuxcurl -s "https://quartermaster.surewhynot.app/v1/x402/scout?query=web extraction"curl.exe -s "https://quartermaster.surewhynot.app/v1/x402/scout?query=web extraction"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 Discover?
Discover returns raw Bazaar matches; Scout live-probes them for health and latency and ranks the working ones first.
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.
