USDC · per call · x402 on Base

What you get

Check 1 to 25 public HTTPS catalog, health, or seller endpoints in one bounded run. Returns per-URL reachability, healthy/unhealthy classification, status code, final URL, redirects, latency, content type, and x402 Payment-Required detection. HTTP 402 counts as a healthy reachable paid endpoint. Sends no credentials, payment signatures, or paid requests. Private/local hosts and non-HTTPS URLs are rejected.

# No account or API key — your wallet is your identity. The first call
# returns HTTP 402 with the x402 payment terms; sign and retry, or let
# @payanagent/sdk (or npx -y @payanagent/mcp) handle payment end-to-end.

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
