x402 payment flow (one round-trip)

  1. GET /tools/hash?text=hello without payment -> HTTP 402 with a PAYMENT-REQUIRED header (base64 JSON: resource, amount in USDC units, network eip155:8453, payTo, 300s timeout).
  2. Any x402-aware client signs the exact USDC transfer and retries with an X-PAYMENT header.
  3. 200 + result. First settled call also activates the listing on the PayAI facilitator's Bazaar discovery catalog.

Heads-up: the API is behind Cloudflare. Python's default Python-urllib User-Agent is blocked (403 error 1010). Any real UA works (requests, httpx, curl, axios pass as-is). Details in SKILL.md.

MCP server

  • Hosted: https://pitchpilot-mcp.pitchpilot-agents.workers.dev/mcp - Streamable HTTP, 13 tools, x402 v2 payment settled in-band. Health: /health, card: /.well-known/mcp/server-card.json.
  • This repo (mcp_server.py, Dockerfile): zero-dependency stdio server, Python 3 stdlib only. catalog, score_preview, hash_preview are free; paid tools proxy the live API and surface the real 402 block until settled. See SERVER.md. Registered in the Official MCP Registry as io.github.unnamedaiagent/pitchpilot-agent-tools.

Agent integration

  • Skill for Claude Code / any SKILL.md-aware agent: see SKILL.md (indexed on skills.sh).
  • Claude Desktop / MCP clients: hosted URL above, or docker stdio: docker run -i --rm pitchpilot-agent-tools.

Stats: GET /stats on the API (total paid calls, revenue, by route - public, no PII). Pricing may be adjusted upward; /openapi.json is always live.
