369 Meter — pay-per-call APIs for agents (x402)

Four pay-per-call APIs for agents, one rail: x402 (v1, "exact" scheme, USDC on Base), settling directly to the publisher's wallet. No accounts, no API keys, no checkout — call a route, get an HTTP 402 with payment requirements, pay, get the resource.

Live gateway: https://369yz.pythonanywhere.com/meter/ Health (free): https://369yz.pythonanywhere.com/meter/health PayTo (Base): 0xA0A1ff293EF2FF051121674c8eAAd69570b25e6c Facilitator: payai-public · every 402 declares the Bazaar discovery extension.

How to pay (x402)

# 1. Call without payment -> HTTP 402 + x402 payment requirements
curl -s -X POST https://369yz.pythonanywhere.com/meter/v1/text/analyze \
  -H 'Content-Type: application/json' -d '{"text":"your text"}'

# 2. Sign an EIP-3009 USDC authorization for the amount in
#    accepts[0].maxAmountRequired and retry with the X-PAYMENT header.
#    The resource is served only after the facilitator confirms settlement.

MCP

mcp_adapter.py (this repo, stdlib-only Python) exposes the same four services as MCP tools for directory discovery:

  • stdio: python3 mcp_adapter.py
  • streamable HTTP: mount application in any WSGI server (POST JSON-RPC).

tools/list and initialize are free. Because an MCP transport cannot carry an X-PAYMENT header, tools/call performs the real gateway call and returns the gateway's live 402 payment requirements as an MCP error result — it never serves an unpaid resource. Pay over the x402 rail on the REST route above.

Directory manifests in this repo: server.json (Official MCP Registry, name io.github.369369yz-collab/meter369), glama.json (Glama claim), openapi.json (the REST API spec, prices verified against the live 402s).

Also listed via

  • api.market — the same REST API (openapi.json); api.market auto-generates an MCP endpoint for listed APIs.
  • PayAPI Market — x402 directory (listed 2026-10-25; a $0.02 USDC canary payment from their verification has landed on-chain).
