Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@369 Meter score this gaming hook: 'Dominate the arena or die trying'"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.

# 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_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).
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).
MIT — see LICENSE. The gateway service itself is operated by VeritasWorks;
this repo publishes the adapter and the directory manifests.

Paid MCP tools behind one endpoint. Agents pay per call in USDC on Base via x402.
Pay-per-call MCP tools for agents, settled with x402 (USDC on Base mainnet). 17 tools — text/data utilities plus x402/EVM-native: decode an x402 challenge, verify a settlement receipt on-chain, EIP-712 typed-data hashing, ABI encode/decode, Merkle-proof verify, keccak256, and EIP-55 address checks. No API keys.
Metered MCP tools: free discovery over MCP; per-call execution settled in USDC via x402 v2.
x402 pay-per-call APIs over MCP, settled in USDC on Base for autonomous agents and developers.
