Common questions

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

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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.

Services

REST route	MCP tool	Service	Price/call
`POST /v1/text/analyze`	`text_analyze`	TextIntel — deterministic text analysis (counts, readability, script mix, keywords)	$0.01
`POST /v1/hook/score`	`hook_score`	HookScore — gaming headline/hook scored 0–100 against the 369 team's hook rules	$0.01
`POST /v1/translate/check`	`translate_check`	TranslationCheck — EN↔FA translation QA score 0–100	$0.02
`POST /v1/game/facts`	`game_facts`	GameFacts — live game metadata from RAWG (release, ratings, Metacritic, platforms, genres)	$0.03

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).
