Overview

Which MCP server or API does this? Pass ?q=weather forecast and get matches from the official MCP registry (37,000+ servers, CC0) and the APIs.guru OpenAPI directory (2,500+ APIs, CC0), refreshed every hour: how to connect (remote URL or package), description, repository, docs and OpenAPI spec, last-updated date with a flag for entries untouched for a year. Also our own measured status (answering now, 7-day uptime, Arc payment offer, outside payers) for matching Arc agents. Listed is not working: we do not test these servers, and each API has its own terms. A search with no match is answered before payment: nothing is charged.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i https://api.jarvisclaw.ai/v1/marketplace/api/tool-finder

# 2. Pay it (the SDK signs and retries for you)
curl -H "X-PAYMENT: <signed-payload>" https://api.jarvisclaw.ai/v1/marketplace/api/tool-finder
