What can Funding Rate Arbitrage Scanner API do?

The registry lists Funding Rate Arbitrage Scanner API as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Funding Rate Arbitrage Scanner API?

Does Funding Rate Arbitrage Scanner API need an API key?

Is Funding Rate Arbitrage Scanner API open source?
