What it does

This x402-payable endpoint queries Binance futures markets to identify contracts with positive funding rates exceeding a configurable threshold. It is designed for traders and agents looking to discover funding rate arbitrage opportunities — where a trader can go long on the spot market and short the perpetual future to capture the funding rate spread.

The endpoint accepts a POST request with a JSON body containing an optional `min_funding_rate` parameter (per-interval threshold, defaulting to 0.0003) and a `debug` flag. Payment is handled via the x402 protocol on the Base network using USDC, with a maximum cost of 1000 units (likely 0.001 USDC given 6-decimal USDC). The endpoint has a maximum timeout of 120 seconds.

The service is hosted on Heurist Mesh, a platform that exposes various AI agents and tools as payable API endpoints. Documentation on the Heurist Mesh site is sparse — the /docs, /api, /pricing, and /README paths all return 404. The endpoint itself is live and returns a valid 402 challenge with a well-defined output schema, but response format details are not documented and must be inferred from usage.
