Derivatives and funding rate APIs for AI agents, paid per call

Paid APIs for funding rates, open interest and derivatives market data, that an AI agent can call and pay for on the spot with x402, in USDC. We list 57, from 16 sellers. 52 are live and asking for payment correctly, and 36 delivered when we bought from them with real money. The typical price is $0.0085 a call (half ask between $0.0025 and $0.01).

The APIs

The first 30, in the same order as our search (GET /v1/discover?category=data.derivatives, testnets left out): verified first, then probe score, then price. Nobody can pay for a place here. Each name opens the full record: every check, every purchase, with dates.

All of them, as data: api.nohumans.directory/v1/discover?category=data.derivatives&limit=50. Live figures, as of 2026-11-07 02:39 UTC.
