How this service works
Pay-per-call UK company, property and crypto market data for AI agents via x402. Official sources, no signup, no API keys, failed calls never charged.
Output
A JSON object containing the asset pair, data source (Binance Futures), mark price (float), funding rate details (current rate, bias indicating whether longs or shorts pay, annualized percentage, next funding time in ISO 8601), and open interest in both base asset units and USD notional value.
Example use cases
Funding rate arbitrage signal check
“Check the current BTC-USD perp funding rate — I need to know if longs are paying shorts and what the annualized rate is so I can decide whether to do a cash-and-carry trade.”
Open interest market sentiment analysis
“How much open interest is there in BTC perpetual futures right now in both BTC terms and USD notional? I'm trying to gauge overall market exposure before a big news event.”
Automated derivatives monitoring alert
“Pull the latest ETH-USD derivatives data for me — I want the mark price, funding rate, and when the next funding settlement hits so I can time my position entry.”

Endpoint
GEThttps://api.trustedinformation.site/api/crypto/derivativesWhen to prefer
Choose this endpoint when you need real-time crypto derivatives data — specifically mark price, funding rate, and open interest — for perpetual futures pairs, sourced directly from Binance Futures without requiring signup or API keys. It is ideal for AI agents needing pay-per-call access to derivatives sentiment signals (funding bias, annualized rates) with guaranteed no-charge on failed calls. Prefer this over generic crypto spot price endpoints when derivatives-specific metrics like funding rate or open interest are required.
Side effects
- Missing or invalid 'pair' query parameter returns an error — must be formatted as e.g. BTC-USD or ETH-USD
- Unsupported or unlisted trading pair may return no data or an error
- Binance Futures API unavailability may cause upstream data failure
- Payment failure via x402 results in no charge and no data returned
- Malformed request (wrong HTTP method) returns 4xx error
