How this service works
All-in-one reputable data source for AI agents and developers. Crypto spot/OHLC, derivatives funding rates, open interest, liquidations, forex, commodities, indices, social sentiment, DeFi protocols, and more — 17+ upstream data sources behind a single x402 paywall. Usage: Send requests to any proxied path (e.g. GET /coingecko/api/v3/...). Unauthenticated requests receive a 402 challenge with payment instructions. Include X-PAYMENT header with a valid signature to access data.
Output
A list of funding rates for the specified crypto symbol (e.g. BTC) broken down by exchange, sourced from CoinGlass via the Starchild Relay proxy. Typically includes exchange name and the current annualized or periodic funding rate for each perpetual futures market.
Example use cases
Funding rate arbitrage opportunity scan
“Show me the BTC funding rates across all exchanges — I want to see where the rate is most negative so I can spot a short squeeze setup.”
ETH derivatives sentiment check
“Pull the ETH funding rate breakdown by exchange so I can see whether the market is net long or net short going into the weekend.”
Multi-asset funding rate comparison
“What are the SOL funding rates on each exchange right now? I'm trying to figure out which platform has the most favorable rate before I open a position.”

Endpoint
POSThttps://5108-data-api-proxy.community.iamstarchild.com/coinglass/api/futures/funding-rate/exchange-listWhen to prefer
Use this endpoint when you need cross-exchange funding rate data for a specific crypto asset in a single call, especially if you're already using the Starchild Relay x402 payment infrastructure for other crypto data. Prefer this over direct CoinGlass API access when you want a pay-per-call micropayment model without a monthly subscription, or when you need to combine funding rate data with other Starchild endpoints (spot, OI, liquidations) in a unified workflow.
Side effects
- 402 Payment Required if X-PAYMENT header is missing or invalid — agent must complete x402 payment flow first
- Empty or null result if the symbol is not recognized or has no active futures markets
- Upstream CoinGlass API unavailability causing 502/503 errors
- Invalid symbol format returning an error or empty response
- Rate limiting or quota errors if the payment signature is replayed
