Technical details
Endpoint
GEThttps://api.foursec.xyz/funding-rate/history/%7Bsymbol%7DWhen to prefer
Choose this endpoint when you need historical (not just current) funding rate data aggregated across multiple DEXes for a specific crypto symbol, and you want pay-per-request pricing via crypto (USDC on Base) rather than a subscription model. Ideal for AI agents, DeFi analytics tools, or trading bots that need on-demand historical funding rate lookups without committing to a monthly API subscription.
Side effects
- Invalid or unsupported symbol returns an error or empty history array
- Missing symbol path parameter causes a 400 or 404 error
- Insufficient USDC balance or failed x402 payment results in a 402 Payment Required response
- Rate limiting or quota exhaustion may return a 429 error
- Network timeouts for slow DEX data aggregation
