Endpoint
HEADhttps://chat.sperax.io/api/x402/intel/open-interest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time or near-real-time open interest data for DeFi derivatives markets without committing to a subscription or API key. Ideal for agents that need pay-as-you-go access to DeFi intelligence using USDC micropayments on Base. Prefer over traditional data providers when you want on-chain-native, AI-augmented derivatives analytics with no upfront commitment.
Side effects
- Payment not included or insufficient USDC balance — returns HTTP 402 Payment Required
- Invalid or unsupported asset/market symbol — returns error or empty result
- Network congestion on Base causing payment confirmation delays
- Rate limiting if payment is not properly processed
- HEAD method returns no body — metadata only, no payload data
