How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns AI-powered DeFi intelligence data for the requested coin/token, including market metrics, on-chain analytics, and token-level insights. As a HEAD request, response metadata and headers confirm data availability and payment status; full data payload would be returned on a corresponding GET.
Example use cases
DeFi token research for trading
“Get me the SperaxOS coin intelligence data for USDC so I can see all the on-chain analytics and metrics before I make a trade — pay the micro fee automatically.”
Automated portfolio monitoring
“Check the SperaxOS DeFi data for each token in my portfolio — BTC, ETH, and SOL — so I can see updated AI-powered metrics for each one.”
Comparing DeFi token metrics
“Fetch the SperaxOS coin data for Arbitrum so I can compare its DeFi intelligence metrics against what I already have for Optimism.”
Technical details
Endpoint
HEADhttps://chat.sperax.io/api/x402/v1/data/coin?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need per-request, keyless DeFi coin intelligence with USDC micropayments on Base via x402 — ideal for agents that don't want to manage API subscriptions and want AI-enriched on-chain token analytics from SperaxOS rather than raw exchange data.
Side effects
- Insufficient USDC balance on Base — payment fails, 402 returned with payment instructions
- Invalid or unrecognized coin identifier — 404 or empty result
- Network congestion on Base causing payment confirmation delay
- Rate limiting if payment not settled in time
- HEAD method returns no body — data must be fetched via GET after confirming payment
