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 HTTP HEAD response headers containing DeFi protocol intelligence metadata for the specified protocol, sourced from SperaxOS AI-powered analytics. The response is gated by a $0.001 USDC micropayment on Base via the x402 payment protocol; wallets with a SIWX agentcash identity may access identity-only tiers for free.
Example use cases
DeFi protocol research for portfolio decisions
“Can you fetch the latest protocol data for Uniswap from SperaxOS? I want to see the DeFi intelligence metrics before I decide where to allocate funds.”
Automated protocol monitoring in agent workflow
“Every hour, pull the SperaxOS protocol data for Curve Finance and alert me if anything significant changes — use my USDC on Base to pay for each request.”
Comparing multiple DeFi protocols
“Get me the SperaxOS protocol intelligence for both Compound and Aave so I can compare their metrics side by side. Pay per request from my Base wallet.”
Technical details
Endpoint
HEADhttps://chat.sperax.io/api/x402/v1/data/protocol?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need AI-powered DeFi protocol intelligence without committing to a subscription API key, and you want to pay only for the requests you make using USDC on Base. It is ideal for agentic workflows that need on-demand protocol data with micropayment billing, or for wallets already enrolled in the agentcash SIWX identity system that can access free identity-tier data.
Side effects
- Payment not included or insufficient USDC balance — returns 402 Payment Required
- Invalid or unrecognized protocol identifier — returns 404 or empty response
- Network issues on Base blockchain during payment settlement — payment may fail or timeout
- Wallet not funded with USDC on Base — request blocked at payment layer
- Rate limiting or protocol not yet indexed by SperaxOS — returns empty or partial data
