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 structured DeFi intelligence data about the specified smart contract, including contract properties, metadata, and AI-powered on-chain analytics sourced from SperaxOS. The response is delivered after a micro-payment of $0.001 USDC on Base is processed via the x402 protocol.
Example use cases
DeFi protocol contract audit
“Get me the SperaxOS contract intelligence for the Uniswap V3 pool contract at 0x1d42064Fc4Beb5F8aAF85F4617AE8b3b5B8Ee22 on Base — I need its properties and any metadata available.”
Token contract due diligence
“Before I invest, can you fetch the contract data from SperaxOS for the USDC contract on Base so I can review its on-chain details?”
DeFi agent portfolio monitoring
“Check SperaxOS for contract details on 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base — I want to know what properties and DeFi intelligence are available for this asset.”
Technical details
Endpoint
GEThttps://chat.sperax.io/api/x402/v1/data/contract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need AI-powered DeFi intelligence about a specific smart contract without managing API keys, and when you are operating on Base and can pay micro-amounts of USDC per request. It is ideal for autonomous agents that need on-demand contract lookups with minimal setup overhead.
Side effects
- Payment failure if wallet lacks sufficient USDC on Base
- Invalid or unrecognized contract address returns empty or error response
- Network/chain mismatch causes no data found
- Rate limiting or payment processing delays under high load
- Unsupported contract type may return partial data
