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 on-chain DeFi intelligence for the requested blockchain, including chain-level metrics, analytics, and statistics relevant to decentralized finance activity on that network.
Example use cases
Monitor Base chain DeFi activity
“Get me the current on-chain DeFi stats for the Base network from SperaxOS — I want to see the chain-level metrics right now.”
Compare DeFi metrics across chains
“Fetch the chain data for Ethereum from SperaxOS so I can compare its DeFi activity against Base — go ahead and pay the micropayment.”
AI agent DeFi dashboard data feed
“My agent needs fresh on-chain intelligence for the Base chain from SperaxOS to update my DeFi dashboard — retrieve the latest chain data and pay with USDC.”
Technical details
Endpoint
GEThttps://chat.sperax.io/api/x402/v1/data/chain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-chain DeFi intelligence for a specific blockchain and want to pay per-request with USDC without managing API keys. It is ideal for AI agents that operate on Base and can handle x402 micropayments natively, and when you need lightweight, low-cost access to chain-level DeFi data without a subscription commitment.
Side effects
- Insufficient USDC balance for micropayment — payment fails and request is rejected with 402
- Invalid or unsupported chain identifier — returns error indicating chain not found
- Wallet identity not recognized — SIWX authentication failure for identity-gated endpoints
- Network timeout or chain RPC unavailability — returns 503 or timeout error
- Malformed request parameters — 400 bad request if required chain field is missing
