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
A JSON object containing an array of yield pool records — each with pool ID, project name, chain, symbol, APY (total, base, reward), TVL in USD, 7-day impermanent loss, stablecoin flag, and exposure type — plus a summary object with average APY, total TVL, and pool count, and a timestamp.
Example use cases
Stablecoin yield comparison for treasury
“Find me stablecoin liquidity pools with at least $10 million TVL — I want to compare APYs across protocols like Aave and Curve so I can decide where to park idle USDC.”
High-yield pool discovery for DeFi bot
“Give me the top 100 DeFi pools by APY, with a minimum TVL of $2 million — I need the base APY, reward APY, and 7-day impermanent loss for each so my bot can rank opportunities.”
Chain-specific yield research
“Pull up the top 200 yield pools right now and include TVL, APY, and which chain each one is on — I'm trying to figure out where the best opportunities are outside of Ethereum.”
Technical details
Endpoint
GEThttps://chat.sperax.io/api/x402/yields?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, cross-protocol DeFi yield pool data (APY, TVL, chain, project) without a long-term API key commitment — ideal for pay-as-you-go agent workflows, one-off yield research, or automated DeFi opportunity scanners that use x402 micropayments on Base. Prefer it over generic DeFiLlama API calls when you want a curated, AI-augmented view with built-in filtering by TVL and a structured summary.
Side effects
- Payment not included or insufficient USDC — returns 402 Payment Required
- limit parameter exceeds 500 — may return validation error or be capped
- minTvl filter too high — returns empty pools array with valid summary
- Network or upstream DeFiLlama data unavailable — may return 503 or stale data
- Invalid parameter types (e.g. string instead of integer for limit) — returns 400 Bad Request
