How this service works
Paid API endpoints for prices, weather, FX, news, gas, dominance, fear/greed, ATH, and more
Output
Returns yield/interest rate data for DeFi protocols, including APY or APR figures. When a protocol name is provided, results are filtered to that specific protocol; otherwise, yields across multiple protocols are returned.
Example use cases
Compare DeFi lending yields
“Show me the current yield rates across all DeFi lending protocols so I can decide where to park my stablecoins.”
Check yields for specific protocol
“What's the current APY on Aave right now? Fetch the latest yield data just for that protocol.”
Monitor best yield opportunities
“Pull the latest DeFi yield rates for all protocols so I can see which one is offering the best returns today.”
Technical details
Endpoint
GEThttps://x402-api-production-bd43.up.railway.app/yields?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time DeFi yield or interest rate data and are willing to pay a small per-call micropayment via x402. Prefer this over free alternatives when you need reliable, on-demand yield data with optional protocol filtering in an agent-native payment flow.
Side effects
- Invalid or unrecognized protocol name returns empty results or an error
- Payment of 0.005 USDC required per call — failure to pay returns 402 status
- Endpoint may return stale data if upstream data sources are delayed
- Network or server errors on the Railway deployment may cause 5xx responses
