Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/lending/ratesWhen to prefer
Use this endpoint when you need to rate-shop lending yields across multiple DeFi protocols (Aave, Compound, Morpho, Spark) for a specific asset, especially when you want TVL alongside APY to gauge safety and depth. Prefer this over manually querying individual protocol APIs.
Side effects
- Unknown asset symbol returns empty results or error
- Unsupported chain filter returns no results
- Rate-limit or upstream protocol data unavailable returns partial or error response
- Payment failure (insufficient USDC) blocks the request
- Malformed request body returns 400 validation error
