How this service works
Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.
Output
A normalized JSON response containing current fee rates and structures for one or more DeFi protocols, sourced from public on-chain data providers with edge caching and multi-source fallback applied.
Example use cases

“Pull the current fee rates across DeFi protocols so I can compare which one is cheapest to swap on right now.”

Endpoint
GEThttps://x402.santyvv.com/api/defi/fees?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need DeFi fee data without setting up an account or managing API keys, especially in agent workflows that support x402 micropayments on Base. Ideal for one-off or low-frequency lookups where subscription overhead is not justified, or when operating in a keyless, wallet-native environment.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Invalid or malformed query parameters — returns 400 Bad Request
- Upstream data provider unavailable and all fallbacks exhausted — returns 503
- Rate or network congestion on Base causing payment confirmation delay — timeout or 504
