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 fee data for DeFi protocols, sourced from multiple public on-chain data providers. Includes protocol-level fee metrics, aggregated and standardized for consistent comparison across protocols. Response is edge-cached for performance.
Example use cases

“Can you pull the latest fee data across DeFi protocols so I can figure out which ones are cheapest to use for my yield farming strategy?”
Protocol revenue tracking dashboard
“I'm building a dashboard — can you get me the current fee metrics for DeFi protocols so I can track how much revenue each one is generating?”
Research report on DeFi fee trends
“I'm writing a report on DeFi economics. Can you fetch normalized protocol fee data so I can analyze how fees have been structured across major protocols?”

Endpoint
GEThttps://x402.santyvv.com/api/defi/protocol-fees?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need DeFi protocol fee data without wanting to manage API keys or accounts. Ideal for agents that can pay micro-amounts of USDC on Base via x402, want normalized multi-source data in a single call, and benefit from edge caching and fallback resilience. Best when simplicity and keyless access matter more than raw data customization.

- Invalid or malformed query parameters — returns 400 Bad Request
- Upstream public data provider unavailable — may return stale cached data or 503
- Rate limiting from underlying sources may cause delayed or partial responses
