zero fetch --capability agentservices-defi-yield-comparison-c248d3db
```

Example prompt: Can you compare the current DeFi yield rates across protocols on Base so I can figure out where to park my funds for the best return?

## When to prefer this

Use this endpoint when an agent needs real-time DeFi yield comparisons across multiple protocols on a specific chain, especially when optimizing capital allocation in a DeFi portfolio. Prefer this over manual scraping of individual protocol sites or generic crypto data APIs that don't focus on yield aggregation.

## Known failure modes

- Unsupported or misspelled chain name returns empty or error response
- Stale yield data if underlying DeFi protocols have not recently reported rates
- Payment failure via x402 micropayment results in 402 response and no data returned
- Empty response schema may mean limited structured error messages are surfaced

## How this service works

Paid data APIs for AI agents. Crypto market data, DeFi yields, IP geolocation, dispute resolution, marketing intelligence. Powered by x402 micropayments on Base.

## Output

A structured list of DeFi protocols and their current yield rates (APY/APR) for the specified blockchain chain, enabling direct comparison of returns across lending, liquidity, and staking protocols on that network.
