> ChainRay DeFi Compare is a paid API for AI agents from chainray.online, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Compares DeFi protocols and analytics across blockchain networks to surface rates, liquidity, and yield data side-by-side

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability chainray-defi-compare-ef276de1
```

Example prompt: Can you compare the top DeFi protocols on Base for me — things like yields, liquidity, and key metrics — so I can figure out where to put my funds?

## When to prefer this

Use this endpoint when an agent needs to compare multiple DeFi protocols on a specific chain simultaneously rather than querying each protocol individually. Ideal for yield optimization, liquidity analysis, or helping users decide where to allocate assets on-chain.

## Known failure modes

- Unsupported chain name returns an error or empty result
- Network congestion may cause stale data
- Missing required 'chain' query param may return default chain or error
- Endpoint may return limited data for newer or less-liquid chains

## How this service works

The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.

## Output

A structured comparison of DeFi protocols on the specified blockchain network, including metrics like APY/yield rates, liquidity depths, and protocol-level analytics for side-by-side evaluation
