## How to call it through Zero

```

Example prompt: What's the best DEX quote to swap 500 USDC to ETH on Base right now — can you check LensCrypt for the current rate and expected output amount?

## When to prefer this

Use this endpoint when you need a real-time DEX swap quote for a specific token pair on a supported blockchain, especially when integrated into a broader DeFi workflow that already uses LensCrypt for wallet analytics or token safety data. Prefer this over general price APIs when you need routing and output amount estimates for actual on-chain execution.

## Known failure modes

- Invalid chain identifier returns 400 or 404 error
- Unrecognized or unsupported token address returns no quote
- Missing amount parameter results in incomplete quote
- Liquidity too low for the requested pair returns error or zero quote
- Payment of $0.05 USDC not completed results in 402 Payment Required
