## How to call it through Zero

```sh
zero fetch --capability x402-silverbackdefi-app-d4d8ce05
```

Example prompt: Can you analyze the health of the WETH/USDC liquidity pool on Base chain and give me a health score? Use the token symbols WETH and USDC.

## When to prefer this

Use this endpoint when you need to evaluate the health and liquidity quality of a specific pool on the Base chain before executing a swap or investment, especially when you have a token pair (symbols or addresses) or a direct pool address and want a structured health score rather than just a price quote.

## Known failure modes

- Pool address not found on Base chain — returns error or empty result
- Invalid token address format — malformed 0x address causes validation failure
- Token pair has no existing pool on Base — no pool found error
- Both poolId and token pair omitted — ambiguous or missing input error
- Rate limit or payment failure — 402 response if payment not processed
