## 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 uniswap-v3-order-book-depth-api-0a05ab72
```

Example prompt: What's the current order book depth and liquidity for the Uniswap V3 pool at 0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640 on Ethereum — show me the token pair, fee tier, and current price?

## When to prefer this

Use this endpoint when you need on-chain Uniswap V3 liquidity and order book depth data for a specific pool on Base or Ethereum without managing your own RPC node or API keys. It is ideal for pre-trade analysis, slippage estimation, and liquidity monitoring. Prefer this over raw RPC calls when you want structured, analyzed output including token metadata and fee tier, and when paying per-call via USDC on Base is acceptable.

## Known failure modes

- Invalid or non-existent pool address returns an error or empty depth object
- Unsupported chain name causes a bad request response
- Pool with very low liquidity may return minimal or zero depth data
- Network congestion on Base or Ethereum may cause delayed or stale data
- Malformed pool address format (missing 0x prefix) may result in validation error

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object containing the pool address, chain, depth data object, token0 and token1 details, fee tier (integer), total liquidity, current price, and an analyzedAt timestamp indicating when the analysis was performed.
