## 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 saylor-innovations-uniswap-v3-pool-state-ae8e62ae
```

Example prompt: What's the current spot price, tick, and fee tier for the Uniswap V3 WETH/USDC pool at 0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640 on Ethereum?

## When to prefer this

Choose this endpoint when you need live, on-chain Uniswap V3 pool state — especially spot price from slot0, current tick, liquidity, and fee tier — across any of 16 supported EVM chains in a single call. It is ideal for DeFi agents monitoring liquidity positions, checking whether a pool is in-range, or needing token metadata alongside price data, without constructing raw RPC calls yourself.

## Known failure modes

- Invalid or non-existent pool address returns an error or null fields
- Unsupported chain name or chain ID returns an error
- Pool exists but token metadata (symbol, decimals) is unavailable, returning null for those fields
- RPC node timeout or chain congestion may cause delayed or failed reads
- Pool contract does not follow Uniswap V3 interface, causing decoding errors

## How this service works

Uniswap V3-style pool state for 16 EVM chains: spot price from slot0, current tick, in-range liquidity, fee tier and both token symbols.

## Output

A JSON object containing the chain name and chain ID, pool contract address, token0 and token1 details (symbol, address, decimals), current tick, sqrt_price_x96, in-range liquidity, fee tier in basis points, factory address, data source, and a plain-language note summarizing the result.
