## 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 vextorium-uniswap-v3-pool-state-on-base-aa150178 -d '<json body>'
```

Example prompt: What's the current spot price and active liquidity for the WETH/USDC pool on Uniswap v3 on Base? Check all fee tiers.

## When to prefer this

Use this endpoint when you need real-time Uniswap v3 pool state specifically on the Base network, including pool addresses, spot prices, ticks, and reserves for a given token pair. Prefer this over generic price APIs when you need on-chain liquidity depth, active tick, or per-fee-tier breakdown rather than just a price quote.

## Known failure modes

- Unknown or unsupported token symbols return null pool data
- No pool exists for the requested fee tier — returns empty or null entry
- Invalid Base token address causes request failure
- Network connectivity issues to Base RPC may result in stale or error response
- Unsupported fee tier percentage (not 0.01, 0.05, 0.3, or 1) may yield no results

## How this service works

Uniswap v3 pool state on Base for a token pair: pool address per fee tier, spot price, tick, active liquidity and token reserves.

## Output

Returns an array of pool objects per fee tier, each containing: pool contract address, fee tier percentage, token0 and token1 symbols/addresses, spot price (e.g. WETH in USDC), current tick, active liquidity amount, and token reserves. Also includes the DEX name (Uniswap) and network (Base).
