## 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 ozmium-uniswap-v3-full-range-lp-add-oz-weth-1-a1392088 -d '<json body>'
```

Example prompt: Generate the Uniswap V3 full-range mint calldata for the OZ/WETH 1% pool so I can add 500 OZ and 0.0004 ETH from my wallet 0xABC...123, with 1% slippage tolerance.

## When to prefer this

Use this endpoint when an AI agent needs ready-to-sign Uniswap V3 calldata for the OZ/WETH 1% pool specifically, and cannot or does not want to rebalance positions — full-range is the safe default that never goes out of range. Prefer this over the Aerodrome route when targeting Uniswap V3 mechanics (concentrated liquidity, NFT position) rather than a vAMM. Choose this over manual SDK construction when the agent needs a single HTTP call that returns broadcast-ready multicall steps including automatic ETH wrapping and excess refund.

## Known failure modes

- Invalid or non-checksummed owner address returns a 4xx error
- OZ or ETH amounts provided as atomic integers instead of human decimal strings cause incorrect calldata
- Amounts too small to satisfy Uniswap V3 minimum liquidity thresholds may return an error
- Slippage percentage set too tight may cause on-chain transaction revert at broadcast time
- Pool not found or misconfigured on the target network returns a server error

## How this service works

Uniswap V3 mint calldata for the OZ/WETH 1% pool at FULL RANGE, bundled multicall([mint, refundETH]) with the ETH side as msg.value so the manager wraps it and refunds any excess. POST /v1/tx/lp/uni/add { owner, ozAmount, ethAmount, slippagePct? }. UNITS: HUMAN DECIMAL STRINGS (e.g. "0.0004" ETH), NOT atomic - same exception as the Aerodrome route. Full range never goes out of range, which is the only safe default for an agent that cannot rebalance.

## Output

Returns an array of transaction steps, each with a `to` address, `data` (calldata hex), and `value` (ETH as msg.value to be sent). The multicall bundles the mint and refundETH calls so any excess ETH is automatically returned. Also includes the target `network` identifier.
