# Ozmium Aerodrome Remove Liquidity Calldata

> Ozmium Aerodrome Remove Liquidity Calldata is a paid API for AI agents from ozmium.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Generates calldata to remove liquidity from an Aerodrome vAMM OZ/USDC pool, optionally prepending an LP-token approve step.

## 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-aerodrome-remove-liquidity-calldata-60d82dad -d '<json body>'
```

Example prompt: Build me the calldata to remove 5000000 atomic LP units of my Aerodrome OZ/USDC position — my wallet is 0xAbc...123, include the LP token approve step for pool 0xDef...456, and use 1% slippage.

## When to prefer this

Use this endpoint when an AI agent needs to programmatically exit an Aerodrome vAMM OZ/USDC LP position on Base and requires ready-to-sign calldata rather than constructing the ABI encoding manually. It is ideal when you also need the LP-token approve prepended in a single atomic calldata bundle. Prefer this over generic DEX exit tools when the position is specifically in Aerodrome's vAMM and the OZ/USDC pair.

## Known failure modes

- Insufficient liquidity amount — LP amount exceeds balance held by owner
- Missing required owner field — returns 400 validation error
- Slippage too tight — minOz or minUsdc values conflict with pool reserves, causing revert on-chain
- Invalid pool address — unrecognized or non-Aerodrome pool returns error
- Payment failure — x402 USDC payment not attached or insufficient, returns 402

## How this service works

Aerodrome removeLiquidity calldata. POST /v1/tx/lp/aero/remove { owner, liquidity, pool?, minOz?, minUsdc?, slippagePct? }. Pass `pool` to have the LP-token approve step prepended; liquidity is the atomic LP amount to burn.

## Output

An ordered array of transaction steps, each containing a `to` address, `data` hex string (calldata), and `value` (ETH), plus a `network` identifier — ready to sign and broadcast to Base. If `pool` is supplied, the first step is the LP-token ERC-20 approve, followed by the removeLiquidity call.
