## What it does

This skill covers the Uniswap LP API, a service that builds transactions for you. You hand it position parameters; it reads current pool state, works out the amount of the second token, and returns an unsigned transaction. Signing and broadcasting stay in your app. The API holds no keys and moves no funds.

The skill documents the endpoints `/lp/check_approval`, `/lp/create`, `/lp/create_classic`, `/lp/increase`, `/lp/decrease`, `/lp/claim_fees` and `/lp/pool_info`, plus a capability table for V2, V3 and V4 and rules for validating input. One rule stands out: before any transaction that spends gas or moves tokens, the agent must show a summary and get an explicit yes through AskUserQuestion.

Write endpoints want an `x-api-key` header. Keys come from the Uniswap Developer Platform dashboard and belong in an environment variable. Note the host: liquidity lives at `https://liquidity.api.uniswap.org`, not the swap trading API, so keep the base URL as one constant. V2 fees cannot be claimed on their own — they sit inside the LP token value and surface on `/lp/decrease`, and `/lp/claim_fees` with `protocol: "V2"` fails validation.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Uniswap/uniswap-ai --skill lp-integration -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/lp-integration/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/lp-integration/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Uniswap/uniswap-ai --skill lp-integration -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/lp-integration/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Uniswap/uniswap-ai --skill lp-integration -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/lp-integration/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Uniswap/uniswap-ai lp-integration
```

2. **Manually: put the files in place**
- File: `.github/skills/lp-integration/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Uniswap/uniswap-ai --skill lp-integration -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Uniswap/uniswap-ai --path packages/plugins/uniswap-trading/skills/lp-integration
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/lp-integration/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Uniswap/uniswap-ai --skill lp-integration -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Uniswap/uniswap-ai/tree/HEAD/packages/plugins/uniswap-trading/skills/lp-integration/SKILL.md

## When to use it
- create a Uniswap liquidity position from a backend or bot
- add liquidity to an existing position over the API
- remove part of a position and collect accrued fees
- run approval checks before touching a position
- debug EIP-712 permit and transaction-building errors

## Example prompts
- Build a `/lp/create` call for a V3 ETH/USDC position on Arbitrum
- Check the token approval and then create the position through the LP API
- Why does `/lp/claim_fees` with `protocol: "V2"` fail validation?

description: Integrate Uniswap liquidity provisioning (LP) into applications via the LP REST API. Use when the user says "LP API", "liquidity provisioning API", "provide liquidity programmatically", "create LP position via API", "add liquidity via API", "increase liquidity", "decrease liquidity", "remove liquidity", "claim LP fees", "collect LP fees", "manage LP positions in code", or mentions building a backend, bot, or frontend that creates or manages Uniswap v2/v3/v4 liquidity positions through an API. Also use when debugging LP API calls (e.g. /lp/create, /lp/check_approval, /lp/increase, /lp/decrease, /lp/claim_fees), unexpected response fields, the approval or EIP-712 permit flow, or transaction-building errors for liquidity positions. For generating deep links to the Uniswap web app instead of calling the API, use the liquidity-planner skill; for using the Uniswap v4 SDK directly rather than the REST API, use the v4-sdk-integration skill.

# LP Integration

Integrate Uniswap liquidity provisioning into frontends, backends, and bots using the Uniswap LP API.

The LP API is a transaction-building service. You send position parameters; the API fetches live pool state, computes the dependent token amount, and returns a fully-formed, unsigned transaction. Your application signs and broadcasts it. The API never holds keys, never moves funds, and never broadcasts.

## Prerequisites

This skill assumes familiarity with viem basics (client setup, account management, contract interactions, transaction signing). Install the **uniswap-viem** plugin for comprehensive viem/wagmi guidance: `claude plugin add @uniswap/uniswap-viem`

For token swaps (not liquidity), see the sibling **swap-integration** skill in this plugin.

## Base URL

```text
LP_API_BASE_URL = https://liquidity.api.uniswap.org
```

All LP endpoints are POST requests under the `/lp/` prefix (e.g. `https://liquidity.api.uniswap.org/lp/create`).

> **The LP API host is intentionally different from the swap Trading API.** Liquidity provisioning lives at `https://liquidity.api.uniswap.org` (no `/v1` prefix), not the `https://trade-api.gateway.uniswap.org/v1` host used for swaps. Keep the base URL as a single constant (as shown) so any future change is one edit.
