Uniswap API (Subgraph)
Uniswap API (Subgraph)
Uniswap doesn't have traditional REST API — on-chain data is queried via The Graph's official Uniswap subgraphs (v2/v3/v4): pools, trades, liquidity, price history.
Data from world's largest DEX
No "place order API" — Uniswap is AMM; to trade, use SDK to sign on-chain transactions via wallet
Get API key from The Graph studio. POST GraphQL to Uniswap V3 subgraph endpoint.

About this API
Uniswap is the largest decentralized exchange launched in 2018, pioneering the AMM (automated market maker) model — no order book; users trade against liquidity pools with price determined by token ratio (xy=k formula). Unlike centralized exchanges, Uniswap has no "API order placement" — any "trade" is a wallet-signed swap transaction on-chain. But Uniswap data queries go through The Graph's official subgraph — developers use GraphQL to query any pool, any token's swap history, TVL, APY, etc. Three versions each have a subgraph: v2 (classic AMM), v3 (concentrated liquidity, 2021), v4 (hooks, 2024). Most common developer uses: get real-time token prices as price oracle (avoid centralized oracle risk), compare Uniswap prices for arbitrage, LP yield tracking.

Strengths & limitations
Strengths
- Data from world's largest DEX
- Flexible GraphQL queries
- Subgraph data pre-aggregated (no raw event scanning needed)
Limitations
- No "place order API" — Uniswap is AMM; to trade, use SDK to sign on-chain transactions via wallet
- Subgraph has indexing lag (seconds to minutes)

FAQ
How do I "place an order on Uniswap"?+
No API. Use Uniswap SDK (@uniswap/v3-sdk) to construct swap transactions; sign with wallet and submit on-chain.
What's the price lag?+
Subgraph typically 5-30s delay. For real-time, query pool state directly via RPC node (uniswapV3Pool.slot0(), etc.).
