Uniswap API (Subgraph)

UpFreefinancial

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.

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)

Example request

Generic template — replace <endpoint> with the real path from the docs.
curl https://uniswap.org/<endpoint> \
  -H "Authorization: Bearer $API_KEY"
# Some providers use X-Api-Key instead — verify in the docs.

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.).
