Top DEX pools by TVL
POST /api/dex-top-poolsTop DEX pools (Uniswap, Sushi, Curve, Aerodrome, etc.) ranked by current TVL - filterable by chain and project. Sourced from DeFiLlama's public Yields API (keyless). Each row carries chain, project slug, symbol pair, TVL in USD, current APY, and pool ID for follow-up queries.
Input
| Field | Type | Description |
|---|---|---|
chain | string | Chain name as DeFiLlama uses it (Ethereum, Base, Polygon, Arbitrum, Optimism, etc.). Case-insensitive. Omit for all chains. |
project | string | Project slug substring (uniswap-v3, aerodrome-v1, curve-dex, etc.). Case-insensitive substring match. Omit for all DEXes. |
limit | number | Max pools to return (1-50, default 10). |
