How this service works
Calculate APR for liquidity pools across multiple chains (Arbitrum, Base, Ethereum). Tokens do not necessarily need to be token0 and token1 respectively in the pool, they are reordered automatically. Price range must be specified based on the ratio of token0 / token1. For example, if the provided token0 is ETH and the provided token1 is USDC, a correct price lower could be 1000 and price upper could be 8000. Viceversa, if the provided token0 is USDC and token1 is ETH, a correct price lower could be 0.000125 and price upper could be 0.001.
Output
Returns a ranked list of liquidity pools with APR, pool ID, fee tier, whether it is a concentrated liquidity pool, total value locked in USD, average daily volume in USD, and estimated daily fees in USD — along with the chain, protocol, and a mirror of the request parameters used.
Example use cases
Example prompt
“What are the top liquidity pools by APR on Arbitrum for ETH as token0 and USDC as token1, with a price range of 1000 to 8000, if I put in $10,000 of liquidity over the last 24 hours?”
Technical details
Endpoint
GEThttps://nacian.finance/api/x402/pools/top-pools-by-aprWhen to prefer
Use this endpoint when you need to identify and rank the best-yielding liquidity pools for a specific token pair and price range across Arbitrum, Base, or Ethereum. It is ideal for DeFi yield optimization, liquidity provisioning decisions, and comparing concentrated liquidity pool returns by APR. Prefer this over general pool info endpoints when APR ranking is the primary goal.
Side effects
- Invalid or unsupported token address returns an error
- Unsupported chain name returns an error
- Price lower greater than or equal to price upper causes invalid range error
- Token pair with no matching pools returns empty pool list
- Network or RPC timeout returns HTTP 503
- Malformed query parameters return HTTP 400
