Free Multichain Liquidity Pool Data API for Developers

BaniPool's multichain liquidity pool data API gives developers the same data shown on the site: pools, TVL, volume, Fee APR, tokens, wallet balances and LP positions across 9 EVM networks and Solana, plus simulated transaction quotes and plans and realtime events. Public reads are free without a key (rate-limited per IP); an API key adds a fixed quota and access to transaction endpoints.

Get started in 3 steps

1. Log in with a wallet on the Developers page — no gas, no transaction permission.
2. Create an API key with the scopes you need (e.g. data:read). The secret is shown once — store it on your server.
3. Call the API with the x-api-key header.

Example: top 5 pools on Base by TVL.

curl -s "https://banipool.com/api/v1/pools?chain=base&sort=tvl_desc&limit=5" -H "x-api-key: $BANIPOOL_API_KEY"

Available data

The full list, schemas and error codes are in the API documentation and a downloadable OpenAPI file.

Ideas
