# DefiLlama API

> DefiLlama returns DeFi project, blockchain, stablecoin, and yield data as a workflow and API.

DefiLlama returns a project's TVL, chain breakdown, token details, and daily history from a project name, link, or slug. List top blockchains ranks chains by DeFi TVL, with an optional maximum result count. List stablecoins filters supply and peg data by peg; List best yields ranks pools by asset, with optional chain and pool-size filters.

## Methods

### Get defi project

Operation `get_defi_project`, version 1. 1 credit per completed call. Failed calls without a completed billing receipt are free; completed work can remain charged if delivery is interrupted.

Get a DeFi project’s current TVL, 1-day and 7-day changes, chain breakdown, token information, and daily TVL history. Parent projects combine their listed versions; changes are calculated from available historical TVL observations.

**Input**

| Field | Type | Required | Example | Description |
|---|---|---|---|---|
| `project` | string | yes | `"Uniswap"` | Project name, DefiLlama project link, or slug, for example Aave. |
