How this service works
Token price lookup. Pass coin identifiers as `/v1/defillama/prices/{coins}` (e.g. `coingecko:bitcoin`, `ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`). Supports comma-separated lists.
Output
Returns a JSON object mapping each coin identifier to its current USD price, sourced from DefiLlama price feeds. Supports both CoinGecko slug format (e.g. coingecko:bitcoin) and Ethereum contract address format (e.g. ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2).
Example use cases
Track portfolio holdings in USD
“I need to check what my current token positions are worth in dollars. Can you look up the prices for my Ethereum holdings at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2, my USDC at ethereum:0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, and my Aave at ethereum:0x7Fc66500c84A76Ad7e9c93437E434122A1f9AcDe?”
Monitor DeFi token price changes
“Can you fetch the latest USD prices for a batch of major DeFi tokens? Get me coingecko:aave, coingecko:uniswap, coingecko:curve, and coingecko:maker so I can see how they're moving right now.”
Verify swap rates before executing
“Before I execute a token swap, I need to confirm the current prices. What are the USD prices for coingecko:ethereum and coingecko:dai right now? I want to make sure I understand the exchange rate.”
