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
A JSON object mapping each requested coin identifier to its current USD price, returned for all coins supplied in the path parameter as a comma-separated list.
Example use cases
DeFi portfolio valuation snapshot
“Can you look up the current prices for coingecko:aerodrome-finance, coingecko:brett, and coingecko:nomad so I can calculate the current value of my holdings?”
ERC-20 token price by contract
“What's the current USD price of the WETH token at Ethereum address 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2?”
Multi-token price alert check
“Fetch the latest prices for coingecko:bitcoin and coingecko:ethereum so I can check if either has crossed my alert thresholds.”
Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/defillama/prices/coingecko:nomad,coingecko:aerodrome-finance,coingecko:brettWhen to prefer
Choose this endpoint when you need real-time token prices using CoinGecko slugs or on-chain contract addresses, especially for DeFi tokens not easily found on centralized exchanges. It's ideal for batch multi-token price lookups in a single call and integrates DeFiLlama's broad cross-chain coverage at a very low per-call cost ($0.002 USDC).
Side effects
- Unknown or misspelled coin identifier returns no data or an error for that token
- Invalid format for contract address causes lookup failure
- Comma-separated list with unsupported coin platforms may return partial results
- Network or upstream DeFiLlama API downtime results in a 5xx error
- Rate limiting or payment failure (x402) blocks the request
