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 (e.g. 'coingecko:bitcoin') to its current USD price and the timestamp of the price data, sourced from DefiLlama's aggregated pricing feeds.
Example use cases
DeFi portfolio valuation
“I need the current USD prices for coingecko:ethereum, coingecko:bitcoin, and coingecko:chainlink so I can calculate the total value of my crypto holdings.”
Stablecoin peg monitoring
“Can you check the current prices of coingecko:usd-coin and coingecko:tether to make sure they're both holding their dollar peg?”
ERC-20 token price lookup
“What's the current USD price of the WETH token at Ethereum contract address 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2?”
Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/defillama/prices/coingecko:usd-coin,coingecko:tetherWhen to prefer
Choose this endpoint when you need real-time token prices for one or more cryptocurrencies and want to identify tokens by CoinGecko slug or on-chain contract address. It supports batch lookups in a single call, making it efficient for portfolio valuation or multi-token comparisons. Prefer this over general market data APIs when working in a DeFi or blockchain context where contract address-based token identification is needed.
Side effects
- Invalid or unrecognized coin identifier returns missing or null price entry
- Unsupported contract address chain prefix causes lookup failure
- Malformed comma-separated list may result in partial or empty response
- Rate limits or payment failures ($0.002 USDC per call via x402) prevent response
- Very new or illiquid tokens may have no price data available
