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 current USD price data for each requested coin identifier, keyed by the coin slug or contract address provided (e.g. coingecko:bitcoin → price in USD).
Example use cases
Example prompt
“What are the current prices of Polygon and Arbitrum? Look them up using their CoinGecko identifiers coingecko:polygon and coingecko:arbitrum.”
Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/defillama/prices/coingecko:polygon,coingecko:arbitrumWhen to prefer
Use this endpoint when you need fast, pay-per-call token price lookups without managing API keys, especially for DeFi tokens identifiable by CoinGecko slug or EVM contract address. Prefer over CoinGecko direct API when you want micropayment billing via USDC on Base with no subscription. Ideal for multi-token price fetches in a single call.
Side effects
- Unknown or misspelled coin identifier returns null or missing data for that coin
- Invalid coin format (not coingecko: or chain:address) may return error or empty result
- Rate limits or payment failure (x402) if USDC balance is insufficient
- Network timeout if DeFiLlama upstream is slow or unavailable
- Comma-separated list too long may cause URI length issues
