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 identifier string (e.g. coingecko:optimism). Includes price and likely timestamp/confidence metadata from DefiLlama's price feed.
Example use cases
Example prompt
“What are the current prices for Optimism and Avalanche? Look them up using their CoinGecko IDs: coingecko:optimism and coingecko:avalanche-2.”
Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/defillama/prices/coingecko:optimism,coingecko:avalanche-2When to prefer
Use this endpoint when you need current spot prices for one or more crypto tokens and can identify them by CoinGecko slug or EVM contract address. Ideal for DeFi portfolio valuation, arbitrage checks, or enriching on-chain data with USD prices. Prefer over exchange-specific endpoints when you need aggregated/cross-market pricing via DefiLlama.
Side effects
- Invalid or unrecognized coin identifier returns empty or error result
- Comma-separated list with one bad identifier may cause partial or full failure
- Rate limiting or payment failure returns 402
- Network timeout or DefiLlama upstream unavailability causes 5xx error
- Malformed path parameter (missing prefix like 'coingecko:') returns no price data
