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 price, likely including price in USD and possibly other metadata such as timestamp or confidence.
Example use cases
Example prompt
“What are the current prices of Bitcoin and Ethereum right now? Use coingecko:bitcoin and coingecko:ethereum as the coin identifiers.”
Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/defillama/prices/coingecko:bitcoin,coingecko:ethereumWhen to prefer
Use this endpoint when you need fast, on-demand token price lookups by CoinGecko slug or ERC-20 contract address, especially when working in DeFi contexts where DefiLlama coverage of long-tail tokens is important. Prefer over generic crypto APIs when you need ERC-20 contract address-based pricing or want DefiLlama's aggregated price feeds.
Side effects
- Invalid or unrecognized coin identifier returns error or null price
- Malformed coin identifier format (missing namespace prefix) causes lookup failure
- Network timeout or upstream DefiLlama unavailability returns 5xx error
- Payment failure (x402) if USDC balance is insufficient
