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 containing the current USD price(s) for the requested coin identifiers, keyed by the coin identifier string (e.g. coingecko:bitcoin). Each entry typically includes the price value and a timestamp of when the price was last updated, sourced from the DeFiLlama price aggregator.
Example use cases
Live portfolio valuation for DeFi holdings
“I hold coingecko:bitcoin, coingecko:ethereum, and coingecko:uniswap — can you fetch the current prices for all three so I can calculate my total portfolio value?”
Contract address price check for on-chain token
“What's the current price of the WETH token at Ethereum contract address 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2?”
Crypto price alert bot data feed
“Fetch the latest price for coingecko:base-protocol so I can check if it's crossed my alert threshold of $0.50.”
Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/defillama/prices/coingecko:base-protocolWhen to prefer
Use this endpoint when you need real-time token price lookups across a wide range of assets including both CoinGecko-listed tokens and arbitrary ERC-20 contracts by address. It is particularly useful for DeFi-native workflows where you may have contract addresses rather than named tokens, or when you need to price multiple tokens in a single call. Prefer this over CoinGecko direct API when you want DeFiLlama's aggregated pricing and the x402 micropayment model suits your agent's billing setup.
Side effects
- Invalid or unknown coin identifier returns an empty result or error for that token
- Malformed identifier format (missing prefix like 'coingecko:') may result in no data returned
- Network or upstream DeFiLlama API unavailability causes 5xx errors
- Payment failure (insufficient USDC balance) results in 402 Payment Required
- Rate limiting may apply if many requests are sent in rapid succession
