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 current USD prices for each requested coin identifier, keyed by the coin identifier string (e.g. coingecko:bitcoin -> price value).
Example use cases
Example prompt
“What are the current prices of Bittensor and Artificial Superintelligence Alliance — look them up via coingecko identifiers coingecko:bittensor and coingecko:artificial-superintelligence-alliance.”
Technical details
Endpoint
GEThttps://blockrun.ai/api/v1/defillama/prices/coingecko:artificial-superintelligence-alliance,coingecko:bittensorWhen to prefer
Use this endpoint when you need real-time token price data for one or more cryptocurrencies identified by CoinGecko slugs or on-chain contract addresses, especially in a pay-per-call context without needing a persistent API key. Prefer this over alternatives when working in a Web3/agent context that already handles x402 micropayments.
Side effects
- Invalid or unrecognized coin identifier returns an error or missing entry in the response
- Comma-separated list with a malformed identifier may cause partial or full failure
- Network or upstream DefiLlama API outage returns a 5xx error
- Payment failure (x402) if USDC balance is insufficient
