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 in USD).
Example use cases
Example prompt
“What are the current prices of Bitcoin and Ethereum? Use their coingecko identifiers coingecko:bitcoin and coingecko:ethereum.”

Side effects
- Invalid or unrecognized coin identifier returns no data or an error
- Comma-separated list with one bad identifier may cause partial or full failure
- Network or upstream DefiLlama unavailability returns a 5xx error
- Unsupported chain/contract address format returns empty result
- Payment of 0.001 USDC not provided causes 402 Payment Required
