How this service works
Crypto price in USD for up to 20 coins (BTC, ETH, SOL...) or tokens by chain:address, from DefiLlama. Input: 'BTC,ETH'.
Output
A JSON object containing an array of price results, each with the coin key (e.g. coingecko:bitcoin), original query string, symbol, current USD price, Unix timestamp, and confidence score. Also includes the data source (DefiLlama coins API) and a list of any unresolved coin queries.
Example use cases
Portfolio value snapshot
“Can you grab the current USD prices for BTC, ETH, SOL, AVAX, and MATIC so I can calculate the total value of my crypto holdings?”
DeFi token price by address
“What's the current USD price of the token at address 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 on Ethereum?”
Arbitrage spread check
“Fetch the latest USD prices for BTC and ETH — I want to compare them against another exchange to see if there's a spread.”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/crypto-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time USD prices for one or more cryptocurrencies by ticker symbol or on-chain token address, especially when DefiLlama coverage is desired. It handles both well-known coins (BTC, ETH) and obscure DeFi tokens via chain:address lookup in a single call, making it ideal for portfolio calculations, price checks, or DeFi analytics. Prefer this over CoinGecko-direct or CoinMarketCap integrations when you need DefiLlama's broad DeFi token coverage.
Side effects
- Unknown or misspelled coin symbol returns it in the 'unresolved' array rather than throwing an error
- Invalid chain:address format may result in unresolved entry
- Exceeding 20 coins in a single request may result in truncation or error
- DefiLlama upstream outage may cause stale or unavailable prices
- Very new or illiquid tokens may have no price data and appear as unresolved
