How this service works
Current USD price of one or more cryptocurrencies (ETH price, BTC price, any token by symbol or contract address), source DefiLlama. Parameter: ?coins=ethereum,bitcoin (comma-separated CoinGecko IDs, or 'chain:address' for a specific token, e.g. ethereum:0xdac17f958d2ee523a2206206994597c13d831ec7).
Output
A JSON object mapping each requested coin identifier to its current USD price, token symbol, and a confidence score (0–1). Also includes the source URL (coins.llama.fi), the currency (USD), and an ISO timestamp of when the data was fetched.
Example use cases
Portfolio valuation snapshot
“I hold ETH, BTC, and SOL — can you pull their current USD prices so I can calculate the value of my portfolio?”
DeFi token price by contract
“What's the current USD price of the token at Ethereum address 0xdac17f958d2ee523a2206206994597c13d831ec7? Use the chain:address format.”
Multi-coin price alert check
“Fetch the live prices for bitcoin, ethereum, and solana from DefiLlama and tell me if any of them have crossed their round-number thresholds I'm watching.”
Technical details
Endpoint
GEThttps://x402-seller-0ay3.onrender.com/api/defi/priceWhen to prefer
Choose this endpoint when you need real-time USD prices for one or more cryptocurrencies and want DefiLlama as the data source. It supports both CoinGecko IDs (e.g. 'ethereum', 'bitcoin') and on-chain contract addresses via the 'chain:address' syntax, making it ideal for DeFi tokens that may not have a standard CoinGecko ID. Prefer it over generic price APIs when you need confidence scores alongside prices, or when querying obscure ERC-20 or cross-chain tokens by contract.
Side effects
- Unknown coin ID returns a missing or null entry for that coin
- Malformed chain:address format results in a lookup failure for that token
- DefiLlama upstream outage causes the endpoint to return an error or stale data
- Empty or missing 'coins' query parameter results in a 400-level error
- Rate limiting or payment failure returns a 402 Payment Required response
