Use this endpoint when you need real-time onchain DEX prices for tokens on the Base network by contract address, especially for tokens that may not appear in CoinGecko's centralized exchange listings. Ideal for DeFi agents needing fresh price data without relying on CEX feeds. Supports batch lookups for multiple contracts in one call.
Side effects
- Invalid or unrecognized contract address returns empty or null data for that token
- Unsupported network returns 404 or empty response
- Too many contract addresses in one request may result in truncated or error response
- Rate limit exceeded returns 429 error
- Token with no DEX liquidity returns null price
