Endpoint
GEThttps://pro-api.coingecko.com/api/v3/x402/onchain/simple/networks/base/token_price/0x0b3e328455c4059eeb9e3f84b5543f74e24e7e1b,0x22af33fe49fd1fa80c7149773dde5890d3c76f3b,0xacfe6019ed1a7dc6f7b508c02d1b04ec88cc21bf,0x9b5e262cf9bb04869ab40b19af91d2dc85761722,0x296eb9c4d8fcbd00fbc6d5027e4202bf955fa76fWhen to prefer
Use this endpoint when you need real-time onchain DEX prices for one or more specific token contract addresses on the Base network — especially when you want data sourced directly from liquidity pools rather than centralized exchange feeds. Ideal for DeFi portfolio tools, trading bots, or price alerts targeting Base chain tokens. Prefer this over CoinGecko's standard coin price endpoint when you have contract addresses but not CoinGecko coin IDs, or when onchain/DEX-sourced prices are specifically required.
Side effects
- Invalid or unrecognized contract address returns missing or null data for that token
- Network not supported returns 404 or empty response
- Malformed contract address format returns 400 bad request
- Rate limiting or missing API key returns 429 or 401
- Token has no onchain liquidity or DEX pool returns empty price data
