How this service works
Query onchain DEX token price & market data based on the provided token contract addresses on a network.
Output
Returns a JSON object containing the USD price of the queried token(s) sourced from onchain DEX data on the Optimism network, with optional fields including 24-hour trading volume, market capitalization, 24-hour price change percentage, and total reserve in USD. Data reflects real-time DEX liquidity pool pricing.
Example use cases
DeFi portfolio price tracking
“What's the current DEX price and market cap for the token at contract 0x7F5c764cBc14f9669B88837ca1490cCa17c31607 on Optimism? Also include the 24-hour price change.”
Arbitrage opportunity detection
“Fetch me the onchain DEX price and 24-hour trading volume for these two Optimism token contracts — 0x4200000000000000000000000000000000000042 and 0xDA10009cBd5D07dd0CeCc66161FC93D7c9000da1 — so I can compare them for an arbitrage check.”
DeFi liquidity reserve monitoring
“Check the total reserve in USD and current price on the DEX for the token at contract 0x8700dAec35aF8Ff88c16BdF0418774CB3D7599B4 on Optimism — I want to see if liquidity is healthy enough to trade.”
Technical details
Endpoint
GEThttps://pro-api.coingecko.com/api/v3/x402/onchain/simple/networks/optimism/token_price/probeWhen to prefer
Use this endpoint when you need real-time onchain DEX token prices specifically on the Optimism (OP) network and have a token contract address. Prefer this over CoinGecko's standard token price endpoints when you need DEX-sourced liquidity data (not CEX prices) or when the token is only traded onchain. Choose network-specific sibling endpoints for Base, Ethereum, or other chains.
Side effects
- Invalid or unrecognized contract address returns empty or null price data
- Token not listed on any Optimism DEX returns no data
- Network-specific endpoint only covers Optimism — requests for other chains will require different endpoints
- Rate limiting or payment failure results in 402 or 429 error
- Inactive token sources excluded unless include_inactive_source is set to true
