How this service works
Query onchain DEX token price & market data based on the provided token contract addresses on a network.
Output
A JSON object mapping each queried contract address to its current onchain price in USD, along with optional fields such as 24-hour trading volume, market cap, 24-hour price change percentage, and total reserve in USD — all sourced from DEX liquidity pools on the Base network.
Example use cases
DeFi portfolio value tracker
“I have a few tokens on Base that I bought through a DEX and they're not on Coinbase or Binance. Can you look up the current USD prices, 24-hour volume, and price change for these contract addresses: 0x940181a94A35A4569E4529A3CDfB74e38FD98631 and 0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22?”
New token launch price monitor
“There's a newly launched token on Base that just went live on Uniswap. I only have the contract address — 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA. Can you pull its current onchain price, trading volume, and any available market cap data from DEX pools?”
Base DEX arbitrage opportunity check
“I want to compare market data across a handful of Base network tokens to spot any unusual price movements or volume spikes. Can you fetch the current price, 24-hour price change percentage, and total reserve in USD for these contracts: 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb, 0x4621b7A9c75199271F773Ebd9A499dbd165c3191, and 0xfde4C96c8593536E31F229EA8f37b2ADa2699bb2?”

Use this endpoint when you need real-time onchain DEX prices for one or more specific ERC-20 token contract addresses on the Coinbase Base network, especially when the tokens may not be listed on centralized exchanges. Prefer this over CoinGecko's standard /simple/price endpoint when dealing with newly launched or DEX-only tokens identified by contract address rather than coin ID. Ideal for DeFi dashboards, portfolio trackers, or agents monitoring Base network token values.
Side effects
- Invalid or unsupported contract address returns missing or null price data for that token
- Network not supported returns 404 or empty response
- Malformed contract address format causes 400 Bad Request
- Rate limiting or missing API key returns 401/429 error
- Token with no DEX liquidity on Base returns null price
- Truncated or overly long contract address list may cause request URI too large error
