About Price API

Price API provides access to real-time market prices for any token pair across 4 million tokens covering 11 different chains. It allows you to get accurate pricing data with high throughput to power high-frequency data requests.

info

Price API is in beta. Its recommended use is for checking prices, not be be used for trading purposes. For example, if you plan to use this in a trading workflow that is triggered by price changes of USDC, be aware this is subject to the risk that the stablecoin may depeg.

Get a token price in USD terms via stablecoins

Use the /swap/v1/price endpoint to get the real-time price of the token pair.

In this example, we want the price of WETH in terms of USDC. To do this, we will use the stable coin USDC as the sellToken. We use the following params:

  • sellToken=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 - USDC token address
  • buyToken=0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2 - WETH token address
  • sellAmount=10000000 - 10 USDC (USDC has a base unit of 6)
info

The price returned is in buyToken terms, (sellToken/buyToken = USDC/WETH = 0.000486899453497844).

To obtain the price in USD terms, simply take the inverse (WETH/USDC = 1/0.000486899453497844 = 2053).

Do not explicity set buyAmount in the request; it will not return back the desired result.
