# ParaSwap.io API
ParaSwap API allows any developer to retrieve Token prices as well as making swaps or payments using ETH and ERC-20 tokens.
We tried, as much as possible, to make it very simple to integrate. All you need is 2 API calls (get price & build tx) for making a swap or a payment.
Developers can also use our JS/TS SDK for web and Node.js integrations https://www.npmjs.com/package/paraswap
