@0x/swap-ts-sdk
A TypeScript client to interact with 0x API. Currently @0x/swap-ts-sdk
supports 0x API v2 "Swap" and "Gasless" endpoints.
Note:
@0x/swap-ts-sdk
is meant for server side use only. Using the SDK from a browser is not supported.
Setup
pnpm add -E @0x/swap-ts-sdk
Important: TypeScript needs to be configured with compilerOptions.strict
set to true
. The client won't correctly type check if TypeScript is not in strict
mode.
Visit 0x.org to get your API key.
Usage
Create a "vanilla" Node client with createClientV2
:
import { createClientV2 } from '@0x/swap-ts-sdk';
const client = createClientV2({
apiKey: '33da2...91ebf9',
});
const price = await client.swap.permit2.getPrice.query({
buyToken: '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2',
chainId: 1,
sellAmount: '1000000000000000000',
sellToken: '0xdAC17F958D2ee523a2206206994597C13D831ec7',
});
API reference
Visit docs.0x.org for the API specification.
Client documentation
The @0x/swap-ts-sdk
client is a wrapped & typed tRPC v10.x client.
Visit https://trpc.io/docs/v10/client for full documentation, including how to use the client with Next.js, React Query, or vanilla Node.
Aborting calls (timeout)
import { createClientV2 } from '@0x/swap-ts-sdk';
const client = createClientV2({
apiKey: '33da2...91ebf9',
});
const quote = await client.gasless.getQuote.query(
{
buyToken: '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2',
chainId: 1,
sellAmount: '1000000000000000000',
sellToken: '0xdAC17F958D2ee523a2206206994597C13D831ec7',
taker: '0x60B4f0e1DF30c8c0f0b0c8BEc8787E7564647a80',
txOrigin: '0x60B4f0e1DF30c8c0f0b0c8BEc8787E7564647a80',
},
{
signal: AbortSignal.timeout(1000),
},
);
Using with Next.js
You can use @trpc/next
directly to use the SDK with Next.js. See the documentation
here: https://trpc.io/docs/v10/client/nextjs/ssr.
To type the client, the packages exports the router type:
import type { RouterV2 } from '@0x/swap-ts-sdk';
import { httpLink } from '@trpc/client';
import { createTRPCNext } from '@trpc/next';
export const trpc = createTRPCNext<RouterV2>({
config(_opts) {
return {
links: [
httpLink({
headers: {
'0x-api-key': 'your-api-key',
'0x-version': 'v2',
},
url: 'https://api.0x.org/trpc/swap',
}),
],
};
},
ssr: true,
});
