Onramping with the API

To get an onramp link and quote using the Universal Bridge API, use the following:

const res = await fetch('https://bridge.thirdweb.com/v1/onramp/prepare', {
    method : 'POST',
    headers: {
      'Content-Type': 'application/json',
      'x-secret-key': process.env.THIRDWEB_SECRET_KEY,
    },
    body: JSON.stringify({
      onramp:      'transak',
      chainId:     4337,
      tokenAddress:'0xAFf7314Bc869f4AB265ec7EfA8E442F1D978d7a',
      maxSteps:    2,
      amount:      '200000000000000000',
      currency:    'USD',
      receiver:    '0x2a4f24f935eb178e3e7ba9b53a5ee6d8407c0709',
    }),
});

const data = await res.json();

The returned quote will look something like this:

You can then use the top-level id to get the onramp's status:

const res = await fetch('https://bridge.thirdweb.com/v1/onramp/status?id=3179cf89-e915-4103-b61e-991bf3a33e93', {
    method : 'GET',
    headers: {
      'Content-Type': 'application/json',
      'x-secret-key': process.env.THIRDWEB_SECRET_KEY,
    },
});

const data = await res.json();

The returned status:

{
    "data": {
        "status": "COMPLETED",
        "transactions": [
            {
                "chainId": 4337,
                "transactionHash": "0xd36a649a23044e980446a3183c6cfe9016d539a6ff88f31b611a1614b1d265aa"
            }
        ],
        "purchaseData": null
    }
}
