'fetch' API Method

POST https://api.bws.ninja/v1/fetch

Blockchain operations are mostly asynchronous, meaning you request something and need to wait until the response or confirmation is available.

Because of that, you will find most Blockchain Web Services API calls are also asynchronous, meaning you get a jobId you can use it to fetch the operation status and results.

CODE EXAMPLE

Javascript code example to 'fetch' job status and results.

var parameters = {
  "jobId": "b064cc6b-f394-4ca4-9c51-be506e4cc59d",
};

$.ajax({
  method: 'POST',
  url: 'https://api.bws.ninja/v1/fetch',
  dataType: 'json',
  data: JSON.stringify(parameters),
  headers: {
    'Content-Type': 'application/json',
    'X-Api-Key': 'ExV0d92KzQ8QgsTVnevddpbB8cUaAfPs7ntVF8g0'
  }
});
