Using native gates with the IonQ API

**NOTE**: If request filters are provided, this endpoint will limit responses to 1 or more specific jobs based on those filters.<br /><br />
This endpoint retrieves all jobs this API key is authorized to view.


Get Jobs

To submit a program to be simulated or executed on our quantum hardware, `POST` it to the `jobs` endpoint.

Create a Job

Permanently remove many jobs from our platform. This cannot be undone.

Delete many Jobs

Get a specific Job

Permanently delete a job from our service. This cannot be undone.

Delete a Job

Retrieve a specific job's results by UUID.

Get a Job's output

Cancel the execution of a single job by ID.

Cancel a Job

Cancel the execution of many jobs at once by passing a list of jobs.

Cancel many Jobs

This endpoint retrieves an array of all available backend characterizations, with pagination.

This endpoint retrieves the most recent backend characterization data available.

Get the Most Recent Backend Characterization

This endpoint retrieves a characterization.

Retrieve a list of all available backends.

Get a usage report for the given organization from the start_date and end_date, detailing how much usage went to each QPU during that period. If no start_date or end_date are provided, period defaults to last 30 days until current time.
