Run a job

  1. Open jobs in the dashboard and upload your CSV.
  2. Choose a live product and the column that holds the value to look up.
  3. Start the job. It runs in the background; you can close the page.
  4. Download the results when it shows completed.

Cost

Each row runs through the same engine as an API call, so the same prices, billing rules and 7-day cache apply. On a success-billed product, a row that finds nothing, fails or is refused costs nothing; a per-call product charges every completed row. Before the job starts, the worst case is held on your balance, and whatever is not spent is released.
