Postpaid billing

We’re in the process of transitioning to postpaid billing, a flexible pay-as-you-go system. You pay only for the services used, without needing to purchase credits upfront. This option is not available for all Hume users quite yet. You can check Usage & Billing to see if postpaid billing is available for your account and reach out to our support team if you’re interested in getting early access.

Postpaid billing is a private beta feature, rolling out to a limited number of users over the next few weeks.

How it works

  1. Joining the platform: When you sign up and start using our API, you’ll initially be using the free credits given to every new account.
  2. Credit card requirement: Once you’ve exhausted your credit balance, you’ll need to add your credit card information to continue.
  3. Monthly limit and notifications:
    • You’ll have a default monthly limit of $100.
    • If you hit the $100 limit, API calls will return an error, and you’ll be prompted to apply for a limit increase.
  4. Billing notifications:
    • On the first of each month, you’ll receive an invoice for the previous month’s usage.
    • If your credit card is successfully added, it will be charged automatically.
    • You’ll get a confirmation email for successful transactions or an alert if a transaction fails.
  5. Failure to pay: If payment isn’t received within 7 days of the invoice date, API access will be suspended until the outstanding balance is settled.

Managing your account

  • Usage information: To view your monthly usage details, visit Usage & Billing. There you can track your API usage and see how much of your monthly limit has been utilized.
    • Note: After your prepaid credits are used, further usage accrues to your monthly cost. You’ll be charged this amount on the first of the following month. Your monthly cost is updated daily at 08:00 UTC.
  • Billing portal: To manage your billing details, navigate to Usage & Billing and select Manage payments and view invoices. There you can update your payment method, view past invoices, and keep track of upcoming charges.

Billing methodology

  1. Audio and video:
    • Our listed prices are presented per minute for ease of understanding.
    • However, we bill these services on a corresponding per-second basis to ensure precise and fair charges. This means you are only billed for the exact amount of time your audio or video content is processed.
  2. Image and text:
    • Image processing charges are incurred per image.
    • Text processing is billed based on the number of words processed.
