# Removes legacy usage-based billing

## What’s new

We’ve removed support for legacy usage-based billing. You can no longer create a [price](https://docs.stripe.com/api/prices/object.md?api-version=2025-03-31.basil) with a [usage_type](https://docs.stripe.com/api/prices/object.md?api-version=2025-02-24.acacia#price_object-recurring-usage_type) of `metered` without a specified [meter](https://docs.stripe.com/api/prices/object.md?api-version=2025-02-24.acacia#price_object-recurring-meter). We’ve also removed the [billing_thresholds](https://docs.stripe.com/api/subscriptions/object.md?api-version=2025-02-24.acacia#subscription_object-billing_thresholds) from the subscription endpoints.

We’ve removed [billing_thresholds](https://docs.stripe.com/api/subscriptions/object.md?api-version=2025-02-24.acacia#subscription_object-billing_thresholds) and [aggregate_usage](https://docs.stripe.com/api/prices/object.md?api-version=2025-02-24.acacia#price_object-recurring-aggregate_usage) from all API endpoints. You can no longer create legacy usage-based prices or attach existing legacy usage-based prices to quotes, upcoming invoices, or subscriptions.

A legacy usage-based price is defined as a price with a [usage_type](https://docs.stripe.com/api/prices/object.md?api-version=2025-02-24.acacia#price_object-recurring-usage_type) of `metered` without a specified [meter](https://docs.stripe.com/api/prices/object.md?api-version=2025-02-24.acacia#price_object-recurring-meter).

## Why is this a breaking change?

- Removed `billing_thresholds` from [Subscription](https://docs.stripe.com/api/subscriptions/object.md?api-version=2025-03-31.basil) endpoints.
- Removed `aggregate_usage` from [Price](https://docs.stripe.com/api/prices/object.md?api-version=2025-03-31.basil) endpoints.
- Using `usage_type` of `metered` without a specified `meter` now returns an error on [Price](https://docs.stripe.com/api/prices/object.md?api-version=2025-03-31.basil) creation.
- Removed support for attaching prices of `usage_type=metered` without a set `meter` to Subscriptions, Subscription Schedules and Quotes.

## Impact
