# quota_exhausted

Monthly API quota exhausted. What causes the BioFlow API's quota_exhausted error (HTTP 429) and how to fix it.

HTTP 429 · `application/problem+json` · Monthly API quota exhausted.

## What causes it

- The workspace used its full monthly API quota (successful /v1 requests per calendar month, UTC).

## How to fix it

- Check where you stand with `GET /v1/usage` (it's free — it never counts against the quota).
- Wait for the calendar-month reset, or upgrade the plan for a higher quota (see [pricing](https://getbioflow.com/pricing)).
