# Limits

> How many requests and jobs you can have at once. A request over a limit is refused with a Retry-After, never queued, never charged.

## Request and job limits

Requests per minute, in fixed 60-second windows. Each is counted for the key and for every key on the same paying account together.

| Class | What counts | Per key | Per account |
| --- | --- | --- | --- |
| `start` | A paid start (`make_video`, `make_image`, `edit_image`, `recast`, `make_music`, `creator_video`, `run_template`) | 10 | 30 |
| `quote` | A `dry_run` call, and `GET /models` with a key | 60 | 180 |
| `read` | `GET /results`, `GET /results/{id}`, `GET /templates`, the callback log | 120 | 360 |
| `upload` | `POST /uploads` | 30 | 60 |
| `write` | Drafting an ads launch | 20 | 40 |

- **Jobs at once:** up to 8 jobs queued or running per paying account. A key can carry a lower limit of its own. Test-key runs do not count.
- **Test keys:** up to 200 test runs per person per 24 hours (`TEST_LIMIT`).

Over a request limit the answer is `429 RATE_LIMITED` with `Retry-After` (seconds to the end of the window). A refused request still counts, so waiting works better than hammering. Over the jobs limit the answer is `429 CONCURRENCY_LIMIT` with `Retry-After: 15`. Work you already started keeps running.

If our own capacity is full the answer is `503 PROVIDER_BUSY`. That is not your fault and nothing is charged; retry after `Retry-After`.

## Money limits

You can cap spend per key and per account, per day and per month, on the Developers page. Over a cap the answer is `402 BUDGET_EXCEEDED` with `budget.resets_at`. It never triggers an automatic top-up.

## Keys

At most 25 active keys per person, and 20 new keys an hour (`KEY_LIMIT`). Too many bad keys from one address in a minute answers `AUTH_RATE_LIMITED`.

## How to read your limits in code

Poll politely: every 15 to 30 seconds for a job, or use a [callback](https://diffusr.ai/docs/callbacks). Dry runs have their own, larger limit (`quote`), so check prices as often as you need.

## Asking for more

If you need higher limits, [book a call](https://cal.com/sharan-mansukhani-hfdv4n/diffusr?overlayCalendar=true) or write to hello@diffusr.ai. Say your use, how many jobs at once, and how many requests a minute.
