# Pricing and limits

> Free during the beta: 30 minutes of audio a month for every account. Here is how it is counted, and the limits on each request.

## Free during the beta

Every account gets **1,800 seconds (30 minutes) of audio a month**, free. The count starts again on the first day of each month (UTC). There is no card to enter and no paid plan yet. If you need more for a pilot, [write to us](https://developers.namuai-lab.com/resources/support.md) with what you are building.

## What counts

Usage is counted in **seconds of audio**, the same unit for every endpoint:

| Request | What it counts |
| - | - |
| `POST /v1/transcribe` | the length of the audio you send |
| `POST /v1/speech` | the length of the audio you get back |
| `POST /v1/translate` with audio | the length of the audio you send |
| `POST /v1/translate` with text | the number of characters ÷ 15, plus the spoken translation if you ask for it |
| `POST /v1/converse` | the audio you send plus the spoken reply |
| `GET` requests | nothing |

**A request that fails counts nothing.** The allowance is checked before each request, so the last request of a month can take you a little past it.

See where you stand in the [console](https://www.namuai-lab.com/account/usage), or in code with [`GET /v1/usage`](https://developers.namuai-lab.com/api-reference/account/get-usage):

```json theme={null}
{ "month_audio_seconds_used": 312.4, "month_audio_seconds_limit": 1800.0 }
```

When the month's allowance is used, requests return `429 quota_exceeded` until the next month.

## Limits on each request

| Limit | Value | Error when passed |
| - | - | - |
| Audio file size | 25 MB | `413 payload_too_large` |
| Audio length | 300 seconds (5 minutes) | `413 audio_too_long` |
| Text length | 2,000 characters | `413 text_too_long` |
| Requests per key | 60 a minute by default | `429 rate_limited`, with `Retry-After` |
| Active keys per account | 10 | shown in the console |

Every request counts toward the per-minute limit, including one that is refused for a bad body. For longer recordings, cut them into pieces under five minutes ([how](https://developers.namuai-lab.com/guides/audio-formats.md#long-recordings)).

> Need a higher rate limit for a launch or a pilot? We can raise it per key. [Ask us](https://developers.namuai-lab.com/resources/support.md).
