# API Rate Limits

> **Info**
>
> Rate limits vary by region. North America, Europe, Australia, and India limits are shown separately for each service.
>
> * **North America:** `api.deepgram.com`
> * **Europe:** `api.eu.deepgram.com`
> * **Australia:** `api.au.deepgram.com`
> * **India:** `api.in.deepgram.com`

## Pay as You Go

Limits to consider if you use the Pay as You Go plan with Deepgram.

> **Rate limits apply per project**
>
> Rate limits apply per project, not per account or API key. Creating additional projects under the same account will not grant you additional concurrency. Secondary projects created on a self-serve account are limited to a single concurrent stream by design. Bypassing rate limits by spreading traffic across multiple projects violates our Terms of Service.
>
> If you need higher concurrency, [contact sales](https://deepgram.com/contact-us) about a growth or enterprise agreement.

## Scaling beyond default limits

Rate limits are scoped to a project. One customer maps to one project for the purposes of these limits. Multiple API keys inside a single project all draw from that project's concurrency pool. Adding more projects under the same account does not increase the concurrency available to you.

### If you are hitting your limits

Consolidate your traffic into a single project, then [contact sales](https://deepgram.com/contact-us) about moving to a Growth or Enterprise agreement with a higher concurrency allocation.

### What not to do

Do not create additional projects, additional accounts, or otherwise distribute traffic across projects to work around per-project limits. These setups are detected. Secondary projects on a self-serve account are restricted to 1 concurrent stream, and bypassing rate limits this way violates our Terms of Service.

### REST API rate limits

The concurrency limits on this page apply to inference endpoints (Speech-to-Text, Text-to-Speech, Voice Agent, Intelligence). REST endpoints for project and API key management have their own separate rate limits. See [Temporary API Key Limits](/docs/create-additional-api-keys#temporary-api-key-limits) for details.
