# Migrating from ElevenLabs: Overview

> Common setup changes for teams moving from ElevenLabs to Sarvam: base URL, auth header, SDK client, and error handling, shared across every guide in this section.

*Last updated: July 15, 2026*

This page covers the setup changes that stay the same no matter which of your existing ElevenLabs integrations you're moving over: base URL, auth header, and SDK client. Each product-specific migration guide already includes these same changes inline, so you don't need to read this page first; it's here as a standalone reference if you want the setup changes on their own.

## Quick start

Swap the client, then keep the rest of your code as-is:

#### Before (ElevenLabs)

```python
from elevenlabs import ElevenLabs

client = ElevenLabs(api_key="YOUR_ELEVENLABS_API_KEY")
```

#### After (Sarvam)

```python
from sarvamai import SarvamAI

client = SarvamAI(api_subscription_key="YOUR_SARVAM_API_KEY")
```

Both SDKs are also available for TypeScript/JavaScript; see [SDKs & Libraries](/api/getting-started/sdks) for install instructions and language coverage.

For requests made directly over HTTP rather than through an SDK, the only change is the header and base URL:

#### Before (ElevenLabs)

```bash
curl -X POST "https://api.elevenlabs.io/v1/..." \
  -H "xi-api-key: YOUR_ELEVENLABS_API_KEY"
```

#### After (Sarvam)

```bash
curl -X POST https://api.sarvam.ai/... \
  -H "api-subscription-key: YOUR_SARVAM_API_KEY"
```

## Base URL and auth

|                     | ElevenLabs                  | Sarvam                  |
| ------------------- | --------------------------- | ----------------------- |
| Base URL            | `https://api.elevenlabs.io` | `https://api.sarvam.ai` |
| Auth header         | `xi-api-key`                | `api-subscription-key`  |
| Auth failure status | `401`                       | `403`                   |

## Errors and rate limits

Sarvam returns `403` (not `401`) on authentication failures, and rate limits are enforced per API rather than account-wide. See [Errors & Troubleshooting](/api/getting-started/errors-troubleshooting) and [Credits & Rate Limits](/api/getting-started/ratelimits) for status codes and retry behavior. These apply the same way across every migration guide in this section.
