Credits

Sarvam offers ₹100 worth of free credits for every user on signup. These credits can be used across any of our APIs — explore, prototype, and build without upfront cost.

Credits are universal and never expire. Once exhausted, add more credits or upgrade your plan from the Sarvam Dashboard.

How Rate Limits Work

Rate limits restrict the number of API requests your account can make within a given time window. Key points:

  • Per-account enforcement — limits apply to your account as a whole, not individual API keys. All keys share the same rate limit pool.
  • Continuous replenishment — capacity refills steadily over the window period rather than resetting all at once (token bucket model).
  • Per-API granularity — each API has its own independent rate limits. WebSocket, Vision, and LLM APIs have different limits from standard REST APIs — check your specific API below.

Per-API Rate Limits by Plan

Rate limits vary significantly by API type and plan. Review the limits for each API below before building your integration.

Speech to Text

Real-time REST (stt-rt)

StarterProBusiness
Rate Limit60 req/min100 req/min4,000 req/min

WebSocket Streaming (stt-ws)

StarterProBusiness
Rate Limit20 concurrent100 concurrent100 concurrent

Batch (stt-batch)

StarterProBusiness
Rate Limit20 req/min100 req/min500 req/min

For batch endpoints, implement a minimum 5ms delay between consecutive status polling requests to avoid hitting rate limits unnecessarily.

Text to Speech

Real-time REST (tts-rt)

StarterProBusiness
Rate Limit60 req/min200 req/min1,000 req/min

For bulbul:v3 model specifically, Starter rate limit is 30 req/min. Pro and Business limits are the same as the default above.

WebSocket Streaming (tts-ws)

StarterProBusiness
Rate Limit60 concurrent200 concurrent1,000 concurrent

For bulbul:v3 model specifically, Starter rate limit is 30 concurrent. Pro and Business limits are the same as the default above.

Translation & Text Services

Chat Completion (LLM)

Default models (ms-llm)

Sarvam-30B & Sarvam-105B models

These large models have lower limits due to their compute requirements.

StarterProBusiness
Rate Limit40 req/min60 req/min120 req/min

Applies to: sarvam-30b, sarvam-105b

Vision

Vision API limits are uniform across all plans (Starter, Pro, and Business). Upgrading your plan does not increase Vision limits.

Document Intelligence (vis-doc-dig)

Rate limits are measured per account, not per API key. All keys under an account share the same limit pool. Your current limits are visible on the Dashboard → Rate Limits page.

Upgrading Your Limits

1

Enterprise & Custom Limits

Need higher rate limits, dedicated infrastructure, or custom SLAs? Talk to our team.

Managing Your Credits

If your credits are exhausted, API requests will return errors. You can add credits at any time — adding credits does not change your plan or rate limits.

  1. Add Credits — Top up from the Billing page at any time. Credits never expire.
  2. Upgrade Your Plan — Higher plans include bonus credits and increased rate limits.
  3. Enterprise — For volume discounts and custom billing arrangements, email developer@sarvam.ai.
