Rate Limits

Octen enforces rate limits to ensure platform stability and fair usage across all customers. Rate limits define how frequently you can call the API within a given time window. Requests that exceed these limits will be temporarily rejected.

​

Search API, Embedding API & VL Embedding API

The following QPS (Queries Per Second) limits are shared across the Search API, Embedding API, and VL Embedding API:

​

How rate limits are applied

Rate limits are determined by your account plan and optional per-key caps:

• Each account has a default rate limit based on its subscription tier.
• When creating an API key, you may configure an additional rate limit for that key.
• If both are configured, requests are throttled by whichever limit is lower (account or API key).
• Different APIs may have different rate limits.
• Limits may vary depending on your usage tier or agreement.

​

Extract

The Extract API uses a rate limiting model based on requests per minute (RPM):

​

Web Chat & Broad Search

Web Chat and Broad Search use a rate limiting model based on requests per minute (RPM) and tokens per minute (TPM):

​

Deep Research

Only a single concurrent request is supported.

​

What happens when you exceed a limit

If a request exceeds the allowed rate:

• The request is rejected with a rate limit error.
• HTTP status: 429
• Response body: code=429 and msg includes the reason (account limit or API key limit) and the applicable rate limit.

​

Recommended retry behavior

When receiving a rate limit error:

• Check the msg for detail.
• Avoid immediate retries in a tight loop.
• Resume requests after the rate limit window resets.
• For high-throughput or bursty workloads, batching requests where supported can help reduce pressure on rate limits.

​

Monitoring your usage

You can monitor your usage through the platform, including:

• Request counts
• Tokens and content usage
• Total cost and daily cost

​

Increasing rate limits

If your application requires higher throughput or sustained traffic:

• Custom limits or enterprise plans may be available.
• Contact the Octen team to discuss your use case.
