Rate Limits

API Direct enforces concurrency limits to ensure fair usage and reliable performance for all users.

Concurrency Limit

Each user is limited to 3 concurrent requests per endpoint. This means you can have up to 3 in-flight requests to the same endpoint at the same time. Requests to different endpoints are counted separately.

For example, you can simultaneously make: - 3 requests to /v1/reddit/posts - 3 requests to /v1/twitter/posts - 3 requests to /v1/linkedin/posts

429 Response

If you exceed the concurrency limit, you’ll receive a 429 status code:

{
  "error": "Too many concurrent requests for this endpoint",
  "code": "concurrency_limit_exceeded"
}

Best Practices

Use sequential requests - For most use cases, sending requests one at a time is sufficient given the 1-2 second response times.

Queue your requests - If you need to make many requests, implement a queue that limits concurrency to 3 per endpoint.

Use the pages parameter - Endpoints like Twitter, YouTube, and Instagram support fetching multiple pages in a single request, reducing the total number of API calls needed.

Spread across endpoints - Concurrency limits are per-endpoint, so requests to different endpoints don’t count against each other.
