Rate limits are applied per organization (based on the API key's team). Limits scale with your credit pack.Per-plan limits#
| Plan | Burst (req/sec) | Sustained (req/min) |
|---|
| Free | 5 | 60 |
| Growth | 25 | 300 |
| Scale | 50 | 1,000 |
| Pro | 100 | 5,000 |
| Enterprise | 200 | 10,000 |
Burst limits prevent short spikes from overwhelming the system. Sustained limits cap your average throughput over a rolling 60-second window.Endpoint-specific overrides#
Some endpoint categories have tighter limits to protect resource-intensive services:Enrichment endpoints (POST:/api/enrich/*)#
| Plan | Sustained (req/min) |
|---|
| Free | 10 |
| Growth | 100 |
| Scale | 500 |
| Pro | 2,000 |
Bulk submit endpoints (POST:/api/bulk/*)#
| Plan | Burst (req/sec) | Sustained (req/min) |
|---|
| Free | 1 | 2 |
| Growth | 3 | 10 |
| Scale | 5 | 20 |
| Pro | 10 | 50 |
Enterprise plans have no endpoint-specific overrides — global limits apply.Every response includes rate limit headers:| Header | Description |
|---|
X-RateLimit-Limit | Maximum requests in the window |
X-RateLimit-Remaining | Requests remaining in the window |
X-RateLimit-Reset | Seconds until the window resets |
429 Too Many Requests#
When you exceed a rate limit, the API returns a 429 response with a Retry-After header:{
"statusCode": 429,
"error": "Too Many Requests",
"message": "Rate limit exceeded, please retry later",
"retryAfter": 45
}
The Retry-After value (in seconds) tells you when you can safely retry.Tips for staying within limits#
Use batch endpoints for large datasets instead of making many single requests. A single bulk submit counts as one request.
Respect Retry-After — back off for the indicated duration before retrying.
Implement exponential backoff for transient failures.
Poll batch status at reasonable intervals (every 5–10 seconds) rather than in a tight loop.
Monitor your usage via the X-RateLimit-Remaining header to adjust throughput before hitting limits.
Upgrade your plan if you consistently hit limits — higher packs come with significantly higher rate limits.
