Captain Data implements rate limits to ensure fair usage and optimal performance for all users.
Understanding these limits helps you design efficient automations and avoid interruptions.
Overview
Rate limits are applied at multiple levels:
- API Endpoints: Per-minute limits on specific API calls
- Daily Quotas: Total daily usage limits based on your plan
Each plan includes a daily quota that represents your total usage allowance. This quota is consumed by all API calls across your workspace.
Plan Tiers
Your rate limits are determined by your plan tier, which is based on your monthly credit allocation:
| Plan Tier | Monthly Credits | Description |
|---|
| Trial | Up to 1,000 | Free trial with basic limits |
| Bronze | 1 - 10,000 | Starter plans for small teams |
| Silver | 10,001 - 100,000 | Growing teams and businesses |
| Gold | 100,001 - 500,000 | Scaling businesses |
| Platinum | 500,001 - 2,000,000 | High-volume operations |
| Diamond | 2,000,001 - 20,000,000 | Large-scale enterprise |
| Titanium | 20,000,001 - 50,000,000 | Maximum enterprise scale |

API Rate Limits
Real-time Operations
The most important rate limits apply to API real-time operation execution.
These limits determine how many requests you can make per minute:
| Plan Tier | Max Requests/Second | Max Requests/Minute |
|---|
| Trial | 1 | 60 |
| Bronze | 2 | 120 |
| Silver | 10 | 600 |
| Gold | 10 | 600 |
| Platinum | 20 | 1,200 |
| Diamond | 20 | 1,200 |
| Titanium | 40 | 2,400 |
Capacity Examples
Assuming an average request duration of 2-3 seconds:
| Plan Tier | Estimated Daily Capacity | Example Use Case |
|---|
| Trial | ~86,400 requests/day | Small-scale testing |
| Bronze | ~172,800 requests/day | Individual prospecting |
| Silver / Gold | ~864,000 requests/day | Team sales operations |
| Platinum / Diamond | ~1,728,000 requests/day | Large-scale enrichment |
| Titanium | ~3,456,000 requests/day | Enterprise automation |
- Enrich ~864,000 people profiles per day
- Process ~36,000 profiles per hour
- Handle ~600 concurrent enrichment requests
Quotas
Rate limits for quota and billing data retrieval via /quotas:
| Plan Tier | Max Requests/Second | Max Requests/Minute |
|---|
| Trial | < 1 | 5 |
| Bronze | < 1 | 10 |
| Silver | 1 | 50 |
| Gold | 1 | 50 |
| Platinum | 1 | 75 |
| Diamond | 1 | 75 |
| Titanium | 2 | 100 |
Best Practices
Optimizing for Rate Limits
-
Implement Exponential Backoff: When you hit rate limits, wait before retrying with increasing delays.
-
Monitor Your Usage: Track your API consumption to stay within limits.
Handling Rate Limit Errors
When you exceed rate limits, you’ll receive a 429 Too Many Requests response.
{
"error": {
"code": 429,
"status": "Too Many Requests",
"details": {
"Retry-After": "60",
"X-RateLimit-Limit": "2",
"X-RateLimit-Reset": "1754402101",
"X-RateLimit-Type": "/v1/people/enrich"
},
"message": "Rate limit exceeded (/v1/people/enrich)"
}
}
This rate limit error response uses a different structure than our standard error format. For details on our typical error responses, see our
FAQ and Troubleshooting guide.

Getting Help
If you consistently hit rate limits or need higher limits:
- Review your implementation design for optimization opportunities
- Consider upgrading your plan for higher limits
- Contact support for custom enterprise solutions
