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
  • Concurrent Execution: Limits on parallel automated runs and batch processing
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 TierMonthly CreditsDescription
Trial1,000Free trial with basic limits
Low2,500 - 10,000Starter plans for small teams
Mid10,000 - 500,000Growth plans for expanding businesses
High500,000 - 20,000,000Scale plans for high-volume operations
Highest20,000,000 - 100,000,000Enterprise plans for large organizations

​
API Rate Limits

​
Real-time Actions

The most important rate limits apply to real-time action execution via /v4/actions/{action-name}/run/live. These limits determine how many requests you can make per minute:
Plan TierMax Requests/SecondMax Requests/Minute
Trial160
Low2120
Mid10600
High201,200
Highest402,400
For async actions, different concurrent execution limits apply (see Concurrent Execution below).

​
Capacity Examples

Assuming an average request duration of 2-3 seconds:
Plan TierEstimated Daily CapacityExample Use Case
Trial~86,400 requests/daySmall-scale testing
Low~172,800 requests/dayIndividual prospecting
Mid~864,000 requests/dayTeam sales operations
High~1,728,000 requests/dayLarge-scale enrichment
Highest~3,456,000 requests/dayEnterprise automation
Example: With a Mid tier plan (600 requests/minute), you can:
  • Enrich ~864,000 LinkedIn profiles per day
  • Process ~36,000 profiles per hour
  • Handle ~600 concurrent enrichment requests

​
Identity Management

Rate limits for identity-related operations via /v4/identities (create, update, delete, retrieve):
Plan TierMax Operations/SecondMax Operations/Minute
Trial2100
Low2100
Mid4250
High5300
Highest8500

​
Capacity Examples

For identity operations (create, update, delete):
Plan TierDaily CapacityUse Case
Trial~144,000 operations/dayBasic account management
Low~144,000 operations/daySmall team setup
Mid~360,000 operations/dayGrowing organization
High~432,000 operations/dayLarge team management
Highest~720,000 operations/dayEnterprise identity management

​
Workspace Info

Rate limits for workspace data retrieval via /v4/workspaces:
Plan TierMax Requests/SecondMax Requests/Minute
Trial< 15
Low< 110
Mid150
High175
Highest2100

​
Concurrent Execution

For async runs via /v4/actions/{action-name}/run/async, we limit the number of concurrent runs and batch processing:
Plan TierMax Concurrent RunsMax Batches per Run
Trial/Low22
Mid53
High105
Highest158

​
Capacity Examples

For async automations with concurrent execution:
Plan TierEstimated Daily CapacityUse Case
Trial/Low~50,000-100,000 records/dayBasic automation
Mid~200,000-500,000 records/dayTeam automations
High~500,000-1,000,000 records/dayLarge-scale automation
Highest1,000,000+ records/dayEnterprise automations
Example: With a High tier plan (10 concurrent runs, 5 batches each):
  • Process ~500,000-1,000,000 records per day
  • Handle complex automations with large results
  • Scale to enterprise-level automation needs

​
Best Practices

​
Optimizing for Rate Limits

  1. Use Async Mode for High Volume: When processing large datasets, use async mode to benefit from concurrent execution limits rather than hitting real-time rate limits.
  2. Batch Your Requests: Group related operations together to minimize API calls.
  3. Implement Exponential Backoff: When you hit rate limits, wait before retrying with increasing delays.
  4. 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_label": "<string>",
  "error_scope": "input",
  "error_ref": "ERR-12345",
  "message": "You have been rate limited.",
  "status_code": 429,
  "params": {}
}

​
Plan-Specific Considerations

​
Free and Low Tiers

  • Focus on development and testing
  • Use async mode for production workloads
  • Monitor usage closely to avoid interruptions

​
Mid and High Tiers

  • Suitable for production workloads
  • Balance between real-time and async execution
  • Consider upgrading for higher volume needs

​
Highest Tier

  • Designed for enterprise-scale operations
  • Maximum concurrent execution capabilities
  • Contact support for custom limits if needed

​
Monitoring and Alerts

Track your rate limit usage through:
  • API response headers
  • Dashboard analytics
  • Webhook notifications for quota warnings

​
Getting Help

If you consistently hit rate limits or need higher limits:
  1. Review your implementation design for optimization opportunities
  2. Consider upgrading your plan for higher limits
  3. Contact support for custom enterprise solutions
