§ · FAQ — common questions

QWhat data can I access through Captain Data APIs?›
Captain Data provides access to 750M+ professional profiles and 54M+ companies. You can enrich people and company profiles, search for prospects, find employees at companies, and more. All data is fetched in real-time to ensure freshness.
QHow accurate is the data?›
We maintain high accuracy across enrichment endpoints. Responses are fetched in real time from live professional sources, so you get current titles, companies, and firmographics rather than stale batch dumps.
QHow does the credit system work?›
Each API endpoint consumes credits based on the operation. Simple enrichments cost 1 credit, while search operations cost 1 request plus 1 credit per result returned. Unused credits do not roll over month to month. On annual billing, we can unlock your full yearly credit pool upfront.
QWhat's the difference between enrichment and search?›
Enrichment takes a known identifier (like a LinkedIn URL or company domain) and returns detailed data. Search allows you to find people or companies based on criteria like job title, location, industry, and more.
QCan I integrate these APIs with my existing tools?›
Yes! Our REST APIs work with any platform that can make HTTP requests. We also offer MCP integration for AI assistants and easy integrations with popular automation tools.
QWhat are the rate limits?›
Rate limits depend on your plan. Trial starts at 1 request/second, while higher plans include up to 40 requests/second, and Enterprise plans can be customized for higher throughput. Export endpoints (#soon) are available for bulk processing.
QIs the data GDPR compliant?›
Yes, Captain Data is SOC 2 Type II certified and fully GDPR compliant. We only collect publicly available professional data and provide mechanisms for data subject requests. All data is encrypted at rest and in transit.
