EDITOR'S VERDICT

Captain Data is the right API for engineers and technical GTM teams building AI agents, SaaS features, or enrichment pipelines that need structured B2B data with MCP support. Not for non-technical teams: no prospecting UI, pricing in EUR on a variable credit model, and no multi-provider waterfall fallback.

FAQs

4 questions before you build

QWhat is a Captain Data credit and how many do common operations consume?

One credit = one record processed. People Enrichment on a single URL uses 1 credit, returned in under 3 seconds. Find Employees returns multiple records, each consuming one credit: verify per-endpoint consumption in the API reference before running bulk jobs.

QHow does the interactive demo work before purchasing?

Demos run live against production endpoints, not a sandbox. Submit a real LinkedIn URL or company domain to see actual returned data. This validates field coverage and accuracy on your own targets before committing to a volume tier.

QWhen should I use Captain Data instead of Clay?

Use Captain Data for a clean B2B API with MCP integration inside AI agents or custom apps. Use Clay when you need 150+ provider waterfall coverage, Claygent AI research, or a no-code enrichment workflow UI.

QIs Captain Data GDPR compliant for EU B2B data?

Yes: SOC 2 certified and GDPR compliant. Teams with sector-specific obligations beyond standard GDPR should verify current data processing terms directly with Captain Data before scaling.

Bottom Line

Should you use Captain Data?

Use Captain Data for AI agents or enrichment pipelines that need structured B2B data via API with MCP support. Pass if you need a no-code prospecting UI, waterfall coverage, or fixed USD pricing: Clay, Apify, and PhantomBuster each address one of those gaps. Verify intermediate pricing and EUR conversion at captaindata.co before committing to a volume tier.
