Vendor's own claim

What it can do
Vendor's own claim- People and company search
- Profile enrichment
- Company intelligence
- Employee search with role filters
- Quota and credit checks
- MCP connection for AI assistants
Who it is for
Vendor's own claimAI-product and B2B SaaS teams that need one API to search and enrich people and company records at volume.
When to choose something else
Our readIt is a poor fit for teams with tiny, infrequent enrichment needs: the public pricing calculator's illustrated starting point is 20,000 credits at €29.99 per 1,000 (€600/month). It is also a poor fit if a team needs a vendor-published machine-readable API contract, which was not retrieved.
Implementation considerations
Our readSetup assessment: 30m
The documented API flow is to create an API key and make authenticated calls; the MCP page describes a hosted configuration plus the same key.
