Blitz API
Stands out: Company, people, jobs, and TAM endpoints with no per-record fee, up to 15 million results a month.
Watch out: Work emails start on Plus at $499/mo. US phones sit only on Full at $599/mo. Fair use caps results at 15 million a month.
Not the right fit for
- SDR teams that only need a cheap email finder
- Products that must embed Blitz for end users under $399
Coresignal
Stands out: A real data API plus MCP at $49 Mini: this is enrichment infrastructure, not a Chrome overlay.
Watch out: Mini is 2,500 credits. Starter is $199 and Pro $499. Treating $49 as production volume will fail in week two.
Not the right fit for
- Recruiters who only want a LinkedIn Chrome finder
- Teams that need a sequencer
- Buyers who need ZoomInfo-the-UI
