Where they pull apart

Blitz API

Stands out: Company, people, jobs, and TAM endpoints with no per-record fee, and every plan opens every endpoint, including verified emails and US phones.

Watch out: Start caps fair use at 200,000 records a month and 10 requests per second per endpoint. Scale is $499/mo for 5,000,000 records. Phone endpoints need a paid plan, not the free records.

Not the right fit for

  • SDR teams that only need a cheap email finder
  • Products that must embed Blitz for end users under $2,000/mo

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
