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
DiscoLike
Stands out: Every plan includes the full search set, REST, SDK, CLI, and MCP; you pay for volume, not features.
Watch out: Your subscription converts to credits, and each search costs a query fee plus a fee for new records. Embedding data in a customer-facing product needs Enterprise.
Not the right fit for
- Buyers who want a cheap email-finder UI, not a search budget
- Products that will resell company data without Enterprise
