Cognism API
Cognism documents its REST API at developers.cognism.com covering contact and account search, preview, and enrichment. Access is plan-gated: API tokens are self-serve in the app, but only on Platinum and above, and usage is credit-metered. A legacy Prospector API is being phased out.

Cognism scores A on Supergood's API Report Card. Cognism documents its REST API at developers.cognism.com covering contact and account search, preview, and enrichment. Access is plan-gated: API tokens are self-serve in the app, but only on Platinum and above, and usage is credit-metered. A legacy Prospector API is being phased out.
Cognism has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Cognism is a B2B sales intelligence and contact data platform headquartered in London (with hubs in New York, Boston, and Singapore) that supplies verified emails, mobile phone numbers, firmographics, technographics, intent signals, and account targeting recommendations to revenue teams.
Primary vertical: misc (cross-industry B2B sales intelligence / GTM tooling). An SDR opens the Cognism web app or Chrome extension on a LinkedIn profile, reveals a Diamond-verified mobile number and work email, and one-click pushes the contact into Salesforce or HubSpot with the verified-mobile field mapped.
High in the EMEA B2B GTM segment, mid-to-high globally.
Cognism is the contact-and-signal layer feeding pipeline generation for EMEA-strong B2B revenue teams. API responses populate Salesforce / HubSpot / Dynamics lead and contact records, drive Outreach / Salesloft sequences, and route intent and signal events into RevOps automation.
Founded in 2015 by James Isilay (current CEO), with Series A in 2018, Series B in 2019, Series C in 2022 (raising ~$87.5M at a reported ~$700M valuation, led by Viking Global). Acquired Mobilead (compliance) in 2020 and Kaspr (LinkedIn extension) in 2022.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official Cognism MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Cognism doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
