Cognism

Cognism is a B2B sales intelligence platform selling verified emails, mobile numbers, direct dials, firmographic and technographic data, buying-intent signals and contact enrichment to sales, marketing and RevOps teams, with a compliance-first posture built around GDPR and CCPA. Its API is a three-service REST contract published as a Postman collection at developers.cognism.com — a Search API for finding contacts and companies by filter, an Enrich API for matching records you already hold, and a Redeem API for exchanging the resulting redeem ID for the full profile. Search and Enrich return preview records and cost nothing; credits are consumed only when a contact is redeemed for the first time. A Compliance API exposes the opt-out suppression list, and an Entitlement API reports which fields the account is licensed to receive. API access is sales-gated: it must be enabled on the subscription, field-level entitlements provisioned by Cognism, and a six-month bearer token generated in the application.

Cognism publishes 1 API on the APIs.io network: Enrichment API. Tagged areas include Sales Intelligence, B2B, Enrichment, Contact Data, and GDPR.

Cognism’s developer surface includes authentication, support, pricing, signup flow, engineering blog, and 22 more developer resources.

  note: Documentation is fully public — the developer portal, the complete API reference and the help centre are all readable
    without an account. Access is not. API use requires the subscription to include API access (the Data-as-a-Service product,
    which itself requires a prospecting seat), field-level Entitlements provisioned by the Cognism team after Account Manager
    approval, and a token minted in the app. No prices, no free tier, no trial and no self-serve signup are published.

  headline: Found the real first-party contract. Cognism publishes its API as a Postman collection at developers.cognism.com
    (25 operations, published Production environment naming https://app.cognism.com as the base). Saved verbatim, converted
    to OpenAPI 3.1, and used to ground 16 artifacts. Also corrected the baseURL, replaced a dead developer-portal link, and
    removed a fabricated "conceptual" GraphQL schema that credited Cognism with an API it has never shipped.
x-coverage:
  state: covered
  reason: null
  detail: Contract discovery beat the JS-rendered docs host. developers.cognism.com is a Postman Documenter publication, not
    a spec site — the real, first-party, machine-readable Cognism API collection (25 operations, published Production environment)
    was pulled from documenter.gw.postman.com/api/collections/14862827/UVJhBu4C and converted to OpenAPI 3.1.
