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 6 APIs on the APIs.io network, including Compliance API, Enrich API, Entitlement API, and 3 more. Tagged areas include Sales Intelligence, B2B, Enrichment, Contact Data, and GDPR.

Cognism’s developer surface includes authentication, support, pricing, signup flow, engineering blog, and 23 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cognism: open an issue to ask a question, or submit a pull request to add artifacts.

  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.

    (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
