Owler

Owler is a crowdsourced competitive- and business-intelligence platform that maintains real-time profiles on more than 20 million public and private companies, tracking firmographics, funding, and news across 45M+ competitive relationships contributed and validated by a community of 5M+ business professionals. It is delivered as web and mobile apps (Owler Community, Pro, and Max), a Chrome extension, and CRM and collaboration integrations (Salesforce, HubSpot, Slack, Microsoft Teams, ChatGPT). The Owler Enterprise API is a real, publicly documented REST API: a Swagger UI developer portal at developers.owler.com renders an OpenAPI 3.0.1 definition (six read operations across Company Premium, Competitor Premium and Feed, served from https://apiv2.owler.com, authenticated with an x-api-key header) that is fetchable at https://developers-v3.owler.com/apis/api3-swagger.json. Access to the data itself is sold through the data-licensing sales motion rather than self-serve signup, and Owler ships no first-party SDKs, CLI or MCP server. Owler was acquired by Meltwater in 2021. Added to the API Evangelist network from the Norwest Venture Partners portfolio.

Owler publishes 3 APIs on the APIs.io network: Company Premium API, Competitor Premium API, and Feed API. Tagged areas include Company, Company Intelligence, Sales Intelligence, Competitive Intelligence, and Business Data.

Owler’s developer surface includes engineering blog, support, pricing, documentation, API reference, and 23 more developer resources.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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/owler: open an issue to ask a question, or submit a pull request to add artifacts.

  note: Contract discovery reversed the previous round's "no public developer API, no OpenAPI" finding. The developer portal
    at developers.owler.com is a Swagger UI on S3 whose subpaths all return 403; its index.html names the live spec URL https://developers-v3.owler.com/apis/api3-swagger.json,
    which serves a real OpenAPI 3.0.1 (HTTP 200, 52KB) — "Owler Enterprise API" v3.0, servers https://apiv2.owler.com, terms
    corp.owler.com/terms-conditions, contact "Owler Support". Ownership verified from the document's own servers[]/info block,
    not the fetch URL.
