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 API contracts indexed 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.

The Owler catalog on APIs.io includes 1 Spectral governance ruleset.

Owler’s developer surface includes engineering blog, support, pricing, documentation, API reference, and 24 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)

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 the provider profile at artifacts.apis.io/owler/apis.yml: open an issue on github.com/api-evangelist/owler to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Surveys, Market Research and Experience Management	standard	34.5 (thin)	-	-
APIs.guru OpenAPI Directory (API definition directory)	standard	34.5 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
