Ofcom

Ofcom is the Office of Communications, the United Kingdom's independent regulator and competition authority for telecommunications, spectrum, broadcasting, post, and online safety. It licenses UK spectrum, administers the national numbering plan, publishes the Connected Nations reports on fixed and mobile coverage, and supervises the operators (EE, VMO2, Vodafone, Three) rather than selling connectivity itself. Its position in the telecom value chain is therefore upstream of the market it measures — it is a data producer and rule-setter, not a network or a CPaaS aggregator. Its API posture is unusually good for a regulator and unusually narrow in scope. Ofcom runs a real, Ofcom-branded Azure API Management developer portal at api.ofcom.org.uk with open sign-up, an interactive console, published rate-limit tiers, and anonymously downloadable OpenAPI 3.0.1 documents for two APIs — the Connected Nations Broadband API and the Connected Nations Mobile API — both served from the live gateway at api-proxy.ofcom.org.uk and authenticated with an Azure APIM subscription key. Everything else Ofcom publishes (spectrum licence registers, numbering data, market research) is documents and datasets, not APIs, and the community has repeatedly built third-party APIs on top of those files. Ofcom appears once in the CAMARA project participant register but exposes no CAMARA network APIs and is not a GSMA Open Gateway participant — Open Gateway is an operator commitment programme and Ofcom is the regulator, not an operator.

Ofcom publishes 1 API contract indexed on the APIs.io network: Coverage API. Tagged areas include Telecommunications, United Kingdom, Regulator, Broadband, and Mobile Network Coverage.

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

Ofcom’s developer surface includes sandbox, authentication, documentation, signup flow, API reference, developer console, support, and 27 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications 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

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)
