About this repository

This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.

Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema, apis.json, llms.txt and similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.

The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.

Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.

• Something wrong? Open an issue on this repository, or email info@apievangelist.com.
• Published something new? Ask for a re-score and we will re-run the rating.
• Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.

Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.

On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.

Full detail: Where this data comes from

3GPP (the 3rd Generation Partnership Project) is the global standards partnership that writes the technical specifications for mobile networks — GSM, UMTS, LTE, 5G and the ongoing 6G work — through seven regional Organizational Partners (ARIB, ATIS, CCSA, ETSI, TSDSI, TTA and TTC) and a membership of operators, vendors and chipset makers. It is not a service provider and sells nothing to developers; it sits at the very top of the telecom value chain, defining the network functions that every mobile operator on earth deploys and that every CPaaS aggregator ultimately resells. Its API posture is unusually open for a standards body: all 3GPP specifications are published free of charge with no membership or login, and since Release 15 the RESTful Service-Based Architecture, the SCEF/NEF northbound exposure APIs and the SA5 management services have been published as machine-readable OpenAPI 3.0 YAML in a public GitLab instance at forge.3gpp.org. What 3GPP does not run is a developer programme — there is no portal, no key, no sandbox and no callable endpoint; the specifications describe interfaces that operators instantiate, and the developer-facing abstraction over them is CAMARA and GSMA Open Gateway, not 3GPP itself.

Developer Surface — an honest reading

3GPP runs no developer portal. developer.3gpp.org, developers.3gpp.org and docs.3gpp.org do not resolve; api.3gpp.org returns 404; www.3gpp.org/developer returns 200 but is an ordinary CMS content page with no signup, no key, no sandbox and no console. There is nothing to call: every base URL in every specification below is a template ({apiRoot}, {nrfApiRoot}) because 3GPP defines interfaces that mobile operators instantiate.

What 3GPP does do — and it is the opposite of most standards bodies in telecom — is give everything away. Technical specifications are published free of charge four times a year with no membership and no login (https://www.3gpp.org/ftp/Specs/archive/ served a full spec ZIP anonymously at review time), and the RESTful APIs inside those specifications are mirrored as machine-readable OpenAPI 3.0 YAML in a public GitLab at forge.3gpp.org. Membership buys a vote, not the output.

116 OpenAPI documents were harvested verbatim from two public 3GPP Forge repositories and all 116 parse as valid OpenAPI 3.0.0/3.0.1 — 72 from all/5G_APIs at REL-20 (TS 29.122 T8/SCEF, TS 29.222 CAPIF, TS 29.522 5G NEF northbound) and 44 from sa5/MnS at Rel-19 (SA5 management services). 214 paths in total; 43 documents declare OpenAPI callbacks (the subscribe/notify pattern that carries network events); 63 declare an OAuth 2.0 client-credentials security scheme with an NRF-issued token URL.

CAMARA posture

Underlying standard, not an implementer. 3GPP publishes no CAMARA API and exposes nothing callable. It writes the layer beneath: CAMARA's Quality on Demand abstracts 3GPP TS29122_AsSessionWithQoS, and the device location/status families abstract TS29122_MonitoringEvent — both harvested here as the underlay, not as CAMARA implementations. The only CAMARA reference on 3gpp.org is a first-party statement that CAPIF is designed to host non-3GPP APIs "defined by other SDO or consortiums such as ETSI ISG MEC, TM Forum, CAMARA, etc." 3GPP is not a GSMA Open Gateway participant — Open Gateway is an operator commitment programme, and GSMA sits in 3GPP as a Market Representation Partner, not one of the seven Organizational Partners (ARIB, ATIS, CCSA, ETSI, TSDSI, TTA, TTC). CIBA does not appear anywhere in the harvested specifications; 3GPP's consent mechanism is CAPIF RNAA (Resource owner-aware Northbound API Access, Rel-18).

All 116 entries below point at a specification 3GPP publishes openly. None is a hosted, callable service.
