GSK
GSK plc (formerly GlaxoSmithKline, rebranded in May 2022) is a global biopharma headquartered in the United Kingdom and dual-listed on the London Stock Exchange and NYSE under the ticker GSK. Following the July 2022 spin-off of its consumer-health business as Haleon, GSK is now a focused biopharma operating across four therapeutic areas — infectious diseases, HIV, oncology, and respiratory/immunology/inflammation — with flagship vaccine franchises including Shingrix and Arexvy and an HIV joint venture (ViiV Healthcare) held with Pfizer and Shionogi. GSK does not publish a public developer portal or commercial REST APIs. Machine-readable surfaces are limited to press, podcast and investor RSS feeds, the GSK Study Register and the ClinicalStudyDataRequest (CSDR) consortium portal for patient-level clinical trial data, registrations on ClinicalTrials.gov, and R/Python tooling published by the GSK-Biostatistics GitHub organization.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles GSK the way a machine reads it — 27 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — GSK scores 18.1/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

This is an independent, third-party profile of GSK, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
