A2 Biotherapeutics

A2 Biotherapeutics (A2 Bio) is a clinical-stage biotechnology company headquartered in Agoura Hills, California, founded in 2018 by Alexander Kamb, Michael Gallo and Paul Kang. It develops logic-gated cell therapies for solid tumors on its proprietary Tmod platform, a two-receptor activator/blocker design that lets an engineered T cell attack tumor cells which have lost an HLA allele while sparing normal cells that retain it. A2 Bio operates no developer API programme and publishes no product, clinical or research API. It is catalogued here because its corporate website runs a live WordPress REST API with 298 discoverable routes, and because that same install exposes two Model Context Protocol servers guarded by an OAuth 2.1 authorization server the host advertises through RFC 8414 and RFC 9728 metadata.

A2 Biotherapeutics publishes 5 APIs on the APIs.io network, including MCP API, Oembed/1.0 API, Root API, and 2 more. Tagged areas include Company, Biotechnology, Life Sciences, Cell Therapy, and Immuno-Oncology.

A2 Biotherapeutics’ developer surface includes engineering blog, authentication, and 25 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/a2-biotherapeutics: open an issue to ask a question, or submit a pull request to add artifacts.
