A-Alpha Bio

A-Alpha Bio is a Seattle biotechnology company, founded in 2017 out of the University of Washington's Institute for Protein Design and Center for Synthetic Biology, that measures, predicts and engineers protein-protein interactions. Its experimental platform AlphaSeq reprograms yeast mating to quantify millions of protein-protein binding affinities in a single experiment, and its computational platform AlphaBind is a domain-specific deep-learning model trained on hundreds of millions of those affinity measurements to predict and optimize antibody-antigen binding from sequence. In July 2026 the company launched Atlas, a web platform and data ecosystem that publishes ML-ready protein interaction "Data Blocks" for licensing, custom on-demand data generation, and a quarterly-release Atlas Consortium whose founding members include GSK, Boltz, Cradle and Dyno Therapeutics. Atlas is backed by a public HTTP API — the Data Product API at api.atlas.aalphabio.com — which serves dataset discovery, dataset metadata and structured Data Cards anonymously, and gates CSV data, CSV schemas and structure (.cif) files behind a bearer token issued through AWS Cognito sign-in.

A-Alpha Bio publishes 1 API on the APIs.io network: Datasets API. Tagged areas include protein-interactions, Biotechnology, Drug Discovery, Antibody Engineering, and Synthetic Biology.

A-Alpha Bio’s developer surface includes signup flow, engineering blog, product news, support, authentication, CLI, and 24 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 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/.
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/a-alpha-bio: open an issue to ask a question, or submit a pull request to add artifacts.
