IgGenix

IgGenix, Inc. is a clinical-stage antibody discovery and development company in South San Francisco, California, founded in 2019 on work from Stephen Quake's laboratory at Stanford in collaboration with allergy clinician-researcher Kari Nadeau. Its SEQ SIFTER platform uses single-cell RNA sequencing to capture the rare IgE-producing B cells circulating in allergic patients' blood, then re-engineers those sequences into fully human, high-affinity, allergen-specific IgG antibodies designed to block the allergic cascade before it starts. Lead program IGNX001 is a human IgG4 monoclonal antibody for peanut allergy, in the Phase 1 ACCELERATE Peanut trial, with discovery programs against alpha-gal syndrome, nsLTP allergens and atopic dermatitis autoantigens. The company has raised roughly $75M across seed, Series A and a $40M Series B. IgGenix publishes no product or developer API and no developer program; the only machine-readable surface on iggenix.com is the WordPress REST API (wp/v2) served at https://iggenix.com/wp-json/, which returns the company's press releases, peer-reviewed publications, conference abstracts, careers post type, pages, media library, taxonomies and site search as anonymous JSON. The OpenAPI definitions in this repository were derived mechanically from that route index; IgGenix publishes none of its own.

IgGenix publishes 1 API on the APIs.io network. Tagged areas include Company, Biotechnology, Life Sciences, Immunology, and Allergy.

IgGenix’s developer surface includes support, authentication, code examples, and 20 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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