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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles IgGenix the way a machine reads it — 19 machine-readable artifacts across 14 APIs, 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 — IgGenix scores 29.9/100 (thin), with a separate agent-readiness read of 45/100 (agent ready). 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.

How we profile IgGenix
Each block below is one kind of artifact we hold for IgGenix. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 14
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Iggenix Rate Limits
RATE LIMITSSecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of IgGenix, 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.
