4D Molecular Therapeutics (4DMT)
4D Molecular Therapeutics (4DMT) is a late-stage clinical biotechnology company headquartered in Emeryville, California, developing genetic medicines for large-market diseases. The company uses a proprietary directed-evolution platform it calls Therapeutic Vector Evolution to invent customized, proprietary adeno-associated virus (AAV) gene delivery vectors that carry therapeutic payloads to specific tissue types. Its pipeline targets retinal and pulmonary disease, led by 4D-150 for wet age-related macular degeneration and diabetic macular edema, and 4D-710 for cystic fibrosis lung disease. 4DMT is a therapeutics developer rather than a software vendor: it publishes no public API, developer portal, SDK, or machine-readable API contract of any kind.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles 4D Molecular Therapeutics (4DMT) the way a machine reads it — 1 machine-readable artifact, 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 — 4D Molecular Therapeutics (4DMT) scores 9.8/100 (minimal), 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.
Why this profile is thin
4DMT is a clinical-stage gene therapy developer whose product is a drug, not software: its entire public site is 18 WordPress marketing pages (about, pipeline, technology, patients, careers, investors, contact) with no developer, docs, or API section anywhere in its sitemap, and the only machine-readable JSON on the domain is the CMS-default WordPress REST API at /wp-json, which is Automattic's contract running under 4DMT's name rather than an API 4DMT designed, documented, or offers to anyone.
This is an honest zero, not a gap in our research. 4D Molecular Therapeutics (4DMT) does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

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 4D Molecular Therapeutics (4DMT), 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.
