Cellarity
Cellarity is a Somerville, Massachusetts based clinical-stage biotechnology company founded in 2017 inside Flagship Labs by Flagship Pioneering, which discovers medicines against the cell as a whole rather than a single molecular target. Its multi-omics, AI-powered platform is trained on tens of millions of single-cell transcriptomes to characterize disease as a shift in cell state and to design small molecules that course-correct that state back toward health. The company has raised roughly $294M across Series A, B and C rounds from Flagship Pioneering, BlackRock, The Baupost Group and Pictet Group, runs an active MASH collaboration with Novo Nordisk, and is advancing CLY-124 — a first-in-class globin-switching oral medicine for sickle cell disease — through a Phase 1 clinical study, alongside myelofibrosis and exploratory hematology programs. Cellarity publishes no product or developer API and runs no developer program; its only anonymously readable machine-readable surface is the WordPress REST API (wp/v2) that serves cellarity.com — news items, the drug-development pipeline, leadership and board profiles, event speakers, case studies, platform videos, media and site search — as JSON. Its scientific software is published as open-source research code in the github.com/Cellarity organization (DrugReflector, DILImap, MolRL), and its technical documentation site at docs.cellarity.com is a private Read the Docs Business instance behind SSO.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Cellarity the way a machine reads it — 36 machine-readable artifacts across 16 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 — Cellarity scores 22.9/100 (emerging), with a separate agent-readiness read of 29/100 (agent aware). 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 Cellarity
Each block below is one kind of artifact we hold for Cellarity. 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 16
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.

Security 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 Cellarity, 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.
