Flare Therapeutics
Flare Therapeutics is a clinical-stage biotechnology company headquartered at 400 Technology Square, Cambridge, Massachusetts, developing small-molecule precision medicines against transcription factors — a target class long considered undruggable. Its platform combines a "switch site" hypothesis with cell-based ligand discovery and chemoproteomics to find binding pockets on transcription factors that control cancer cell states. The company launched publicly in May 2021 with an $82 million Series A led by Third Rock Ventures, and closed an $85 million insider-led Series C on 30 June 2026 led by Third Rock Ventures and Nextech Invest with Pfizer Ventures, Boxer Capital, GordonMD Global Investments, Invus, Casdin Capital, Eli Lilly, Novartis, Agent Capital and Eventide Asset Management participating, appointing Anna Protopapas as Chief Executive Officer at the same time. Its clinical-stage lead FX-909 is a PPARG inverse agonist in advanced urothelial cancer; FX-111 is an androgen-receptor-directed program in prostate cancer that received FDA IND clearance ahead of a clinical start in the third quarter of 2026. Flare also runs a discovery collaboration with Roche on undrugged transcription factor targets in oncology. Flare Therapeutics operates no developer program and publishes no product API, developer portal or API documentation. The only machine-readable surface reachable without credentials is the WordPress REST content API behind www.flaretx.com, catalogued here.
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 Flare Therapeutics the way a machine reads it — 6 machine-readable artifacts across 1 API, 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 — Flare Therapeutics scores 30.9/100 (thin), with a separate agent-readiness read of 37/100 (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 Flare Therapeutics
Each block below is one kind of artifact we hold for Flare Therapeutics. 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 1
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.
Flare Therapeutics Content API
The anonymously readable WordPress REST content API behind www.flaretx.com — the 42-item corporate news archive, 14 corporate pages, a 419-item media library, the category taxon...
Open Collections 1
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).
Flare Therapeutics Content API
OPEN COLLECTIONPricing 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 six things the Kin Score reads for commercial clarity.
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.

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.

This is an independent, third-party profile of Flare Therapeutics, 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.
