3T Biosciences
3T Biosciences is a clinical-stage immunotherapy company based in South San Francisco, developing next-generation T-cell receptor (TCR) therapeutics for solid tumors and other immune-mediated diseases. Founded in 2017 on research from K. Christopher Garcia's lab at Stanford University, the company operates its proprietary 3T-TRACE (T-Cell Receptor Antigen and Cross-reactivity Evaluation) platform, which combines high-diversity yeast-display target libraries with active machine-learning to screen billions of protein fragments and identify novel shared TCR targets and specificities. 3T has raised a $40M Series A from Westlake Village BioPartners and Lightspeed Venture Partners and has struck cancer-immunotherapy collaborations with Boehringer Ingelheim worth up to $268M in milestones. This profile was surfaced as a portfolio company of CRV and enriched into the API Evangelist network; 3T publishes no public developer API, SDK, or specification surface.
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 3T Biosciences 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 — 3T Biosciences scores 12.3/100 (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.
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 3T Biosciences
Each block below is one kind of artifact we hold for 3T Biosciences. 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.
Security Posture 1
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.
