Droplet Biosciences
Droplet Biosciences is a Cambridge, Massachusetts clinical-stage molecular diagnostics company, founded in 2021 by physician scientists and backed by The Engine Ventures, that has pioneered a lymph liquid biopsy platform for detecting molecular residual disease after cancer surgery. Rather than sampling blood, Droplet stabilizes and extracts lymphatic fluid from routine post-surgical drain material through a proprietary isolation process, yielding an analyte source in which circulating tumor DNA is present at substantially higher levels than in matched plasma. Its lead test, LymphDetect, is an ultra-sensitive tumor-informed ctDNA assay initially targeting HPV-independent head and neck squamous cell carcinoma, run out of the company's own CLIA-licensed laboratory. Droplet is a laboratory and assay company, not a software vendor: it publishes no developer program, no documentation, no SDK and no OpenAPI. The machine-readable endpoints catalogued here are not a product API — they are the WordPress REST API, an OAuth 2.0 authorization server and three Model Context Protocol endpoints emitted by plugins on the company's marketing site, all found live and callable on dropletbiosci.com during contract discovery on 2026-08-12.
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 Droplet Biosciences the way a machine reads it — 7 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 — Droplet Biosciences scores 24.8/100 (emerging), with a separate agent-readiness read of 27/100 (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 Droplet Biosciences
Each block below is one kind of artifact we hold for Droplet 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.
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.
Droplet Biosciences WordPress REST API
The WordPress core REST API served from the company's marketing site. It is live, anonymous for published content, and self-describing: the discovery document at /wp-json/ lists...
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERPricing 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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Droplet Biosciences, 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.
