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.

Droplet Biosciences publishes 1 API on the APIs.io network. Tagged areas include Company, Health, Healthcare, Diagnostics, and Oncology.

Droplet Biosciences’ developer surface includes authentication and 19 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/droplet-biosciences: open an issue to ask a question, or submit a pull request to add artifacts.

  description: '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 472 routes across 19 namespaces, and the wp/v2
    namespace (138 routes) serves Droplet''s own content including the custom post types publications, press-releases and
    team. This is a CMS default surface, NOT a Droplet product API — there is no documentation, no portal, no plan, no support
    channel and no versioning or deprecation policy attached to it. It is catalogued because it genuinely exists and an agent
    can call it. The same host also exposes an OAuth 2.0 authorization server and three Model Context Protocol endpoints under
    /wp-json/, which are gated and covered by the artifacts below.'

x-enrichment-note: 'Supersedes the earlier 2026-08-12 pass that recorded status minimal / x-coverage none:no-developer-program.
  That pass probed only the site root and concluded there was no machine-readable interface. Contract discovery against /wp-json/
  found a live anonymous REST API, an OAuth 2.0 authorization server with PKCE and open dynamic client registration, and three
  MCP endpoints. The x-coverage block has been removed because the profile is no longer thin — but note that Droplet still
  has NO developer program, and the surfaces found are CMS/plugin byproducts rather than a product API. Read mcp/droplet-biosciences-mcp.yml
  and well-known/droplet-biosciences-well-known.yml before treating Droplet Biosciences as an API provider. No WellKnown,
  SecurityTxt, AgentCard, Idempotency, SDKs, StatusPage, Deprecation, Security or TrustCenter pointer is emitted: every one
  of those probes returned a verified miss.'
