Mercy BioAnalytics
Mercy BioAnalytics, Inc. is a Waltham, Massachusetts clinical-stage cancer diagnostics company, founded in 2018, developing extracellular-vesicle (EV) based liquid biopsy tests for the early detection of cancer. Its patented Mercy Halo platform uses biomarker co-localization — the simultaneous detection of multiple cancer-related biomarkers on the surface of individual tumor-derived extracellular vesicles — to read a small volume of serum or plasma with a simple PCR-based readout. The company's initial programs target ovarian cancer screening in asymptomatic post-menopausal women and lung cancer detection in average and high-risk individuals; the Mercy Halo Ovarian Cancer Screening Test received FDA Breakthrough Device Designation in May 2024. Mercy BioAnalytics raised a $41M Series A in April 2023 led by Novalis LifeSciences and a $59M Series B in September 2025. The product is a laboratory-developed blood test, not software: as of this profile the company publishes no public developer program, API, SDK, or machine-readable API contract of any kind.
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 Mercy BioAnalytics 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 — Mercy BioAnalytics scores 2.9/100 (minimal), with a separate agent-readiness read of 3/100 (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.
Why this profile is thin
Mercy BioAnalytics sells a lab-run blood test (the Mercy Halo extracellular-vesicle liquid biopsy), not software — no api/developer/docs/portal/app subdomain of mercybio.com resolves in DNS, no GitHub org exists under mercybio or mercy-bioanalytics, no package is published to npm or PyPI, and every /openapi, /graphql and /.well-known path on mercybio.com is answered by a 169-byte SiteGround `sg-captcha` interstitial (HTTP 202) rather than a document.
This is an honest zero, not a gap in our research. Mercy BioAnalytics does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Mercy BioAnalytics
Each block below is one kind of artifact we hold for Mercy BioAnalytics. 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.

This is an independent, third-party profile of Mercy BioAnalytics, 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.
