Harbinger Health
Harbinger Health is a Cambridge, Massachusetts biotechnology company founded out of Flagship Pioneering's Flagship Labs in 2018 that is building blood-based early cancer detection on the premise that the earliest phases of oncogenesis are marked by the reactivation of core developmental programs. Its proprietary Harbinger HX platform pairs cell-free DNA methylation assay chemistry tuned for low tumour fraction with machine learning operating under biologically informed constraints, and supports cancer signal detection, tumour content estimation and tissue-of-origin inference. RESOLVE, the company's clinical application of that platform, is positioned to generate clarity in the uncertain window between suspicion of cancer and diagnosis, across cancer types and clinical contexts, and is run out of a CLIA-certified and CAP-accredited high-complexity laboratory. The company raised a 100 million dollar round to expand its blood-based detection suite and is led by CEO Ajit Singh with Chief Innovation Officer Tony Shuber, a co-founder of Exact Sciences. Harbinger Health's API posture is minimal and clinical rather than commercial: there is no developer portal, no published documentation, no OpenAPI, no SDKs, no pricing and no self-serve API access, and the developer., docs., api., portal., status. and trust. subdomains do not resolve. What it does publish is unusual for a company with no developer programme - the corporate site serves a live, anonymously readable WordPress REST API (268 routes across 15 namespaces), an RFC 8414 OAuth 2.1 authorization-server metadata document, an RFC 9728 protected-resource document, and a real Model Context Protocol server namespace gated behind an mcp scope, alongside the WordPress Abilities API. That makes Harbinger Health machine-discoverable at the agent layer while none of its clinical, laboratory or diagnostic capability is exposed programmatically to third parties.
Harbinger Health publishes 36 APIs on the APIs.io network, including Block Directory API, Block Patterns API, Block Renderer API, and 33 more. Tagged areas include Health, Healthcare, Biotechnology, Cancer Detection, and Diagnostics.
Harbinger Health’s developer surface includes engineering blog, support, YouTube channel, authentication, code examples, and 31 more developer resources.
