Kallyope, Inc. is a New York City clinical-stage biotechnology company, founded in 2015 by Columbia University scientists Charles Zuker, Tom Maniatis and Richard Axel, that translates the biology of the gut-brain axis into medicines. It launched with a $44M Series A and has since raised a $66M Series B, a $112M Series C and a $236M Series D co-led by Mubadala Investment Company and The Column Group, with backers including Bill Gates, Lux Capital, Polaris Partners, Casdin Capital and Alexandria Real Estate Equities. Its proprietary Klarity platform integrates single-cell sequencing, pathway circuit mapping, optogenetics and chemogenetics, proprietary human genetics, mouse and human organoid systems, and small-molecule and peptide chemistry to map the neural circuits underlying migraine and metabolism; lead candidate elismetrep, a TRPM8 blocker, is in Phase 3 development for acute migraine. Kallyope publishes no developer portal, API reference, SDKs, CLI, status page or public GitHub organization, and no OpenAPI, AsyncAPI, GraphQL, MCP or A2A agent-card surface was found on any host. Enrichment probing did find one real, anonymous, read-only REST surface: kallyope.com runs WordPress and exposes the WordPress REST API publicly at https://kallyope.com/wp-json, carrying the company news feed, site pages, media library and a first-party "document" content type of scientific posters, presentations and publications classified by the custom program, event, content-type and document-type taxonomies.
Kallyope publishes 1 API on the APIs.io network: Content REST API. Tagged areas include Company, Biotechnology, Life Sciences, Pharmaceuticals, and Drug Discovery.
The Kallyope catalog on APIs.io includes 1 JSON-LD context.
Kallyope’s developer surface includes engineering blog, support, and 11 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.
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/.

description: 'Anonymous, read-only REST surface behind kallyope.com. Kallyope runs WordPress and exposes the WordPress REST
API publicly at https://kallyope.com/wp-json with 326 registered routes across 14 namespaces. The publicly readable surface
is the stock wp/v2 namespace, which Kallyope has extended with a first-party custom post type — "document" (scientific
posters, presentations, publications and video) — and four first-party custom taxonomies that classify it: program (drug
programs, e.g. elismetrep), event (scientific congresses such as the American Headache Society and Academy of Neurology
annual meetings), content-type (presentation, poster, publication, video, terms-conditions) and document-type. Alongside
those sit the core posts (company news), pages, media, categories, users, search, types and taxonomies collections. No
authentication is required for reads and none of the write methods are reachable anonymously; no API keys, rate-limit
headers or developer documentation are published for it. This is a content and marketing API, not a Klarity platform,
research-data or clinical API.'
