Adcendo

Adcendo ApS is a clinical-stage biopharmaceutical company headquartered in Copenhagen, Denmark, with US operations in Boston, Massachusetts, developing a new generation of antibody-drug conjugates (ADCs) for cancers with high unmet medical need. Founded in 2017 out of research by Lars Henning Engelholm and Niels Behrendt, the company advances a clinical and pre-clinical pipeline that includes ADCE-T02 (targeting Tissue Factor, in the Phase 1b Tiffany-01 study across advanced solid tumors), ADCE-D01 (targeting uPARAP, granted FDA Fast Track designation for soft tissue sarcoma), and the pre-clinical ADCE-B05. Adcendo is a privately held, venture-backed therapeutics developer; it publishes a corporate website, pipeline and publications pages, and investor press releases, but it operates no developer program, public API, or machine-readable API contract.

Adcendo is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Oncology, and Life Sciences.

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/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

13 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Developer Ergonomics scores 0.0 — up to +20.0 composite points
Access Clarity scores 10.5 — up to +17.9 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/adcendo/apis.yml: open an issue on github.com/api-evangelist/adcendo to ask a question or point us at an artifact you publish.
