Dragonfly Therapeutics

Dragonfly Therapeutics is a clinical-stage biotechnology company based in Waltham, Massachusetts, founded in 2016 by Tyler Jacks, Bill Haney and David Raulet to develop natural killer (NK) cell-based immunotherapies. Its proprietary TriNKET (Tri-specific NK cell Engager Therapy) and cytokine engager platforms produce molecules that bind both a tumor or disease antigen and an NK cell activating receptor, recruiting innate and adaptive immunity against cancer, autoimmune disease, fibrosis and neuro-inflammation. Lead clinical candidate DF1001 targets HER2 in advanced solid tumors, and the platform is licensed under multi-target collaborations with AbbVie, Bristol Myers Squibb, Merck and Gilead. Dragonfly is a therapeutics developer rather than a software company: it publishes no developer program, no public API, no SDKs and no machine-readable API contract. The only agent-readable surfaces on its own host are the llms.txt and Model Context Protocol endpoint automatically provisioned by its Wix website platform.

Dragonfly Therapeutics is listed with 1 API on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Immunotherapy, and Oncology.

Dragonfly Therapeutics’ developer surface includes engineering blog, product news, authentication, 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.

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
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

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/dragonfly-therapeutics/apis.yml: open an issue on github.com/api-evangelist/dragonfly-therapeutics to ask a question or point us at an artifact you publish.
