Photys Therapeutics

Photys Therapeutics is a clinical-stage biopharmaceutical company in Waltham, Massachusetts advancing proximity-based, targeted protein modulation medicines across three heterobifunctional modalities: PROTAC-based protein degradation (lead program PHT-776/HPB-143, an oral IRAK4 degrader that entered Phase I in August 2026 for autoimmune and inflammatory disease), PHICS (Phosphorylation-Inducing Chimeric Small molecules, partnered with Novo Nordisk since December 2024 for cardiometabolic disease), and tPRIME for restoring protective proteins such as p53 Y220C in oncology. Founded in 2022 out of Amit Choudhary's lab at the Broad Institute and Brigham and Women's Hospital with a $75M Series A led by MPM Capital and Longwood Fund. Photys operates no developer program and publishes no OpenAPI, GraphQL, AsyncAPI, WSDL or gRPC contract; its only machine-readable, agent-facing surface is the platform-provided Wix Site MCP endpoint served from its own host at www.photys.com/_api/mcp, which answers anonymously with nine tools over site content and business details.

Photys Therapeutics is listed with 1 API on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Drug Discovery, and Life Sciences.

Photys Therapeutics’ developer surface includes authentication and 9 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

10 more unmet checks in the Agent Readiness table above.

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

Access Clarity scores 0.0 — up to +20.0 composite points
Developer Ergonomics scores 11.9 — up to +17.6 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/photys-therapeutics/apis.yml: open an issue on github.com/api-evangelist/photys-therapeutics to ask a question or point us at an artifact you publish.
