Accro Bioscience (Suzhou) Limited, trading as Accropeutics, is a clinical-stage biopharmaceutical company founded in 2017 with operations in Suzhou, China and New York. It develops small-molecule therapeutics against regulated cell death — necroptosis, pyroptosis and ferroptosis — targeting the cell-death-to-inflammation loop behind inflammatory, fibrotic, autoimmune and oncology disease. Its pipeline is led by AC-101, an oral selective RIPK2 inhibitor in Phase Ib for ulcerative colitis with FDA clearance for a Phase II multi-regional IBD study; AC-201, a TYK2/JAK1 pseudokinase inhibitor licensed to Fosun Pharma for Greater China as FXS5626; and AC-003, a RIPK1 inhibitor in Phase Ib for acute graft-versus-host disease with FDA Orphan Drug Designation. It closed a $50M Series C led by OrbiMed in May 2026. Accro Bioscience sells drug candidates, not software: it runs no developer program and publishes no API, SDK or machine-readable API contract.
Accro Bioscience is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Drug Discovery, and Clinical Trials.
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 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

detail: Accro Bioscience (Suzhou) Limited is a clinical-stage biopharmaceutical company whose product is a small-molecule
drug pipeline (AC-101, AC-201, AC-003), not software; its entire public surface is the accropeutics.com corporate site
— about, focus areas, pipeline, partnerships, news, join us, contact — with no developer, docs, portal or integration
link anywhere in the nav or footer, and the site does not even serve a /robots.txt or /sitemap.xml. Every REST/GraphQL/agent-card,
/llms.txt and /.well-known/ path probed on both www.accropeutics.com and accropeutics.com returns an identical 548-byte
hard 404, verified against a random control path returning the same body and byte count; api., dev., docs., developer.,
portal., data. and mcp..accropeutics.com do not resolve in DNS, and there is no GitHub organization and no npm or PyPI
package under either the Accro Bioscience or Accropeutics name.
