# Synyi (森亿智能 / Shanghai Synyi Medical Technology) > Synyi is a Shanghai-based medical artificial-intelligence company founded in April 2016 that > builds AI and big-data systems for hospitals. Its platform standardizes and mines the > unstructured clinical records held in Chinese hospital information systems using medical NLP, > knowledge graphs and multi-agent LLM applications, and sells that capability as deployed > hospital software across clinical decision support, medical-record quality control, hospital > operations management and clinical research. IDC's "China Healthcare Big Data Solution Market > Share, 2023" ranked Synyi first in its market. IMPORTANT FOR AGENTS AND INTEGRATORS: Synyi publishes NO public API, NO developer portal, NO API documentation and NO machine-readable contract. As of 2026-08-29 there is no OpenAPI, GraphQL, AsyncAPI, gRPC or WSDL contract on any Synyi host, no MCP server, and no A2A agent card. Synyi's products are enterprise systems deployed inside customer hospitals and reached through a sales conversation, not through a self-serve API. Do not attempt to construct requests against a Synyi API — none is published. See "Contract discovery" below for the exact probes and their HTTP statuses. ## Company - Legal entity: 上海森亿医疗科技股份有限公司 (Shanghai Synyi Medical Technology Co., Ltd.) - Founded: April 2016, Zhangjiang Hi-Tech Park, Shanghai - Headquarters: Pudong New Area, Shanghai, China - Regional centers: Zhongshan, Guangdong (southern center); Changchun, Jilin (northern center) - ICP filing: 沪ICP备16018846号-1 · Public security filing: 沪公网安备 31011502004671号 - Website: https://www.synyi.com/ - Company profile: https://www.synyi.com/about/company - Contact: https://www.synyi.com/about/contact - News: https://www.synyi.com/media/news - Customer showcase: https://www.synyi.com/customer/showcase - GitHub organization: https://github.com/synyi ## Products and solutions - AI 诊所 (AI Clinic) — https://www.synyi.com/solution?id=43 End-to-end AI-driven care model: voice-based intake and history taking, AI-directed physical examination via connected devices (temperature, laryngoscope, heart/lung sounds), assisted diagnosis, risk alerting and guideline-conformant treatment recommendation, with a human-in-the-loop safety layer of clinical rules, pathways and multi-agent cross-validation. - 临床辅助决策与质控智能体 AI (Clinical decision support and quality-control agent AI) Monitors the full treatment and medical-record pipeline against hospital data, raising automated defect alerts and managing them to closure. - 医院运营管理智能体 AI (Hospital operations management agent AI) — https://www.synyi.com/solution?id=36 Conversational metric monitoring, automated root-cause analysis, 24x7 alerting with pushed intervention plans, and one-click operations reporting. - 临床科研智能体 AI (Clinical research agent AI) — https://www.synyi.com/solution?id=34 Natural-language cohort search, automated research-grade data cleaning, built-in analysis prompts, patient recruitment and enrollment, and automated form filling. - 新一代医生工作站 (Next-generation clinician workstation), 临床质量管理 (clinical quality management), 指挥调度中心 (command and dispatch center), 绩效与效能管理 (performance management), 精益运营决策分析 (lean operations analytics), 区域数据及资源协同 (regional data and resource coordination). ## Core technology - https://www.synyi.com/core-tech - Frontier AI algorithms: multi-domain AI agent center, disease-risk prediction model suite, multimodal model library, AutoML engine, high-performance medical NLP. - Medical knowledge engineering: large-scale medical knowledge graph, medical variable center, all-disease medical rule center, high-quality medical AI training corpora, 100+ standardized disease-specific datasets. - Heterogeneous data governance: normalization of medical terminology across all domains, multimodal data-quality monitoring, data-lineage framework, full-element data asset center, high-concurrency real-time medical data governance engine. - The team reports 70+ published SCI papers. ## Certifications published by Synyi - ISO/IEC 27001 and ISO 9001 (listed by name on https://www.synyi.com/about/company; no certificate number, issuing body or expiry is published) - 国家级专精特新“小巨人”企业 (MIIT national "Little Giant" enterprise) - 高新技术企业 (National High-Tech Enterprise, awarded November 2018) - 上海市企业技术中心 (Shanghai Municipal Enterprise Technology Center) ## Open source Synyi's AI team publishes open-source developer tooling — not API client SDKs, because there is no API to wrap. All of it is dormant; the most recent first-party release was 2022-11-21. - poplar / poplar-annotation — web-based NLP annotation tool (TypeScript, GPL-3.0, 528 stars) https://github.com/synyi/poplar · https://www.npmjs.com/package/poplar-annotation (2.0.3, 2020-02-27) - synyi-annotation-tool — SVG library for medical-history annotation (Apache-2.0) https://www.npmjs.com/package/synyi-annotation-tool (0.5.1, 2018-06-13) - synyi-faas — client for Synyi's internal FaaS runtime https://www.npmjs.com/package/synyi-faas (0.3.9, 2022-11-21) · https://github.com/synyi/faas.js · https://github.com/synyi/faas.go - Also in the org: xpath, gopy, annotation-viewer, kityminder-editor, crf.js ## Contract discovery — what was probed and what it returned (2026-08-29) - https://www.synyi.com/openapi.json, /swagger.json, /api-docs, /docs, /api, /developer, /llms.txt, /sitemap.xml — every one returns HTTP 302 to the site root. The host serves a blanket catch-all redirect; a control probe of /nonexistent-abc123 returns the identical 302. - https://api.synyi.com/ and /openapi.json, /swagger.json, /v1/openapi.json, /api-docs, /v2/api-docs, /docs, /mcp — HTTP 503 (nginx vhost with no upstream). - https://open.synyi.com/ — HTTP 200 serving the stock "Welcome to nginx!" default page; /openapi.json, /swagger.json and /docs return 404. Same for developer., docs., openapi. (all subdomains resolve through a wildcard record to the same two AWS China addresses). - https://www.synyi.com/.well-known/{security.txt, openid-configuration, oauth-authorization-server, oauth-protected-resource, api-catalog, ai-plugin.json, agent-card.json, agent.json} — all HTTP 302 to the site root. No document is served. - No GraphQL endpoint, no MCP server, no A2A agent card was found on any host. - https://www.synyi.com/en — HTTP 302 to the site root. Search engines still index English pages such as /en/product-categories/13.html, but the English site has been withdrawn and every one of those URLs now redirects to the Chinese homepage. ## Commercial model No public pricing, no plan tiers, no self-serve signup and no free tier. Every product page's call to action is 方案咨询 (request a solution consultation). Integration and deployment happen through Synyi's sales and delivery organization. ## Provenance Generated by the API Evangelist enrichment pipeline on 2026-08-29 from Synyi's own public site, the npm registry, the GitHub API, and direct HTTP probes recorded above. No API surface was found and none was invented.
