# Coohua (酷划在线) > Coohua — 北京酷划在线网络技术有限公司 — is a Beijing mobile advertising company founded in > March 2014 that built China's incentive- and lock-screen-advertising category. Its flagship > apps, Coohua Lockscreen (酷划锁屏) and Tao News / NewsEarn (淘新闻), paid users cash for > unlocking their screens and reading content, and monetized that attention for advertisers > across internet, finance, automotive and e-commerce verticals. Backed by Qiming Venture > Partners and SIG (US$20M Series B, May 2015). Coohua publishes **no public API, developer > portal, SDK, or machine-readable specification**. This file is generated by API Evangelist > from the company's own public pages and its GitHub organization; it is not published by > Coohua. ## Status of the developer surface - No OpenAPI, Swagger, GraphQL, AsyncAPI, MCP or A2A surface exists on any Coohua host. - Probed and missed: `/openapi.json`, `/openapi.yaml`, `/swagger.json`, `/v1/openapi.json`, `/api-docs`, `/docs`, `/redoc`, `/graphql`, `/llms.txt` and the full `/.well-known/` set — across `www.coohua.com`, `coohua.com`, `www.coohua.cn`, `api.coohua.cn`, `open.coohua.cn`, `developer.coohua.cn` and `docs.coohua.cn`. See `well-known/coohua-well-known.yml`. - The `coohua.cn` domain is dead: the apex has no A record, and every subdomain is a DNS wildcard to 39.106.94.60 answering openresty HTTP 500 on every path. - The `coohua.com` site root now serves an unrelated product page (海南耀游奇迹 / 猪猪世界, filed by 海南耀天网络技术有限公司 under 琼ICP备20000955号-2). The original Coohua corporate pages survive as individual files beneath that root and still carry Coohua's own 京ICP备14013745号 filing. - Advertising business is transacted by sales email (sale@coohua.com), not by API. ## Company pages - [About Coohua Lockscreen — 关于酷划锁屏](https://www.coohua.com/about.html): company overview, Beijing address, ICP filings. - [Advertising cooperation — 广告合作](https://www.coohua.com/partner.html): the ad-platform pitch and the sales contact that stands in for a developer program. - [FAQ — 常见问题](https://www.coohua.com/faq.html): end-user questions about earning and withdrawing cash rewards. - [Terms of service — 用户协议](https://www.coohua.com/terms.html): 酷划软件许可及服务协议. - [Contact — 联系我们](https://www.coohua.com/contact.html): address, phone, sale@coohua.com. - [User protection notice — 用户权益保护通告](https://www.coohua.com/safe.html). - [Careers — 加入我们](https://www.coohua.com/join.html): engineering roles, hr@coohua.com. - [Company profile — 公司简介](https://www.coohua.com/coohua_mobile/html/introduce.html): founding timeline and funding milestones. ## Code - [github.com/coohua-dev](https://github.com/coohua-dev): Coohua's GitHub organization, 8 public repositories. Holds CocoaPods private spec repos (`CHSpecs`, `Specs`) for the iOS modules behind the two apps, plus Android base/common/push/statistics libraries. All source URLs in the podspecs resolve to `gitlab.coohua.com`, which is not reachable publicly, so none of the pods are installable by a third party. ## API Evangelist artifacts in this repo - [packages/coohua-packages.yml](packages/coohua-packages.yml): the six first-party CocoaPods modules with versions and release dates (newest 2020-06-08). - [well-known/coohua-well-known.yml](well-known/coohua-well-known.yml): the full probe record, 41 paths across 7 hosts, zero documents found. - [security/coohua-domain-security.yml](security/coohua-domain-security.yml): TLS/HSTS/DNSSEC/ CAA/SPF/DMARC posture for coohua.com. - [plans/coohua-plans-pricing.yml](plans/coohua-plans-pricing.yml): plan_count 0. - [rate-limits/coohua-rate-limits.yml](rate-limits/coohua-rate-limits.yml): limit_count 0.
