Language & understanding
Summarize, translate, extract information, and work with text or attachments.
APIs & publishing for AI agents
Ship the app.
Borrow the superpowers
Give your AI agent practical APIs for language, web research, images, voice, and documents. Then publish its static browser app to a shareable URL with one request. Promptbox does not run app backends.
Static frontends only · Standard HTTP · No SDK required · Free publishing within shared limits
01 · Enhance
Add the capabilities
your app needs.
Choose a helper, read its request and response format, and connect it to your app. The reference includes working examples, limits, and error handling.
Web & research
Bring current web information and source-page content into your app.
Images & creative media
Generate images, edit visual inputs, and create music for a project.
Voice & audio
Turn recordings into text and give your app a spoken response.
Documents & files
Create PDFs, edit presentations, and process media with HTTP helpers.
Memory & delivery
Add notes and structured memory, then send results by email.

2. Build & testConnect the API and check the result.
3. Publish & shareUpload your app, verify its URL, and save its token.
02 · Publish
Give your app a public URL.
Publish a static browser app to apps.promptbox.cn or a document/media file to www.promptbox.cn/publish/. Promptbox cannot run PHP, Node.js, databases, private server code, or other app backends. Both expire after 30 days; updating an app restarts its clock. For hosting beyond 30 days, contact Promptbox at admin@promptbox.cn to discuss extended hosting services.
Publish Web Apps
AI agents: start with the site guide.
Send a directory name and HTML or ZIP with assets. Apps allow 25 MiB uploaded and expanded, with index.html at the ZIP root or inside one enclosing folder.
- Use
mode=app,directory, andfileor HTMLtext. - Save the returned URL and keep the UUID token private. Duplicate directories receive a numeric suffix.
- Send the token with a complete replacement build; omitted files are deleted and the 30-day lifetime refreshes.
curl https://www.promptbox.cn/api/publish.php \
-H 'Content-Type: application/json' \
--data '{"mode":"app","directory":"hello","text":"<!doctype html><title>Hello</title><h1>Hello world</h1>"}'For future updates, upload the full build. An HTML-only update removes all previously uploaded assets.
For HTML or ZIP files: -F 'mode=app' -F 'directory=my-app' -F 'file=@app.zip'. Apps share browser storage on apps.promptbox.cn, isolated from other Promptbox origins. Read storage and cookie details.
Files and Media
Publish a document, image, audio or video
Upload one file up to 10 MiB. PDF, DOCX, XLSX, PPTX and OpenDocument formats are supported, alongside common media. UTF-8 text files allow 1 MiB.
- Send
mode=fileand one multipartfile; an optionalnamesets its basename. - Keep the URL returned by the 201 response. Duplicate filenames get a numeric suffix.
- Files expire after 30 days. Documents download as attachments; macros and embedded active objects are rejected.
curl https://www.promptbox.cn/api/publish.php \ -F 'mode=file' \ -F 'name=project-report' \ -F 'file=@report.pdf'
Formats, limits and examples. Keep a local copy. Tokens apply to app updates only; document uploads always create a new file.
