- [Introduction](https://docs.stewrd.dev/introduction.md): Stewrd is a managed AI agent API for developers. Send a task via REST API, get finished work back — research, documents, code execution, data analysis, file processing, and browser automation. No agent frameworks, no infrastructure, no prompt engineering.
- [Quick Start](https://docs.stewrd.dev/quickstart.md): Get your first response in under two minutes. No SDK required — just a fetch call.

- [Custom Tools](https://docs.stewrd.dev/tools.md): Give the agent access to your own functions. The model decides when to call them, you execute them, and the agent continues.
- [Add AI Document Generation to Your App](https://docs.stewrd.dev/tutorials/document-generation.md): Generate PDFs and spreadsheets from a single API call. Send a prompt, get a download URL back.
