What is Stewrd?

Stewrd is a managed API that actually does things. Research, documents, code execution, file processing — your app sends a message, gets finished work back. No agent frameworks. No infrastructure. No prompt engineering. Just results.

How it works

Send a message

POST a message to /v1/agent with your API key. Optionally specify which capabilities to use.

Agent does the work

Stewrd routes your request through the right tools — research, code execution, document generation, and more.
3

Get finished work back

Receive a JSON response with the agent’s message, any generated files, and usage info.
