writer-sdk
The official Python library for the writer API
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has low install friction, carries a permissive Apache-2.0 license, and has no known vulnerabilities. Install it if you are building a Python application that needs to call the Writer API; it handles authentication, streaming, pagination, and async/sync patterns out of the box. The only prerequisite is a valid Writer API key.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires WRITER_API_KEY environment variable or explicit api_key parameter; Python 3.9 or higher.
- Low install friction with a pure-wheel distribution.
- Active maintenance with a recent commit on 2026-07-17 and releases within the past 73 days.

What it is and what it does
Writer-sdk is the official Python client for the Writer REST API, generated by Stainless. It provides both synchronous and asynchronous interfaces to call Writer's chat completion endpoints, with built-in support for streaming responses via Server-Side Events, automatic pagination, and file uploads. The library handles authentication via the WRITER_API_KEY environment variable and uses httpx for HTTP transport by default, with an optional aiohttp backend for improved async concurrency.
The package is designed for developers integrating Writer's AI capabilities into Python applications. It includes type hints throughout, supports Python 3.9 through 3.14, and abstracts away REST details so you can focus on building features. Streaming helpers and auto-paginating iterators reduce boilerplate for common patterns like iterating through paginated lists or processing streamed chat deltas.
Use it for
- Build a chatbot or conversational AI application that calls Writer's chat API with streaming responses.
- Integrate Writer's language models into a data pipeline or batch processing system using async calls.
- Fetch and iterate through paginated lists of resources without manual page management.
- Stream chat completions to a web UI or terminal, displaying tokens as they arrive.
- Prototype or test Writer API endpoints before deploying to production infrastructure.
