## Installation

**NOTE**: This is beta software. Please be sure to pin your dependencies.

```bash
pip install httpx-sse=="0.4.*"
```

## Quickstart

`httpx-sse` provides the [`connect_sse`](#connect_sse) and [`aconnect_sse`](#aconnect_sse) helpers for connecting to an SSE endpoint. The resulting [`EventSource`](#eventsource) object exposes the [`.iter_sse()`](#iter_sse) and [`.aiter_sse()`](#aiter_sse) methods to iterate over the...

## AI interpretation — verify before relying

Provides synchronous and asynchronous helpers to consume Server-Sent Event (SSE) streams from HTTP endpoints using HTTPX, with built-in event parsing and reconnection support via Last-Event-ID.

Verdict: Lightweight, dependency-free SSE consumer for HTTPX with solid coverage of the SSE spec and both sync/async support. Beta status and 307 days since last release warrant pinning to 0.4.* as the maintainer recommends. No known vulnerabilities and permissive MIT license make it safe for most use cases.
