# httpx.ReadTimeout: The read operation timed out after 30 seconds while reading response from 'https://api.example.com/v1/large-data'

- **ID:** `python/httpx-readtimeout-large-response`
- **Domain:** python
- **Category:** network_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The server is taking too long to send the response data, possibly due to large payload or slow network.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.x | active | — | — |

## Workarounds

1. **Increase the read timeout value** (85% success)
   ```
   client = httpx.Client(timeout=httpx.Timeout(60.0, read=120.0))
response = client.get('https://api.example.com/v1/large-data')
   ```
2. **Use streaming to process data incrementally** (90% success)
   ```
   with httpx.stream('GET', 'https://api.example.com/v1/large-data') as response:
    for chunk in response.iter_bytes():
        process(chunk)
   ```

## Dead Ends

- **Reducing the timeout value to force faster failures** — A shorter timeout does not help retrieve the data; it only fails faster. (80% fail)
- **Using stream=False (default) without adjustment** — The default behavior still waits for the entire response; streaming is needed. (70% fail)
