## TL;DR

Set content_encoding to base64 or the binary comes back mangled. Three Oxylabs params that bite silently.

## Fix

1. Set content_encoding to base64 or the binary comes back mangled.
   Expected: You get the expected result; the problem is gone.

## When to use

- You are setting up or using this Oxylabs feature.
- The symptom matches: base64 for image downloads, browser_instructions needs render html, tag jobs with client_notes.

## When NOT to use

- Unrelated Oxylabs issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Variant phrasings

### base64 for image downloads, browser_instructions needs render html, tag jobs with client_notes

## Why it happens

Oxylabs' official agent skill: three param-level gotchas. (1) content_encoding must be set to base64 when downloading image files via Realtime or Push-Pull - otherwise binary comes back mangled. (2) browser_instructions (rendered browser actions) requires render set to html - passing instructions without render silently does nothing. (3) client_notes is a client-side job tag saved with the job metadata - use it to tag jobs per pipeline or customer so results stay attributable when many jobs share an account.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
