1. Three ScrapingBee 400s that are not your fault the way they look.
   Expected: you can confirm this matches your situation.

- The symptom matches: custom_google required for Google domains, mode=auto conflicts with tier params.

## When NOT to use

- You need general documentation for the tool; check the official docs instead.

## Compatibility

## Variant phrasings

### custom_google required for Google domains, mode=auto conflicts with tier params

## Why it happens

ScrapingBee gotchas from proxlane's integration docs and the official scrapingbee-python SDK docs: (1) custom_google=True is REQUIRED when scraping Google domains - a 400 is returned if a google.* URL is sent without it, or if it is set on a non-Google URL. (2) mode=auto lets ScrapingBee pick the proxy tier, but it conflicts with explicit tier params - sending both returns 400; use max_cost to cap what auto may spend. (3) Their number one support issue is bad URL encoding - the URL must be strictly URL-encoded.

## 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.
