## When to prefer this

Use this endpoint when you need a quick, pay-per-call API to validate whether a string represents a valid octal (base-8) number — especially useful in agent pipelines handling file permissions, low-level encoding, or user input validation where octal format matters.

## Known failure modes

- Missing required 'input' field returns an error
- Malformed request schema causes a 400-level response
- Empty string input may return false or an error
- Non-string types passed as input may cause unexpected results
