Example prompt: Can you get me word autocomplete suggestions for the prefix 'inter'? I want to show typeahead options to my users as they type.

## When to prefer this

Use this endpoint when you need fast, lightweight word autocomplete or typeahead suggestions based on a text prefix. It is ideal for powering search boxes, text editors, or spelling assistants that need real-time word completion. Prefer this over a full dictionary lookup when you only have a partial word and need ranked completions.

## Known failure modes

- Missing or empty q parameter returns empty results or error
- Very unusual prefix with no matches returns empty array
- Network timeout or upstream Datamuse API unavailability
- Invalid query encoding for special characters

## How this service works

## Output
