Technical details
Endpoint
GEThttps://agent402.tools/api/search-suggestWhen to prefer
Use this endpoint when you need lightweight, fast query suggestion or autocomplete functionality without spinning up a full search engine. Ideal for query expansion pipelines, building search UIs, did-you-mean features, or exploring related topics from a seed term. Prefer this over a full-text search endpoint when you only need suggestion strings, not actual search results or ranked documents.
Side effects
- Missing required 'q' parameter returns an error
- Query exceeding 400 characters is rejected
- Count parameter outside 1-20 range may return default of 5 suggestions
- Empty or whitespace-only query may return empty array
- Network or service unavailability returns HTTP error
