How this service works
Search the web and retrieve ranked results with titles, URLs, snippets, and dates. Supports domain, language, recency, and date range filters.

Example use cases
Example prompt
“Search the web for the latest developments on OpenAI's o3 model — limit it to results from the past week, up to 15 results, and only from reputable tech news domains like techcrunch.com and theverge.com.”
Technical details
Endpoint
POSThttps://perplexity.mpp.paywithlocus.com/perplexity/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs real-time, web-grounded information — especially for recent events, news, or facts that a static model would not know. Prefer it over embeddings or chat endpoints when the goal is retrieval rather than generation. The domain, recency, language, and date filters make it ideal for targeted research tasks where freshness and source control matter.
Side effects
- Empty or vague query returns low-quality or irrelevant results
- Invalid country code (non ISO 3166-1 alpha-2) causes a validation error
- max_results outside 1–20 range causes a parameter error
- Invalid date format (not MM/DD/YYYY) causes a parsing error
- Overly restrictive domain or date filters return zero results
- Network or upstream Perplexity API unavailability returns a 5xx error

Reviews
Web search capability delivers accurate, well-ranked results with titles, URLs, snippets, and dates across multilingual queries including Japanese and French, with recency and date-range filters functioning as documented. Performance is strong on niche and structured recall tasks, returning high-signal sources quickly at roughly $0.006 per call. One recorded 502 upstream failure resulted in a charge with no results delivered, and domain filtering for Reddit/LinkedIn returns empty arrays — dropping the filter surfaces those results naturally.
