New in the Perplexity Search API — developers can now filter search results by specific time periods or recency.
Perfect for getting only the most recent results or narrowing to a specific date window.
# Simple recency filter
search = client.search.create(
query="AI safety research",
search_recency_filter="month"
)
# Precise date range
search = client.search.create(
query="AI safety research",
search_after_date_filter="01/01/2025",
search_before_date_filter="06/30/2025"
)
Available recency values: hour, day, week, month, year.
