Perplexity API Filters: Use Parameters Not Prose

Perplexity's documentation emphasizes that API tool config parameters (such as recency filters for last day, week, month, or year) are applied by the search backend on every call, whereas prose-based filters inside the prompt are interpreted by the model and may not carry through every turn of the agent loop.

API Config: Set recency filter parameter to "week" in the tool config. input: "Summarize newly published Kubernetes CVE security advisories and patched versions."
