Perplexity releases

Decisions API: URL fetching and page freshness Pass a page URL as state with mode: "web_grounding" to fetch its text before searching. The fetched text replaces the URL before search. The response returns the page in fetched_results and search evidence in search_results . Set max_staleness to the maximum page age in seconds since its last crawl.

Analytics API: credit-usage response update For dataset=credit_usage , responses from /v1/analytics/computer/usage and /v2/analytics/computer/usage currently omit the Credit Source breakdown. Total credit usage and the Model breakdown remain available. If your integration expects a fixed set of breakdowns, update it to read the returned categories list.

Perplexity updated effort levels in the Agent API, increasing maximum token limits, expanding search step maximums, and updating backend models.
