A search recency filter describes a retrieval constraint; it does not certify that every business fact in the generated answer is current. Check the source's timing and the fact's effective date separately.
Use two clocks
The retrieval clock describes the search window or collection time. The business clock describes when the fact became true, changed or expired.
Perplexity's current Agent API web search documentation defines relative recency windows for its search filter. That is a documented API control. It is not a guarantee that a retrieved page's statements remain accurate, and it does not establish that a different integration used that setting.
Review the fact, not just the page date
Illustrative example: a recently updated comparison page still repeats a retired subscription plan. The page is recent, but the plan claim is stale.
The reverse can also happen: an older technical specification may still be the current authoritative record. Excluding it solely because of age can remove useful evidence.
For each time-sensitive claim, record the source publication or update date if available, the observation time, the fact's effective period and the authoritative place where the business maintains it. Keep unknown dates explicitly unknown.
A practical freshness check
- Identify claims about price, availability, policy or current capability.
- Open the cited source and inspect the relevant passage.
- Follow its original or authoritative reference when possible.
- Compare the fact with the current official record.
- Record a supported-as-of date or mark the claim unresolved.
- Retain the actual retrieval configuration if it is available.
A date in a search result may describe a page event rather than the date of the underlying fact. Do not infer freshness from that date alone.
Design the comparison honestly
When testing recency settings, keep prompt text and provider configuration fixed except for the declared filter change. Record reduced coverage or different source mixes. A more recent set is not automatically a more accurate set.
This is an API research workflow, not a statement that MonitorMyGEO offers a configurable recency-filter control. Check actual product controls before describing one.
Read the brand recommendation guide for interpretation limits. Next, review provider measurement coverage and fact-check one time-sensitive answer before calling it current.
