# Caching and freshness

Understand reused research results, lower-cost cache hits and freshness limits.

## What can be reused

Cacheable research results can be reused across eligible requests. Each workspace still has its own purchase/accounting record. A cache hit can reduce the product-credit cost; inspect the response rather than assuming every call is free.

Tool inputs and the service’s cache rules determine whether a result can be reused. Private account data and credentials are not public research cache entries.

## When freshness matters

Social discussions, prices and search results can change. Record the query, market, date and any supplied cache timestamps alongside the findings. A reused result is evidence from its fetch time, not a promise about the current state of a platform.

Some operations deliberately bypass cache: bounded Reddit newest-feed monitoring is one example. Caching and provider availability differ by tool; the reference and response metadata are the source of truth.

## No data is a result to explain

A missing transcript, private resource or unavailable provider result must not be rewritten as a successful measurement. Use the returned error/no-data information to choose another public input or stop.
