Introducing Exa Snapshot, A New Way to Search the Past
Blog post from Exa
Exa has introduced Snapshot, a research-preview capability that provides a versioned view of the web through more than 400 billion webpage snapshots collected over two decades. Available through the Search and Contents APIs via the `snapshotAsOf` parameter, it returns search results and webpage content as they existed on a specified date. The feature is intended to support reproducible AI evaluations by preventing agents from finding solutions that appeared online after a task was created, helping distinguish genuine problem solving from copied answers. Snapshot also supports financial and quantitative research by enabling point-in-time web-data backtesting without requiring extensive historical data collection. Users can access it through Exa’s dashboard or APIs, while enterprise details such as full index coverage, rate limits, and zero-data retention are available through Exa’s team.
