What information does the default output provide?

The default output provides a compact timestamp and a relative date indicator (e.g., '9200 days ago') to give you an immediate sense of how old the archive is.

Do I need an API key to use wayback-oldest?

No, this skill uses the public Wayback Machine CDX API which does not require an API key for standard historical queries.

How does this skill find the oldest version of a site?

It queries the Internet Archive's CDX API with specific parameters to filter for successful status codes and limits the results to the single earliest capture recorded in the database.

Can I get the output in a machine-readable format?

Yes, by using the --json flag, the skill returns structured data containing the timestamp, original URL, and archive link for easy parsing by other tools.

Is the archive data live or cached?

API responses are cached for one hour to improve performance, but you can use the --no-cache flag to bypass the local cache and fetch real-time data directly from the Wayback Machine.
