list_feeds

List every change-intelligence feed: source slug, label, the question each answers, per-call prices, paid x402 endpoints, and free discovery URLs. There are ~120 feeds, so pass `category` to filter (e.g. 'security', 'regulatory', 'packages', 'premium', 'infrastructure', 'compliance') and/or `compact: true` to keep the payload small. Use the returned `source` slug with preview_feed.

read-only

Argument	Type	Description
compact	boolean	Return only source/label/question/price to keep the payload small
category	string	Filter to one category (see the `categories` list in the response)
