POST /api/skill/feed-watch

live

Bundled execution of the Feed watch workflow - Monitor an RSS/Atom feed in one call: parse the feed, read the top story in full, extract the keywords driving the cycle, and diff the item list against your last run to isolate what's new. One x402 payment runs 4 underlying tools (feed-parse, extract, keywords, text-diff); partial-success per step.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
