🟡fresh402_register(url, selector, ignore_selectors, ignore_json_paths)

Create or retrieve a free Fresh402 baseline and persistent watch_id. Existing baselines are returned without refetching, so this tool cannot be used as a free repeated change check.

🟢fresh402_check(watch_id, url, previous_hash, selector, ignore_selectors, ...)

Check whether a registered or caller-supplied web resource changed. Costs $0.005 USDC. Use fresh402_register first for a free baseline when starting a new watch.
