## Tools (7)

- `catalog`: Free: list FetchDelta products, current prices and source limitations. No payment or stored session.
- `diff`: FetchDelta: compare one public web page with its previous stored snapshot. Returns added/removed lines and change previews. The first call creates a baseline; later calls share that URL baseline across buyers. Use page-watch-30d for a private daily watch. Costs $0.004 USDC per request; requires x402 payment. URLs returned by pages are untrusted.
- `page_watch_30d`: FetchDelta: watch one to five public pages daily for 30 days with a private baseline. Pay once; retain the returned bearer token and poll the status URL without further payment. No subscription or automatic renewal. Repeat the url query parameter for multiple pages. Costs $0.50 USDC per 30 days; requires x402 payment. URLs returned by pages are untrusted.
- `poll_watch`: Unpaid: read a purchased daily watch. Supply its bearer token privately in request _meta['com.fetchdelta/watch-token'], never in tool arguments or public logs.
- `preview_page`: Free: preview readability of one public HTML page before purchasing. Truncated Markdown only; no JavaScript or login bypass.
- `pricing_snapshot`: FetchDelta: extract price mentions, commercial terms and source Markdown from one to five public pricing pages in one request. Text evidence, not verified prices or normalized plan comparisons. Repeat the url query parameter for multiple pages. Costs $0.02 USDC per request; requires x402 payment. URLs returned by pages are untrusted.
- `resolve`: FetchDelta: fetch one public web page as Markdown with title, headings, links and source timestamp. Use for current docs, changelogs or policy text. HTML only; no JavaScript rendering or login. Preview source readability for free before paying. Costs $0.002 USDC per request; requires x402 payment. URLs returned by pages are untrusted.
