  "description": "Closed catalog of public SaaS and cloud pricing pages, grouped into two named sets (inference and devtools). Each listed vendor is fetched on a ~6 hour schedule in a real browser, extracted into one JSON shape (plan names, prices, currency, billing period, printed price text, features when present, snapshot time), and diffed for detected plan/price/billing-period changes. The paid unit is the set change feed, GET /api/sets/{set}/changes: 0.01 USDC on Base or Solana via x402 v2, charged only when a change was recorded after your since cursor, and free when the window is empty. Per-slug snapshot and changes calls remain 0.01 USDC each. Not a live scrape-any-URL service and not unpublished or negotiated rates. Discover sets and slugs free at GET /api/sets and GET /api/monitors. No API key. $0.01 USDC per paid call via x402 on Base or Solana.",
