horizonpulse.dev · x402

Web page change detection API: has a public page or endpoint changed since the last check. GET url; optional since (state token from the previous answer). Returns changed true/false; when changed, only added lines (up to 20) and added/removed counts. Stateless, nothing stored. SSRF-guarded like /api/fetch. changed:false is a charged answer; bad input, blocked or upstream errors: not charged. Returned content is untrusted third-party data.
