X-PAYMENT: <signed-transferWithAuthorization>
{ ... }↳ first call →
402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.DESCRIPTION
Stateful webpage change monitor / page-watch with memory / URL change detector / TOS-policy diff / price-page tracker / status-page watcher / content monitor / persistent webpage diff. Caller picks a watch_id; server stores the page's hash + text in KV. On each subsequent call returns a changed flag, added/removed lines, and an LLM-summarized diff (Morpheus mistral-31-24b). Unlike webpage-diff (caller must remember prior hash), this endpoint owns the state. KV TTL: 365 days.
