SEMANTIC INTERPRETATION over PRICING AND COMMERCIAL-OFFER PAGES ONLY. Requires a target that already has two persisted observations with a deterministic CONTENT_CHANGED verdict; it never refetches the page and never decides whether a change occurred. Input: targetId (returned by observe_public_page), optionally fromObservationId/toObservationId. Returns classified commercial changes (price, plan, discount, availability, packaging...) where every claim quotes observed before/after text, plus rejected claims and their rejection reasons. Uncertainty: unsupported, immaterial, numerically inconsistent or low-confidence claims are discarded. Non-commercial pages return INSUFFICIENT_EVIDENCE with no changes. There is no guarantee that a page contains commercial intelligence. Cost: free beta, model-backed and separately rate limited per credential.
Target UUID from a previous observation.
Optional 'after' observation UUID.
Optional 'before' observation UUID.

}DETERMINISTIC OBSERVATION. Fetches one lawful public web page and records a bounded representation of it (title, normalized text length, content fingerprint). If the page was observed before, returns an arithmetic comparison against the previous observation: BASELINE_CREATED, NO_CHANGE or CONTENT_CHANGED. Makes no claim about meaning. Input: url (public http/https page). Private, loopback and internal addresses are refused; redirects, response size and timeouts are bounded. Uncertainty: the verdict is arithmetic, not semantic. A CONTENT_CHANGED verdict proves the content differs, not that the difference matters. Cost: free beta, rate limited per credential. No payment capability exists.
| Argument | Type | Description |
|---|---|---|
| url* | string | Absolute http(s) URL of a lawful, public, non-credentialed page. |
