• interpret_commercial_changeA

  project-little-weirdoA

  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.

  402 DispatcherA

  FREE. Rank Bazaar APIs for a natural-language task without paying. Prefer over search_bazaar when you need ranked candidates (economy=cheapest; verified=reliability score). Prefer over list_discovered_apis when matching a task, not dumping the cache. Use route_and_call next to execute; do not use this to pay.

• award_stateA

  find-missingA

  Given a real, awarded EU public-procurement notice (TED), resolve the winning company's real commercial-registry status TODAY (active, dissolved, insolvency, etc.) - answers "is the company that won this public contract still alive?". Args: notice_id: the TED publication-number of an AWARD notice (e.g. "15-2026") - must be a can-standard/can-social/can-desw/ can-defence notice with a chosen winner, not the original contract notice (cn-standard). api_key: optional - a free key obtained from POST https://api.nkodatalabs.com/v0/keys. Without one, this call still works within a free anonymous trial (5 calls/day per caller IP) - see the response's "trial" field. Coverage today (published honestly, not hidden): Spain and France resolve live via each country's own commercial registry. UK and Hungary are not resolvable yet - UK needs a free Companies House API key not yet configured on this service, Hungary has no free public registry API at all. Natural-person awardees are excluded, never resolved as a company.
