■ Challenge detected

Searches the official EU open data portal and returns datasets with what decides whether they are usable: the licence, classified by whether commercial reuse is allowed and what attribution or share-alike it demands. A dataset under a non-commercial licence is marked as unusable for a paid product rather than listd as if equivalent. Each result also carries its publisher, country, last modification date, the distribution formats available and how many there are, and direct links.

POST/controversy-pulse$0.006Tracks how much is written about an organisation and in what tone, comparing a recent window against the same term own longer baseline, and returns both the volume ratio and the tone shift with the articles behind them. The framing is fixed and repeated in the response: this is an attention signal and not a judgement. A tone drop means more negative language is being used, not that something happened, and a product recall, a lawsuit and a critical opinion piece produce the same deflection.
POST/dataset-discovery$0.005Searches the official EU open data portal and returns datasets with what decides whether they are usable: the licence, classified by whether commercial reuse is allowed and what attribution or share-alike it demands. A dataset under a non-commercial licence is marked as unusable for a paid product rather than listd as if equivalent. Each result also carries its publisher, country, last modification date, the distribution formats available and how many there are, and direct links.
POST/supply-chain-pulse$0.007For each node you name — a port, a plant, a corridor, a supplier — the service counts reporting on five disruption themes over a recent window and compares it against the same term own longer baseline. Self-referential comparison is the design: Rotterdam and a regional port have entirely different normal reporting levels, so a fixed threshold is blind for one and a permanent alarm for the other, and only the ratio against a term own history means anything.
POST/paper-search$0.005Searches OpenAlex and Crossref for publications and returns each with its DOI, authors and their affiliations, publication year, venue, abstract, citation count and, where one exists, a direct link to a legally free full text with the licence it is offered under. OpenAlex stores abstracts as an inverted word index rather than text; it is reconstructed here, because the raw structure is unusable. Results can be filtered by year and restricted to open access.
