Find open research datasets with a plain licence verdict per dataset: public domain, attribution, share-alike, no-derivatives, non-commercial. Find open datasets you are allowed to use. Pass ?q=electricity prices and get research datasets from Zenodo (700k+), each with a plain licence verdict read from the depositor's structured licence: public domain, attribution (credit needed), share-alike (derived data must carry the same licence), no-derivatives, non-commercial or not stated.

Public holidays for the Netherlands, Belgium and Germany (nationwide) for any year 1900-2200, computed from the statutory rules and the Easter date: date, English and local name, with notes where a day is commonly worked. Use it for scheduling, delivery dates, payment terms and staffing in the Benelux and Germany.

Validate an IBAN: country, expected length, ISO 13616 mod-97 check digits, and the bank code part for common countries (NL, BE, DE, FR, GB, ES, IT, AT, CH, LU), plus the electronic and printed formats. Use it before sending a payment or storing bank details. Pure computation: the IBAN is not stored or forwarded, and no account existence check is made.

Current local time, UTC offset and daylight-saving status for any IANA time zone (e.g. Europe/Amsterdam, America/New_York, Asia/Tokyo), plus the next DST transition within a year. Computed from the IANA time zone database. Use it for scheduling across time zones and for agents that need a trustworthy clock.
