GTIN barcode validator: validate and convert GS1 identifiers: GTIN-8, GTIN-12 (UPC-A), GTIN-13 (EAN-13), GTIN-14, GLN and SSCC. Returns the check-digit verdict, the computed correct check digit, the GTIN-14 form with its indicator digit, and conversion between GTIN-8, -12, -13 and -14. No company-prefix split is returned: GS1's prefix-length table is no longer public data. Also computes a missing check digit from a partial code. Structure only, no product database.

Offline validation of product barcode numbers: EAN-8, UPC-A, EAN-13 and GTIN-14, using the GS1 mod-10 weighted checksum. Catches corrupted GTINs in supplier catalogs before marketplace publication (Amazon/Google reject invalid GTINs). Query: ?gtin=4006381333931. Returns valid flag, detected format, GS1 member-org prefix and the computed check digit. Deterministic, cached 1 year.

Identifies exercise equipment from images or input data.

Compress a string with gzip (RFC 1952) and return it as base64. Reports input bytes, output bytes, and the compression ratio so you can decide if it was worth doing. Input can be plain text (utf8) or already-binary content (base64 or hex).

Decompress a base64-encoded gzip payload. Returns the result as utf8 (text) or base64 (binary). Refuses to expand past 10MB to defend against zip bombs.

Prueft die IBAN nach ISO 13616 und ISO 7064 mit Pruefsumme mod 97-10 gegen die Laengentabelle von 74 Laendern, zerlegt die BBAN fuer elf Laender in Bankleitzahl und Kontonummer, meldet SEPA-Zugehoerigkeit und prueft eine mitgegebene BIC auf Format und Landesgleichheit. Trifft keine Aussage zu Existenz oder Deckung.

Normalizes whitespace, inserts a caller-supplied visible marker after every selected number of words and at the end of a final partial interval, then reports source and output digests. This deliberately visible text annotation is not a robust image, audio or cryptographic watermark and can be removed by editing.

Enumerates feasible player pairs, ranks them by rating gap then worst latency, and greedily selects disjoint pairs. This is a transparent local pairing heuristic, not globally optimal team balancing, skill inference, anti-smurfing, or a live queue service.

Takes two documents, by URL, inline base64 or raw text, extracts the text of each and compares them. Paragraphs are the unit: the answer lists every block that was removed, added, or kept but reworded, and for reworded blocks it names the individual words that went and came, so a single changed number in a long clause is visible instead of the whole clause being flagged. Alongside the content diff a structural comparison reports headings, paragraph, list and table-line counts on both sides.

Finds the external contours in a caller-supplied binary mask and reports, for each, its area, perimeter, centroid and bounding rectangle, plus the total foreground pixel count. The division of labour is deliberate: segmentation is a domain decision, so the mask comes from you and the measurement comes from here, which keeps the numbers reproducible and independent of any threshold this service might have chosen.

Broker-Zeit und UTC umrechnen. IANA-Zeitzone zwingend; doppelte Ortszeit nur mit ausdrücklich geliefertem fold, nicht existierende Zeit wird abgewiesen. Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.

Loads a package list into one loading space and returns the plan, not an estimate. The floor starts as one free surface; packages are sorted by footprint, then height, then weight, then identifier, and each one is placed on the lowest, then frontmost, then smallest free surface it fits on, turned by 90 degrees around the vertical axis where that makes it fit.
