Several carriers can match the same pattern; each candidate says whether its check digit passed. It does not read live scan events (carriers serve them only th

Look up a product barcode number: identify and validate EAN-13, EAN-8, UPC-A, UPC-E, GTIN-14, ISBN-13/10, ISSN and ISMN codes (wrong check digits are reported with the correct digit), convert between forms (GTIN-14, EAN-13, UPC-A, ISBN-10 <-> 13) and decode the GS1 prefix. Then fetch product data from open databases: name, brand, quantity, categories, image, labels, Nutri-Score (food, cosmetics, p

Evaluates caller-supplied telemetry samples against declared reaction-time, actions-per-second, movement-speed, and impossible-event rules. Flags are review signals only; the service does not identify software, inspect a device, establish intent, or justify an automatic ban.

Normalizes caller-supplied blink deviation, lip-sync error, spectral discontinuity, compression inconsistency and metadata anomaly using declared fixed weights. It does not inspect media, establish authenticity, identify a generator or replace human forensic review; the result is only as reliable as the supplied signals.

Curated reading list on QE for tutoring agents, quiz generators, and reading apps — 168 public-domain books (e.g. A Study of Recent Earthquakes, The chemistry, properties and tests of precious stones, Field book of common rocks and minerals : $b for identifying the rocks and minerals of the United States and interpreting their origins and meanings). Full-text retrieval with drill-down routes for c

Address Poisoning Detector analyses only the evidence supplied by the caller. It does not claim to query a chain, identify a legal status or replace an independent audit. Missing signals lower confidence and are listed explicitly; every classification includes the exact thresholds used.

Use when an agent needs fresh identifiers — UUID v4/v7, ULID, nanoid, secure passwords, or memorable passphrases. Cryptographically random via WebCrypto, generated locally, no upstream. Pass type and count (1-100). Use permitted: build it into your products and services, paid or free. Raw redistribution of the feed itself is prohibited.

Sorts caller-supplied non-negative balances and computes the standard finite-sample Gini coefficient plus top-one and top-ten-percent shares. Results cover only supplied accounts and do not identify common ownership, custodians, vesting, delegation, or off-chain claims.

Finds up to 100 faces in a JPEG or PNG at a URL with Amazon Rekognition and describes each: position, estimated age range, emotions, smile, glasses, beard, eyes and mouth open, pose and image quality. It does not identify anyone or compare faces.
