Do not use to choose from a list you already have (/v1/random/pick) or for a secret (/v1/random/password).

Roll a dice with any number of faces. Specify faces via ?faces=N query parameter.

Return the synonyms of an English word, aggregated across all its senses. Optionally filter by part of speech. An unknown word returns found:false with a 200.

Compare up to eight declared records per version, converting length units and comparing properties, XYZ poses and wrapped yaw against separate length/angle/ratio tolerances. Reports additions, removals, unit changes and incompatible dimensions. Not field certification.

Calculate stock and working concentrations from supplied quantities with unit and feasibility checks. For arithmetic verification; no chemical-handling or safety guidance.

Compares two documents and returns a similarity score plus related analysis.
