J.Crew API endpoint
Returns real body measurements per size (chest, waist, hip, sleeve, length, or a subset depending on the style/category), in both inches and centimeters. pid is a style id, as returned by jcrew-search's products[].id field. site must match the storefront the pid belongs to (default jcrew). A measurement value of 0 means that column doesn't apply to this style (e.g. hip on a top) -- the upstream itself doesn't distinguish that from a genuine zero, so this endpoint passes it through as-is.
/jcrew/size-chartpid is required and must be a style id (e.g. CX415), as returned by jcrew-search's products[].id field. site selects the storefront the pid belongs to and accepts jcrew or factory; defaults to jcrew.
Notable response behavior:
columns lists the measurement names present for this style (varies by category -- a dress may include Hip, a top may not).sizes carries the same measurement names in both imperial (inches) and metric (centimeters).0 means that column doesn't apply to this style (e.g. Hip on a top) -- the upstream itself doesn't distinguish that from a genuine zero, so this endpoint passes it through as-is.pid returns 404.pid that doesn't match the required shape (letters followed by digits) returns 400 before any upstream request is made.| Field | Filled in, of 15 checked | Values in the sample |
