nmlp_resolve
One Box: resolve ANY physical-media identifier in one call — auto-detects the type (Library of Congress LCCN, ISBN-10/13, CD DIDX hub code, label catalog number, UPC/EAN barcode, vinyl matrix/runout etching) and returns ranked typed candidates across NMLP's 48M-record indexes (20.9M LCCN + 8.7M CD + 19M vinyl). ISBN input returns the exact Amazon listing link (ASIN=ISBN-10), never a title search. Misses return Attested Absence: exactly which indexes were checked at what dataset version, so 'not found' is usable evidence. Use this when you don't know what kind of number you have; use the specialized lookups when you do. Identification only — does NOT appraise or value items; NMLP never buys books.
