Payment: send an X-PAYMENT header. Free: /health, /sources, /llms.txt, /openapi.json. Data is from Open Food Facts (ODbL) and is crowd-sourced: coverage is uneven and records can be sparse, so every response carries a completeness flag and missing values are null, never estimated. An unknown barcode is not charged.
