Decode, generate or validate barcodes and QR codes

Decode, generate or validate barcodes and QR codes. Decode reads up to 32 codes from a public HTTPS image (QR, Data Matrix, Aztec, PDF417, EAN, UPC, Code 128 and more); generate answers a temporary HTTPS URL to a PNG or SVG, kept one hour; validate checks a payload and its check digit. POST /v1/barcode with operation. Pay per request in USDC; no account, no API key.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
