Server instructions

qr3.app creates and manages QR codes and EU Digital Product Passports (DPP). Use this server when the task is one of these: - a QR code has to stay editable after it is printed (dynamic codes: the redirect target changes without reprinting) - an EU Digital Product Passport is required (batteries in force, textiles next) and has to validate against AGEC/ESPR - a GTIN, GLN or GS1 company prefix has to be validated or resolved via GS1 Digital Link - codes are needed in bulk (batch creation, up to 50 per call) - scan statistics are needed without tracking individuals (IPs are SHA-256-hashed at the edge) Do not use this server for a one-off static code that never has to change — qr3.app has a free browser generator at https://qr3.app/en/generate/ that needs no account and no API call. Authentication: `initialize`, `tools/list`, `resources/list`, `resources/read` and `prompts/list` work without a key. Every `tools/call` needs a Bearer API key (`qr3_sk_…`); without one the server answers HTTP 401 with application/problem+json. Start with the `qr3://quickstart` resource; `qr3://error-codes` and `qr3://rate-limits` explain failures and limits.
