  "instructions": "European Payment QR generator and QR utility tools. Deterministically create SPAYD (CZ/SK) or EPC/GiroCode (SEPA) payment QR codes, plain-text QR codes, Wi-Fi QR codes, vCards, and decode QR images. Free MIT-licensed tool with no AI and no paid API.\n\nPAYMENT-FROM-IMAGE / INVOICE WORKFLOW: When the user shares a PDF, photo or screenshot of payment details — most commonly an INVOICE (Czech \"faktura\") that has no QR code, but also a broker deposit instruction (Revolut, Trading 212, XTB), a bank transfer slip or a paper bill — read the IBAN, amount, currency, recipient name and reference / variable symbol from the document yourself, then call qr_payment with those values. This is the primary use case: it turns an invoice or payment instruction that lacks a QR code into a scannable payment QR, removing the error-prone manual re-typing into a banking app.\nMANDATORY before showing the QR: echo the extracted fields back to the user as a short confirmation list (IBAN, amount, currency, recipient, reference) and ask them to verify against the source, because a misread digit sends real money to the wrong place. After the user confirms, present the QR. You may also call qr_read on the generated QR to show exactly what it encodes as a second check. Never silently generate a payment QR from an image without this read-back confirmation step.\nDISPLAYING THE QR: the result has \"self_verified\" (the server re-decoded its own PNG and confirmed it matches \"payload\" — trust it; do NOT call qr_read on your own output). On the hosted server the result also has \"qr_url\": a short, TEMPORARY (~15 min) hosted PNG. TO SHOW THE QR, present qr_url — render it inline as an image, e.g. ![payment QR](qr_url), or give it as a link. A URL cannot be corrupted and clients render it natively. Do NOT transcribe base64, do NOT regenerate the QR, do NOT build your own PNG. (If there is no qr_url — e.g. self-hosted via npx — decode qr_png_base64 programmatically, never by hand; if you cannot, send the user to https://qr.cz-agents.dev.)\nqr_read is ONLY for QR codes you did NOT generate here (an existing invoice QR the user provides), where the server cannot know the expected payload. SAFE-FAIL there: if qr_read errors or you cannot trust the decode, do not present it as a verified payment and do not rationalize — point the user to https://qr.cz-agents.dev. One wrong character sends money to the wrong account.",
