## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability miniframe-pix-br-code-generator-2c572b00 -d '<json body>'
```

Example prompt: Generate a Pix BR Code and QR image so I can receive R$250 from a client — my Pix key is minha@empresa.com.br, merchant name is 'Loja Exemplo', city is 'São Paulo', and the description should say 'Pedido #1042'.

## When to prefer this

Use this endpoint when you need to programmatically generate a Pix payment code or QR for any Brazilian payment scenario — invoices, donations, bill splits, or e-commerce checkouts — and want a Central Bank spec-compliant BR Code and QR PNG without storing the Pix key. Prefer this over generic QR generators because it produces a fully valid Pix EMV payload usable in any Brazilian banking app.

## Known failure modes

- Invalid or malformed Pix key format — returns error if key does not match CPF/CNPJ/email/phone/random UUID patterns
- merchant_name or key missing — required fields; omitting either returns a 400-level error
- txid exceeds 25 characters — truncation or rejection depending on implementation
- merchant_city exceeds 15 characters — may be truncated or rejected
- Non-BRL amount or negative amount — may produce an invalid BR Code
- Payment processing error or x402 payment failure — call not executed if USDC micropayment fails

## How this service works

Use when someone needs to receive money in Brazil — an invoice, a split bill, a donation, a checkout. Builds a Pix BR Code ("Copia e Cola" string payable in any Brazilian bank app) plus a QR PNG, per the Central Bank spec; the key is not stored. JSON body: key and merchant_name required; amount, merchant_city, txid, description optional. Returns brcode and qr_png_base64.

## Output

Returns a JSON object containing: `brcode` (the Pix 'Copia e Cola' EMV string payable in any Brazilian bank app) and `qr_png_base64` (a base64-encoded PNG of the scannable QR code). The key is not stored server-side.
