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.

Example use cases

Charity fundraiser donation QR code

“I'm collecting donations for a local shelter and need a Pix QR code people can scan to contribute — set it up as an open-value donation so donors can give whatever they want, use my CPF key, put 'Abrigo dos Animais' as the merchant name, and mark it as 'Donation' in the description.”

E-commerce checkout payment receipt

“I'm building a checkout flow for my online store and need to generate a Pix BR Code for each order — for the next one, amount is R$89.90, my Pix key is my email contato@loja.com.br, business name is 'TechStore Brasil', city is 'Rio de Janeiro', and reference it as 'Order #5847'.”

Freelance invoice payment collection

“I just finished a project for a client and want to send them a Pix invoice they can pay instantly — I need the BR Code and QR image, my Pix key is my phone number, my business name is 'Consultoria Digital', the amount due is R$1200, it's from 'Brasília', and label it 'Invoice - Web Development Services'.”

When to prefer

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.

Side effects

Invalid or malformed Pix key format — returns error if key does not match CPF/CNPJ/email/phone/random UUID patterns

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
