Boleto.Cloud
Boleto.Cloud generates and manages Brazilian boletos (bank payment slips) across multiple banks through a single REST API, covering single issuance (POST /boletos, returning a ready PDF), batch issuance (up to 300 per request), and installment-plan (carnê) generation, plus automatic bank registration via banking API or CNAB file and status lookups. Requests authenticate with HTTP Basic Auth using an API key against separate sandbox (sandbox.boletocloud.com) and production (app.boletocloud.com) hosts. The free plan supports unlimited (volume-capped) boleto issuance with no monthly fee since Boleto.Cloud never intermediates payments; paid plans start at R$35/month for higher volume and lower per-boleto rates, and a live Origin-header probe found no Access-Control-Allow-Origin header on either GET or OPTIONS requests.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
