QI Tech Banking and Lending as a Service API
REST API for Banking as a Service (digital and escrow accounts, Pix, TED, boletos, cards, DDA) and Lending as a Service (debt issuance, simulation, formalization), served from the shared BaaS/LaaS host per the docs. Production and sandbox hosts are stated in the host table at https://docs.qitech.com.br/documentation/introducao_api_reference (sandbox: https://api-auth.sandbox.qitech.app). QI Tech publishes no machine-readable contract (no OpenAPI/AsyncAPI/GraphQL found on the docs or API hosts).
