Automation agencies and WhatsApp assistants

Your AI WhatsApp assistant does not need to see the customer's CPF.

Rota is an AI API in the OpenAI format that removes names, CPF numbers, phone numbers, emails and addresses from the message before the model. It works in automation tools that accept this format, such as n8n, and you pay in reais via Pix.

Why this matters to people who build assistants

The assistant of a clinic or an office receives names, CPF numbers, addresses and sometimes health data. The agency that builds the flow processes this data on behalf of its client.

Paying for AI in dollars with an international card adds the exchange rate and 3.5% IOF tax. At Rota, credit is in reais via Pix, from R$ 5.

To understand the intent of a message, answer questions and point to the next step, the model does not need the customer's documents.

How it works

  1. Change the AI address

    In your tool's OpenAI credential, use https://rota-nacional.ia.br/v1 as the base address and your Rota key.

  2. Choose the model

    Use a Rota ID, such as rota/rapido for short answers or rota/analise for conversations that need more reasoning.

  3. Rota cleans each message

    Before the model, names, CPF numbers, phone numbers, emails and addresses become placeholders. The model answers from the clean text.

  4. The flow completes the data

    When the reply needs the name or the booked time, the agency's flow fills it in afterwards, with the data that it already has.

Example with fictitious data

Before Rota

After Rota

Oi, aqui é o [PESSOA_1]. Quero marcar uma limpeza de pele para sexta à tarde. Meu CPF é [CPF_1] e meu e-mail é [EMAIL_1].

How to integrate
