L LetzCNPJ QSA · Diff
Official history · Serpro / Receita

What changed in the QSA since the last official consult.

Every inquiry stores a Serpro payload snapshot. The next one shows the delta: officers and qualifications, registration status, address, share capital, company size, CNAE, phones, and email. Credit, legal, and KYC should not sign on a stale QSA.

For financial services, credit, legal, onboarding, and compliance. One credit per inquiry.

Why it matters

One stale QSA record can sink a contract or a loan.

What is on paper must match Receita. A partner who left, an officer who joined, capital that changed, or a status that is no longer Active — if the file does not follow, the risk sits on the contract, the credit, and the desk that signed.

On file

The contract, KYC sheet, and collateral still name the old board.

At Receita

The latest official consult already shows another partner, address, or capital.

The cost of lag

One wrong officer fact can jeopardize onboarding, KYC, a credit assignment, and contract enforcement.

How the diff works

Inquire. Snapshot. Delta. Routine.

The same QSA monitoring pattern finance teams already trust: we store the official JSON and compare it to the previous consult for that CNPJ.

01

Inquire at the source

Each inquire fetches the official Serpro QSA — officers, registration status, address, capital, size, CNAE, phones, and email.

02

We store the snapshot

The full payload stays on the company account, linked to the previous inquiry for that CNPJ. No snapshot, no history.

03

The next consult shows the delta

We compare the new JSON with the last one. What appeared goes into new changes; what left, into old. Officers, status, capital, address, and the rest of the registry.

04

Routines keep watching

Put the CNPJ on a scheduled routine. Each new inquire compares again — history grows with your process cadence.

Around the history

The platform that holds the diff.

The product is the history. API, credits, and isolation exist so credit and compliance can run that at scale.

Fields that actually move

Diff of the Serpro payload: officers and legal representative, registration status, share capital, address, size, headquarters/branch, CNAE, phones, and email.

Scheduled routines

Watch the book on weekdays, weekly, or cron. Each cycle is a new official consult — and a new delta.

Credit per inquiry

Each CNPJ inquired consumes one credit from the company account. No dummy price list: you pay the inquire that writes the snapshot.

API tokens

Per-account Bearer tokens, revocable. The JSON returns payload and changes — the same delta as the UI.

Per-company isolation

Snapshots, diffs, routines, and credits stay on that company account. Real multi-tenant boundaries.

Built for people who sign risk

Financial services, credit, legal, onboarding/KYC, and compliance — teams that cannot drift from Receita’s QSA.

For engineering

The same delta, over Bearer and OpenAPI.

Authenticate with Authorization: Bearer. Inquiries return the payload and the changes against the previous consult. Docs at /api-docs.

  • Per-account Bearer tokens, revoked immediately
  • OpenAPI/Swagger at /api-docs
  • dados + alteracoes match the web UI
