Infomais is Serasa Experian's data-enrichment service (MS Data Delivery). Request exactly the attributes you need for a CPF or CNPJ and pay only for those. People attributes cover identity (name, birth date, mother's name, RG), contacts (addresses, phones, e-mails), profiling (income, social class, mosaic, purchasing power, scholarity), marketing affinities (credit card, personal credit, e-commerce, travel, smartphone, investments) and compliance (PEP, NIS, Bolsa Família, federal employee). Organization attributes cover registration (business and fantasy names, opening date, legal nature, CNAE, status), contacts, sizing (presumed revenue, company size, employee range, social capital, Simples Nacional), governance (partners, legal representative, board, social composition) and compliance (Sintegra, CCM, Suframa, cadastral situation).

Two reverse-lookup endpoints find a document from partial data — a name plus a city, a phone, an address — for people and organizations, and a lighter filter endpoint identifies records by name, UF and date. The distributor variant is supported through the distributor_type and distributor_dw parameters. Authentication is OAuth2 client credentials issued at developer.serasaexperian.com.br; the reverse-lookup endpoints also require a user token.

5 tools expose this connector's capabilities to your AI agent.

enrich_organization

`attributes` is a JSON array or a comma list; only the names the organization endpoint supports are accepted, so a typo is reported rather than silently ignored. The response mirrors the requested attributes — request exactly what you need, since each attribute is a billable item. Useful combinations: ["businessName","fantasyName","openingDate","legalNature","cnae","registrationStatus"] for registration; ["addresses","phones","email"] for contacts; ["presumedRevenue","companySize","employeeRange","socialCapital","simplesNacional"] for sizing; ["businessPartners","legalRepresentative","boardAdministrator","socialComposition"] for governance; ["sintegra","ccm","suframa","cadastralSituation","operationalIndicator"] for compliance; ["matrizFilial","branchsCount","codIBGE"] for structure. `indirect_sale_document` is accepted only on the distributor variant. Enrich a CNPJ with the requested Infomais attributes: registration, partners, revenue and more

enrich_person

`attributes` is a JSON array or a comma list; only the names the person endpoint supports are accepted, so a typo is reported rather than silently ignored. The response mirrors the requested attributes — request exactly what you need, since each attribute is a billable item. Useful combinations: ["name","birthDate","motherName","gender","maritalStatus","rg"] for identity; ["addresses","phones","email","emailValidado"] for contacts; ["income","socialClass","mosaic","purchasingPower","scholarity","profession"] for profiling; ["afinidadeCartaoCredito","afinidadeCreditoPessoal","afinidadeEcommerce",...] for marketing affinities; ["pep","nis","bolsaFamilia","federalGovEmployee"] for compliance checks. `distributor_type` and `distributor_dw` apply only to the distributor variant of the product; leave them unset otherwise. Enrich a CPF with the requested Infomais attributes: name, contacts, income, affinities and more

filter_enrichment

Infomais answers with the document it resolved plus name, age, city, neighborhood and uf — use it to validate a document before calling enrich_person or enrich_organization. This endpoint also requires a user token: set `user_token`. Resolve loose data about a person or organization to candidate documents

find_organization_by_keys

The endpoint is `enrichments/organizations/retrieve` and it requires a user token in addition to the client token — set `user_token` to the USER token issued for your application. `response_limit` caps the number of candidates. Find CNPJs matching partial data — corporate name, CEP, phone — without knowing the document

find_person_by_keys

The endpoint is `enrichments/person/retrieve` and it requires a user token in addition to the client token — set `user_token` to the USER token issued for your application. `response_limit` caps the number of candidates. Find CPFs matching partial data — name, address, phone, birth date — without knowing the document

Enrich this lead: CPF 12345678901. I need name, contacts and marketing affinities.

Calls enrich_person with document 12345678901 and attributes ["name","birthDate","addresses","phones","email","afinidadeCartaoCredito","afinidadeEcommerce","socialClass","mosaic"], returning only the requested attributes.

I have a company name and a city but no CNPJ — can you find it?

Calls find_organization_by_keys with corporate_name and city plus your user_token, returning candidate organizations with their documents so you can then enrich the right CNPJ.

Check the registration status and partners of CNPJ 33014556000196.

Calls enrich_organization with document 33014556000196 and attributes ["businessName","registrationStatus","cadastralSituation","businessPartners","legalRepresentative"].

Only the ones you will use — Infomais bills per requested attribute. The connector rejects attribute names the endpoint does not support, so a typo fails loudly instead of returning a partial record you pay for without noticing.
