How this service works
Pay-per-call Brazilian business intelligence for AI agents, paid via x402 in USDC on Base.
Output
A JSON object containing the normalized CEP, street name (logradouro), city name, two-letter state abbreviation, and the IBGE numeric city code — e.g. {"cep":"38400100","street":"Avenida Floriano Peixoto","city":"Uberlândia","state":"MG","ibge":{"city":"3170206"}}.
Example use cases
E-commerce address autofill
“A customer just typed in CEP 01310-100 on checkout — can you look it up and give me the full street, city, and state so I can pre-fill the address form?”
Business data enrichment pipeline
“I have a list of Brazilian companies with only their postal codes. Can you resolve CEP 04578-000 and tell me what city and state it belongs to, including the IBGE city code?”
Logistics route planning
“I need to verify the delivery address for CEP 30112-020 — what street, city, and state does that postal code correspond to in Brazil?”
