brazilayer

Brazilian public data for AI agents — paid per call, no signup, no API keys.

Query the full Brazilian company registry (69M companies), screen against every official sanction list, and pull government contracts — from official sources (Receita Federal, CGU, MTE, PNCP), as clean JSON. Your agent pays per request ($0.005–$0.02) in USDC on Base via the x402 protocol.

Ideal for KYB, AML and counterparty due diligence on Brazilian entities — including crypto exchanges, OTC desks and fintechs onboarding Brazilian companies.

pip install brazilayer

Quick start

from brazilayer import Brazilayer

bl = Brazilayer()          # no wallet: free samples only
bl.amostra_cnpj()          # learn the response format, free

bl = Brazilayer(private_key="0x...")   # wallet with a few USD of USDC on Base
bl.empresa("00.000.000/0001-91")       # registration card         $0.005
bl.integridade("00000000000191")       # sanctions screening       $0.01
bl.contratos_fornecedor("00000000000191")  # public contracts won  $0.01
bl.buscar_empresas(nome="padaria", uf="RJ")  # company search      $0.01

Payment is automatic: on HTTP 402 the client signs a USDC authorization (EIP-3009, gasless for you) and retries. One call ≈ 2 seconds end to end.

⚠️ Use a dedicated wallet with a small budget — a few dollars covers hundreds of calls. Never your main wallet.

LangChain

from brazilayer.langchain import get_tools   # pip install 'brazilayer[langchain]'
tools = get_tools(private_key="0x...")       # 29 StructuredTools, agent-ready

CrewAI

from brazilayer.crewai import get_tools      # pip install 'brazilayer[crewai]'
tools = get_tools(private_key="0x...")
