DataBR — API de Dados Públicos Brasileiros

Connects Claude to 122 Brazilian public data endpoints covering BCB (Selic, PTAX, Focus), IBGE (IPCA, PIB), CVM (fundos, fatos relevantes), B3 (equities, indices), Receita Federal (CNPJ), CGU compliance checks, TSE election data, STF/STJ decisions, INPE deforestation alerts, and ANEEL/ANP energy metrics. Uses x402 payment protocol with USDC on Base, so no API keys or registration. You pay per query (typically $0.003–$0.075) and the agent handles payment automatically. Good for building AI tools that need authoritative Brazilian economic data, company due diligence, regulatory compliance checks, or ESG analysis without upfront subscription costs. The Python SDK formats responses as LLM-ready context strings.
