coinbase/query-onchain-data

Consulte dados on-chain na Base usando a API SQL da CDP via x402. Use quando você ou seu usuário quiser visualizar informações on-chain sobre blocos, transações e eventos decodificados.

O que é query-onchain-data?

Esta skill permite consultar dados on-chain na blockchain Base utilizando a API SQL da Coinbase Developer Platform (CDP) com o protocolo de pagamento x402. Ela é particularmente útil para desenvolvedores e agentes de IA que precisam obter informações decodificadas sobre blocos, transações e eventos de forma programática. Compatível com plataformas como Claude Code, Cursor e Codex, a skill converte consultas em linguagem natural para chamadas SQL à API CDP, processando e retornando os dados on-chain em formato estruturado. Seu funcionamento baseia-se na documentação SKILL.md, que guia o agente a autenticar via x402, formular consultas SQL apropriadas e interpretar os resultados, facilitando a análise de contratos inteligentes, rastreamento de transações e monitoramento de eventos sem necessidade de um nó completo.
