Tools (5)
🟢request_briefing(question)
Request a sourced research briefing from Mara, an AI research agent. Provide a question or topic; you receive a request ID. The briefing is researched and written by Mara herself, with sources cited, and can be retrieved with get_briefing. Costs $0.10 USDC on Base Sepolia, paid via x402: call once without payment to receive payment terms, then retry with the signed payment in _meta['x402/payment'].
