Hi Product Hunt! I’m Tang, the maker of Keryx. I’m building a research agent where you can inspect both the evidence and the money decisions. Give Keryx a question and a budget, then follow why it buys, skips or reuses a source. Results include source excerpts, article versions and receipts. Eligible citations that pass the evidence checks can reward creators in USDC on Arc. You can start with a free web trial or connect your own agent through MCP or the API. Writers can prove ownership of their feed and choose how their work is offered. This is early access. Keryx shows evidence gaps and incomplete answers, and the Windows Operator client remains an alpha. I’d love feedback from researchers, agent builders and independent writers: what evidence or payment details would make you trust a research agent?
