| Tool | Description | Behaviour |
|---|---|---|
| keryx_status | Describe this MCP surface, its payment behavior, and the active caller tier. | Read-only |
| research | Research a question under a USDC creator-payment budget. Keryx selects sources, pays access tolls and weighted citation rewards on the configured Arc network, then returns qualified source excerpts and a receipt. Complete synthesis and per-assertion entailment remain unverified. This remote surface uses Keryx's treasury; anonymous research is sponsored, not caller-funded usage. Public research may send your question to our search provider. The source USDC budget is separate from model and search operating costs. | Changes data |
| research_monthly | Read the four-request, 30-day Research Monthly quote and handoff. The current quote identifies its payment network. Never buys or redeems a plan. | Read-only |
