Turn x402 endpoints from report-like previews into agent-loved decision JSON that says pay, skip, cap, retry, or fallback.

Run a cross-source research survey across arXiv, NIH grants, ClinicalTrials.gov, and GAO reports with one production-backed x402 workflow.

Three production-backed skills for agents that integrate, pay, and sign: discovery audit, payment-error diagnosis, and EVM transaction safety.

Explain, simulate, and risk-scan EVM transactions/tokens before an agent signs or recommends an on-chain action.

Turn x402/AP2/ACP/MPP/MCP payment failures into a likely cause, retry policy, and exact fix path.

Audit an agent/API origin for well-known discovery, x402 pricing, OpenAPI/MCP readiness, and install blockers before an agent integrates it.
