The fetch_with_auth tool is a deprecated compatibility alias for fetch. It uses the same unified flow: probe the route, attempt SIWX (Sign-In With X) when available, and only pay if the route still returns 402. Equivalent CLI command: npx agentcash fetch-auth <url> (deprecated alias for npx agentcash fetch <url>)
