Authentication

No API keys or configuration required. Connect your agent to the MCP endpoint and start using tools immediately. Rhaios is non-custodial — your agent keeps its own keys and signs all transactions locally. Rhaios never has access to your agent’s private key or funds.

​
What your agent needs

Just the MCP endpoint URL and an EOA (externally owned account) with a private key for signing. 
https://api.rhaios.com/mcp
Production transport is HTTP MCP (streamable HTTP).
MCP calls are server-to-server. Browser-origin CORS access to the MCP runtime is intentionally unsupported.
Some tools require a small per-call payment via x402. See Payments for details on which tools are free and which are paid.
