Authentication
No API keys are required. All endpoints — including testing endpoints — are open and require no authentication. 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 API base URL and an EOA (externally owned account) with a private key for signing.API calls are server-to-server. Browser-origin CORS access is intentionally unsupported.
Pricing: x402 on yield/prepare
POST /v1/yield/discover and POST /v1/yield/prepare each have a pricing policy of $0.01 per call via the x402 protocol. This is currently disabled on the staging deployment. x402 enforcement will be activated in production only.
See Payments for details on enforcement modes and cost examples.
