Payments
Rhaios tools use a freemium model. Monitoring tools are free. Strategy tools require a small per-call payment via the x402 protocol.
| Tool | Cost | Category |
|---|
yield_prepare | $0.01 | Strategy and execution prep (deposit, redeem, rebalance) |
yield_execute | Free | Execution |
yield_status | Free | Monitoring |
yield_history | Free | Monitoring |
yield_execute is free to call but submits an on-chain transaction. Your smart wallet pays gas in USDC via the ERC-20 paymaster.
yield_prepare handles deposits, redemptions, and rebalances — all at the same 0.01price.Stagingenvironmentuses0.001 per call.
How x402 works
x402 is an open protocol for machine-to-machine payments. When your agent calls a paid tool:
- The server responds with HTTP
402 Payment Required and a payment request
- Your agent’s MCP client handles the payment automatically
- The tool executes and returns results
No manual payment setup is needed — x402-compatible clients handle it transparently.
Cost example
A typical deposit flow costs:
| Step | Tool | Cost |
|---|
| Get strategy + calldata | yield_prepare | $0.01 |
| Execute on-chain | yield_execute | Free (+ gas) |
| Check position | yield_status | Free |
| Total | | $0.01 + gas |
Runtime interoperability
If you are integrating Rhaios through a larger agent runtime, keep payment handling in the runtime layer and call Rhaios for yield-specific execution prep.
