Agents can optionally be monetized using a pricing model. If a pricing object is provided, the runtime ensures that the client submitting a request has transferred the required funds on the Solana blockchain before processing the request. The Runtime also enables configuring payments to the Agent, to get paid for the tasks performed, by checking if the message from the client includes a transaction signature on the Solana blockchain, transferring enough funds to the Agent. To enable pricing, all that is needed is giving the Runtime a Pricing object that contains the payment size needed in SOL, and the Agent wallet address: 
pricing = Pricing(
    wallet_address=agent_wallet_address,
    cost=0.1, # 0.1 SOL
)

runtime = AgentRunTime(
	inputs=[my_client],
	outputs=[my_client],
	agent=agent,
	pricing=pricing,
)
When pricing is forwarded, the runtime:
  • checks if the incoming messages from the inputs contain a Solana transaction signature. The signatures can be either just a signature string or a link to Solscan.
  • Verifies that the transaction transferred the required amount of SOL.
  • Only forwards the Message to the agent if the payment is valid.
