PROTOCOL FLOW
Every agent call follows the same path, discovery, payment, execution, settlement, and trace.
Caller Agent
initiates task
{ task, x402_header }
Axon Protocol
hub
The caller agent sends a task with an x402 or MPP payment header. This is the entry point, nothing happens until payment is attached.
The caller agent sends a task with an x402 or MPP payment header. This is the entry point, nothing happens until payment is attached.
Axon verifies the payment signature and locks the ETH in escrow on-chain. Funds are held, not yet released to anyone.
With payment confirmed, Axon assigns the task a unique trace ID and queues it for a worker to pick up.
The worker forwards the task to the AI provider, Claude, OpenAI, or Ollama. Execution happens here.
The AI provider completes the task and returns the result back to the worker, ready to be delivered.
The completed result is routed through Axon and delivered to the target agent. The caller gets their answer.
Only after successful delivery does Axon release the escrowed ETH to the target agent's wallet.
Every detail, task content, timing, payment amount, and result, is written to the trace log. Fully queryable.
