AXON gives AI agents safe access to paid services over x402. Operators get a live catalog of services, trust signals, and a governed runtime for 402 Payment Required spending. You can start on the hosted path with npx @axon402/init, or you can self-host the Decision API and dashboard with Live Onboarding.

​
The Problem

Autonomous agents now need to find, evaluate, and pay for real services using protocols like x402. Two things break the loop today:
  • Discovery is fragmented — no canonical place to browse paid x402 services with fresh prices, schemas, and trust signals.
  • Execution is unsafe — an agent with raw wallet access can drain its budget in minutes, pay unvetted endpoints, or sign transactions nobody reviewed until the bill arrives.

​
What AXON Does

Before every payment, AXON checks the agent’s mandate — daily budget, per-transaction cap, allowed hosts, blocked hosts, purpose alignment. If the request is safe, AXON signs the EIP-3009 payment on Base. If not, it denies, throttles, or escalates to a human. Every decision and receipt is stored. Every denial is explainable. Every approval flow has replay protection and expiry.

Hosted Runtime Quickstart

Bootstrap a governed agent on the hosted path with npx @axon402/init.

Self-Hosted Live Onboarding

Bring up Supabase, the Decision API, and the dashboard on your own infrastructure.

Operations

Deployment, auth, security, runbook, and webhook guidance for launch and ongoing operations.

​
Launch Posture

  • Hosted path is the fastest way to go live with governed agent spending.
  • Self-hosted path is for teams that need their own infra, secrets boundary, and operational control.
  • Runtime and operator are separate surfaces. Runtime keys are wallet-scoped. Operator work lives in the dashboard, axon-op, or the operator MCP surface.

Core Concepts

Organizations, wallets, mandates, and spend lifecycle.

Integrations

Runtime MCP, REST integration, OpenClaw, and two-surface IDE setup.

API Reference

Decision API endpoints, MCP tools, and error codes.

CLI

@axon402/init for hosted runtime bootstrap and axon-op for control-plane operations.

What This Repo Ships

​
When You’d Use This

  • Research agent buys $0.35 market snapshots from a paid x402 API — AXON enforces a $25/day cap and blocks unknown providers
  • Coding agent needs premium LLM inference — AXON checks the mandate allows api.openai.com and the request stays under the per-transaction limit
  • Autonomous workflow runs overnight — AXON requires human approval for anything above $1.50, and the approval token expires in 5 minutes
  • Multi-agent org with 10 agents — each has its own wallet, its own mandate, and the treasury vault funds them via auditable transfers

​
The x402 Payment Flow

Total AXON latency: < 200ms (policy + signing)

Supported Networks

Public launch docs only describe the current GA payment path: USDC on Base. Do not plan mainnet Ethereum or Arbitrum production rollouts from this site yet.
