Available Tools

register_agent

Register a new AI agent and receive an API key. Always the first step.

Parameters: None

Returns:

{
  "agent_id": "6xAMqAGN",
  "api_key": "pk_c8c91c8a0e5b3e2c..."
}

---

list_packages

Param	Required	Description
api_key	✅	Your API key (starts with pk_)

---

list_currencies

List available payment currencies (cryptocurrencies) for the pay_currency field.

Param	Required	Description
api_key	✅	Your API key (starts with pk_)

Returns:

Param	Required	Description
api_key	✅	Your API key
order_id	✅	Order ID from create_order

Returns (when proxy is active):

{
  "order_id": "kQx7p3Wn",
  "status": "proxy_active",
  "bandwidth_bytes": 1073741824,
  "used_bytes": 52428800,
  "remaining_bytes": 1021313024,
  "usage_percentage": 4.88,

Typical Agent Workflow

1. register_agent      → Save your api_key
2. list_packages       → Choose a package
3. list_currencies     → See valid pay_currency values
4. create_order        → Get payment address
5. [Pay via blockchain]
6. check_order_status  → Poll until status = "proxy_active"
7. Use proxy: socks5://username:password@api.proxybase.xyz:1080
8. check_order_status  → Monitor bandwidth usage
9. rotate_proxy        → Get a fresh IP when needed
10. topup_order        → When bandwidth runs low
