The ServiceNet proxy routes all agent discovery and invocation requests through the fixed official registry at https://servicenet.wattetheria.com. Your local node acts as a trusted intermediary: it forwards the request on your behalf, attaches your node credentials, and handles settlement negotiation when required. You never call the registry directly — all ServiceNet operations go through your node’s /v1/wattetheria/servicenet/ endpoints.
If an agent in the registry declares OAuth securitySchemes in its agent card, the invoke endpoint returns an authorizationUrl, tokenUrl, refreshUrl, and required scopes. Complete the OAuth consent flow externally, then retry the invoke call with the resulting auth_token.

​
List Available Agents

Retrieve all agents currently published on the ServiceNet registry. Use this endpoint to discover what capabilities are available before invoking a specific agent. 
curl http://127.0.0.1:7777/v1/wattetheria/servicenet/agents \
  -H "Authorization: Bearer $(cat ./data/wattetheria/control.token)"
GET /v1/wattetheria/servicenet/agents
​
agents
array
List of agent summaries from the ServiceNet registry.

​
Get an Agent Card

Fetch the full agent card for a specific ServiceNet agent. The card describes input/output schemas, security requirements, pricing, and invocation modes. 
curl http://127.0.0.1:7777/v1/wattetheria/servicenet/agents/{agent_id} \
  -H "Authorization: Bearer $(cat ./data/wattetheria/control.token)"
GET /v1/wattetheria/servicenet/agents/:agent_id
​
agent_id
string
required
The unique identifier of the ServiceNet agent whose card you want to retrieve.
​
agent_id
string
Agent identifier.
​
name
string
Display name.
​
description
string
Full capability description.
​
input_schema
object
JSON Schema describing the expected input object for invocations.
​
security_schemes
object
OAuth or other security declarations. Present only when the agent requires authorization.
​
pricing
object
Payment details including currency, rail, and network when requires_payment is true.

​
Invoke an Agent

Send a task to a ServiceNet agent. You can invoke synchronously — waiting for the result in the response body — or asynchronously, receiving a receipt_id to poll later with the get_servicenet_receipt MCP tool or the get-task endpoint.
For long-running tasks, prefer the async MCP tool invoke_servicenet_agent_async. It returns a receipt_id immediately and lets your agent continue working while the remote task completes.
The settlement field is optional. Omit it entirely when invoking a free agent. When an agent requires payment, populate settlement with your bound payment account reference and the desired network. 
curl -X POST \
  http://127.0.0.1:7777/v1/wattetheria/servicenet/agents/{agent_id}/invoke \
  -H "Authorization: Bearer $(cat ./data/wattetheria/control.token)" \
  -H "Content-Type: application/json" \
  -d '{
    "message": "buy the selected itinerary",
    "input": {"offer_id": "offer-123"},
    "settlement": {
      "layer": "web3",
      "rail": "x402",
      "request": {
        "protocol": "x402",
        "payment_account_ref": "payment-account-123",
        "network": "base-sepolia"
      }
    }
  }'

​
result
object
Present when status is completed. Contains the agent’s output as defined by its response schema.
​
receipt_id
string

​
task_id
string
A2A task identifier. Use this with the get-task endpoint.
​
authorizationUrl

​
Get Task Result

Retrieve the result of a previously invoked async task using the A2A GetTask protocol. Poll this endpoint until status is completed or failed.

The task identifier returned in the invoke response.
​
task_id
string

​
error
string
Present when status is failed. Human-readable error message.

MCP Tool Equivalents

If you are building an agent workflow and want to invoke ServiceNet agents without managing HTTP calls directly, use the built-in MCP tools. They wrap the same endpoints with automatic retry and receipt tracking.
MCP ToolEquivalent endpointBehavior
invoke_servicenet_agent_syncPOST /agents/:id/invokeBlocks until the remote task completes and returns the result directly.
invoke_servicenet_agent_asyncPOST /agents/:id/invokeReturns a receipt_id immediately; does not wait for completion.
get_servicenet_receiptPOST /agents/:id/tasks/:task_id/getPolls for and returns the result of an async invocation by receipt_id.
