Authentication

ASG uses API keys for authentication. Create a key in the Console, set it as an environment variable, and include it as a Bearer token in every request.

Quick Setup

Create an API key at agent.asgcompute.com/console → API Keys → Create Key
Set your environment variable:

export ASG_API_KEY="sk-agent-..."

Include in requests:

Authorization: Bearer $ASG_API_KEY

Verify Connectivity

Test with a free tool — no payment required:

curl -s https://agent.asgcompute.com/v1/mcp/tools/call \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $ASG_API_KEY" \
  -d '{"tool": "get_status", "arguments": {}}'

import os, requests

response = requests.post(
    "https://agent.asgcompute.com/v1/mcp/tools/call",
    headers={
        "Content-Type": "application/json",
        "Authorization": f"Bearer {os.environ['ASG_API_KEY']}",
    },
    json={"tool": "get_status", "arguments": {}},
)
print(response.json())

const response = await fetch('https://agent.asgcompute.com/v1/mcp/tools/call', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${process.env.ASG_API_KEY}`
  },
  body: JSON.stringify({ tool: 'get_status', arguments: {} })
});
console.log(await response.json());

Key Security

Never share your API key. Treat sk-agent-* keys like passwords. If compromised, revoke immediately in the Console and create a new key.

Practice	Recommendation
Storage	Environment variable or secrets manager — never in source code
Rotation	Rotate keys periodically; revoke unused keys
Scope	Each agent/integration should use its own key
Monitoring	Check usage in the Console to detect anomalies

Auth vs. Payment

ASG separates authentication (who you are) from payment (how you pay):

Concern	Mechanism
Identity	API key via `Authorization: Bearer <api_key>`
Payment	Solana USDC via 402 quote → on-chain transfer → `X-Payment` header

Free tools (get_status, echo, sandbox_cancel) require only authentication — no payment step.

MCP-Native Integration

For MCP-compatible agent frameworks, use the JSON-RPC endpoint (/mcp) with the same Bearer header:

curl -s https://agent.asgcompute.com/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $ASG_API_KEY" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/list"
  }'
