Argus API

Your product runs on other people's APIs, and every one of them is a meter — tokens, credits, requests, rate limits. Argus reads them all into one place. This API is how you read Argus.

Query

Spend, balances, runway, and per-request costs over REST.

Send

Push per-call telemetry from your app — with the SDK or one signed POST.

Ask

Let agents watch your meters through the MCP server.

Make your first request

Everything lives under https://api.argus.town. Grab an API key from Settings → API keys in your dashboard, then ask for the overview — the same numbers the dashboard's front page shows:

curl https://api.argus.town/overview \
  -H "Authorization: Bearer argus_mcp_..."

You'll get back every meter Argus is watching for your workspace:

{
  "success": true,
  "data": {
    "total_mtd_usd": 438.12,
    "total_projected_usd": 754.53,
    "providers": [
      {
        "connection": { "id": "…", "provider": "openrouter", "status": "active" },
        "metrics": {
          "balance_usd": 96.72,
          "burn_per_day": 7.09,
          "days_to_zero": 13.6,
          "mtd_spend_usd": 179.71,
          "rate_limit_headroom_pct": 82,
          "accuracy": "exact"
        },
        "advisories": []
      }
      // … one entry per provider
    ],
    "daily_spend": [ { "day": "2026-07-19", "by_provider": { "openrouter": 12.4 } } ]
  }
}

That's the shape of the whole API: bearer key in, snake_case JSON out, always wrapped in { success, data }. Next: how credentials work.
