Usage, Quotas & Billing Plans in Argus

Argus enforces a monthly event quota per organization. Every error event your SDK sends counts toward that quota. Understanding your usage — and knowing what happens when you approach the limit — helps you plan ahead and choose the right plan before you hit a wall in production.

Plans

Plan	Events / month	Projects	Price
Free	10,000	1	$0
Pro	500,000	Unlimited	$10/mo

The Free tier is limited to 1 project. If you need to monitor multiple applications or environments, upgrade to Pro for unlimited projects.

How quotas work

Argus enforces your quota atomically at the ingest layer — every incoming event is checked and counted in a single operation before it is accepted. This design means:

No silent overages. Argus cannot accept more events than your plan allows, even under a sudden burst of traffic.
HTTP 429 on limit reached. When your organization exhausts its monthly quota, the ingest endpoint returns 429 Too Many Requests. Events sent after this point are dropped.
SDK behavior. The Argus SDKs treat 429 responses silently — they drop the event, do not retry, and do not throw an error into your application. Your app continues running normally; only Argus capture stops.
Monthly reset. Your quota resets automatically at the start of each calendar month (UTC). You do not need to take any action.

Viewing your usage

Open the Usage page in the Argus dashboard to see a live snapshot of your organization’s current-month consumption:

Used / Limit — total events ingested this month versus your plan’s monthly ceiling.
Breakdown by level — how your event count is split across errors (ERROR + FATAL), warnings (WARNING), and info (INFO + DEBUG).
Current plan — which plan your organization is on and a shortcut to upgrade.

Usage API

Fetch your current usage programmatically with a single endpoint:

GET /api/v1/usage
Cookie: session=YOUR_SESSION_COOKIE

Example response:

{
  "statusCode": 200,
  "status": "success",
  "message": "Usage fetched",
  "data": {
    "plan": "FREE",
    "used": 7430,
    "limit": 10000,
    "month": "2025-07",
    "breakdown": {
      "errors": 6100,
      "warnings": 920,
      "info": 410
    }
  }
}

Field	Type	Description
`plan`	`"FREE"` \| `"PRO"`	The organization’s current plan
`used`	number	Events ingested so far this calendar month
`limit`	number	Monthly event ceiling for the current plan
`month`	string	The current billing month in `YYYY-MM` format
`breakdown.errors`	number	Count of ERROR and FATAL events this month
`breakdown.warnings`	number	Count of WARNING events this month
`breakdown.info`	number	Count of INFO and DEBUG events this month

Upgrading to Pro

When you are ready to raise your limit or add more projects, upgrade directly from the dashboard:

Open the Billing section

Click Usage or Billing in the dashboard sidebar. Your current plan and usage meter are displayed at the top of the page.

Click Upgrade

Click the Upgrade button. Argus redirects you to a secure, hosted checkout with Polar, our payment provider.

Complete checkout

Enter your payment details in Polar’s checkout. On successful payment, a webhook flips your organization to Pro within seconds — no restart required.

Confirm your new limits

Return to the Usage page. Your plan now shows PRO, your limit is 500,000 events/month, and the 1-project restriction is removed.

To change your payment method or cancel, open Billing in the dashboard and click Manage subscription — this opens the Polar customer portal. For the full usage endpoint reference, see the Usage API reference.
