Billing & credits

Renders are metered with credits, deducted from your workspace’s balance on every successful render.

Cost per render

A standard render costs 10 credits, regardless of image size, format, or which layer types you use.

Plans

Plan	Monthly credits	≈ renders/month	Watermark
Sandbox Free	150	~15	Yes, forced on every render
Starter	5,000	~500	No
Growth	25,000	~2,500	No
Scale	100,000	~10,000	No

Unused monthly credits don’t roll over. You can also purchase one-off top-up credit packs, which are consumed only after your monthly allowance runs out.

On the Sandbox Free plan, every render is watermarked server-side — this is enforced in the render pipeline itself, not just the client SDKs, so there’s no request parameter that can suppress it. Upgrading removes the watermark going forward.

Checking your balance

Every successful render response includes a billing block (JSON responses) or X-Drawtab-Credits-Remaining / X-Drawtab-Renders-Remaining headers (binary responses) — see POST /v1/render. There’s no separate “check my balance” endpoint yet; read it off the response of your last render, or check the dashboard.

Running out of credits

A render attempted with insufficient balance returns 402 before any rendering happens — you are never charged for a render that didn’t complete:


{
  "success": false,
  "error": "Insufficient credits (0 credits / ~0 renders remaining, 10 credits required per render).",
  "paywall": {
    "required": true,
    "reason": "CREDITS_EXHAUSTED",
    "balance": 0,
    "rendersRemaining": 0,
    "upgradeUrl": "/dashboard/billing",
    "message": "Credits depleted. Upgrade your subscription or top up credits to continue rendering unbranded graphics."
  }
}

Top up or upgrade from Billing in the dashboard .

Relationship to rate limits

Credits and rate limits are independent controls. Running low on credits doesn’t relax your rate limit, and staying under the rate limit doesn’t protect you from running out of credits. Both are checked on every request.
