Pricing & Credits

The API is prepaid: you buy a credit balance, and each job deducts credits from it when it starts running.

For per-endpoint pricing, see sloyd.ai/api/pricing.

Buying credits

• Minimum purchase: $12, converted at 75 credits per $1 → 900 credits.
• Buy credits and manage auto-recharge from the API Dashboard's API Keys page.
• Auto-recharge, if enabled, tops up automatically once your balance falls to 750 credits, bringing it back up to 1,500 credits.
• Credits are a running prepaid balance, not a monthly allowance — they don't expire on a billing cycle.

When credits are charged

Cost is charged in credits when a job starts (not merely when it's requested), and refunded automatically if the job fails.

Insufficient balance

If a job's cost exceeds your remaining balance, the request fails with 402 Payment Required and the job is not started:

{
  "available": 12,
  "error": "Payment Required",
  "message": "Insufficient API credits",
  "required": 20
}

Top up from the dashboard and retry the same request — nothing is consumed on a failed attempt.

Ultra tier

Requesting targetFaceCount at or above 500,000 opts into the Ultra generation tier on image-to-3d / multi-image-to-3d / text-to-3d. If your account isn't yet configured for Ultra-tier billing, a request at this tier can return 402 even with a healthy prepaid balance. If you plan to use Ultra tier, contact us first so your account is set up for it.
