Cost Estimate

Know the price before you generate

Get an exact cost breakdown before running any generation. Send the same parameters you would for a real request and get back the infrastructure cost, platform fee, and total -- without spending anything. Free to call.

How Cost Estimate Works

Cost Estimate returns an exact price breakdown for any generation request without actually running it. Send the same JSON body you would for a real generation -- model, prompt, dimensions, duration -- and the API returns the infrastructure cost, the 20% platform fee, and the total in both microdollars and human-readable format. The call is completely free and does not deduct any credits. Developers integrate cost estimation into their UIs to show users the price before they commit to a generation. Budget-aware automation systems use it to decide whether to proceed based on cost thresholds. Finance teams use it to forecast spending for planned content production. It is also useful during development for understanding how different models and parameters affect pricing. Call the estimate endpoint with the exact same parameters you plan to use for the real generation -- the cost depends on model, resolution, duration, and quality settings. Use it in your approval workflows: estimate first, show the user the cost, then generate only after confirmation. The response includes a quote ID that you can reference in the subsequent generation call for guaranteed pricing.

Frequently asked questions

Do I need a subscription to use Cost Estimate?
No. FairStack uses pay-per-use pricing. Add funds to your account and use any tool whenever you need it. There is no subscription, no monthly commitment, and no minimum spend.
What file formats does Cost Estimate support?
Cost Estimate outputs PNG, JPG, and WebP. You can download results instantly after generation. All outputs are full quality with no watermarks.
How long does Cost Estimate take?
Most generations complete in 2-10 seconds. Processing time depends on the complexity of your input and the selected quality settings. You can monitor progress in real time.
Can I use Cost Estimate outputs commercially?
Yes. All outputs generated on FairStack include a commercial-use license. You can use them in client work, products, marketing materials, social media, and any other commercial context.
What does the cost estimate response include?
The response includes infrastructure cost (what the GPU provider charges), platform fee (20% of infra cost), total cost in microdollars and USD, the model used, and a quote ID valid for 60 seconds. The breakdown is identical to what you would be charged on a real generation.
Is the cost estimate always accurate?
Yes. The estimate uses the same pricing engine as the generation endpoint. If you generate within 60 seconds using the returned quote ID, the price is guaranteed. After 60 seconds, re-estimate to get current pricing in case provider costs have changed.
Are there rate limits on the cost estimate endpoint?
The cost estimate endpoint is free and has generous rate limits. You can call it hundreds of times per minute for price comparison workflows. It does not count against your generation rate limit or deduct any credits from your balance.
