Billing

How billing works

Fixed price
Images, video seconds and characters are charged exactly as shown; the amount is known before the run starts.
By usage
Tokens and GPU time: credits are reserved when a run starts and settled to what it actually used when it ends. The rest of the reserve goes back to your balance.
Parameters
Prices on the website assume each model's default settings. API calls are priced for the parameters you send; fields you leave out use the provider's defaults.
Failed runs
Refunded to your balance automatically, unless a GPU-time run was stopped at its reserved time limit.
Smallest charge
0.01 credits ($0.0001) per run.

FAQ

Frequently Asked Questions

Straight answers on what things cost and how you pay.

Billing questions: info@railwail.com

How does pricing work?

You add prepaid balance in US dollars and every run is charged from it; 1 credit = $0.01. Images, video seconds and characters have a fixed price that is shown before you start. Token and GPU-time models reserve credits when a run starts and are settled to what it actually used.

Why can a run cost more or less than the example?

Examples use each model's default settings; chat examples use the request size shown in the table. More images per run, longer clips, higher quality tiers, longer prompts or longer answers cost more. The calculator and every model page show the price for your settings before you run.

Do API calls cost the same as the website?

Both use the same price rules. The website assumes each model's default settings; API calls are priced for the parameters you send, and fields you leave out use the provider's defaults. The same settings cost the same everywhere.

Can I try models without an account?

Yes, once per browser: FLUX.1 [schnell] and DeepSeek V4.1 Flash run without sign-up from the homepage. Everything else needs an account and balance.

Is there a free tier?

There is no free tier. Accounts created with Google get 10 trial credits ($0.10), usable 24 hours after sign-up, for runs of up to 2 credits and at most 5 runs per 24 hours. Email and GitHub sign-ups get no trial credits.

Is there a subscription or a minimum spend?

No subscription and no monthly fee. The smallest top-up is $5; a single run can cost as little as $0.0001.

What payment methods do you accept?

Cards, through Stripe Checkout. You are charged in US dollars. PayPal, SEPA transfers and payment by invoice are not available.

What happens when a run fails?

Failed runs are refunded to your balance automatically. The one exception is a GPU-time run that was stopped at its reserved time limit: the time it used is charged.

Do credits expire?

No, your credits never expire. Once purchased, they remain in your account until you use them.

Can I get a refund?

Yes, unused credits can be refunded within 14 days of purchase. Contact us at info@railwail.com.

Do you offer volume discounts?

For high-volume usage, contact us at info@railwail.com to discuss custom pricing.
