Frequently asked questions
How is Runway pricing handled on Railwail?
Railwail uses transparent per-call or per-token credit pricing for all Runway models. You pay only for what you use — no monthly minimums, no upfront commitments. Pricing for every individual Runway model is shown on its detail page.
Are there rate limits when using Runway via Railwail?
Default rate limits depend on your account tier and the underlying Runway capacity. Free-tier accounts get sensible defaults for development; paid accounts can request higher limits. Contact support if you need dedicated throughput or burst capacity.
Which regions does Runway support through Railwail?
Runway models are served from Railwail's globally distributed edge infrastructure. EU, US, and Asia-Pacific traffic is automatically routed to the nearest available provider region. GDPR-compliant EU-only routing is available on request.
Is there a sandbox or free tier to test Runway models?
Accounts created with Google get 10 trial credits ($0.10), usable 24 hours after sign-up for runs of up to 2 credits each, so you can test the cheaper Runway models. Email and GitHub sign-ups start without trial credits. No credit card is required to sign up.
