Frequently asked questions
How is Custom Providers pricing handled on Railwail?
Railwail uses transparent per-call or per-token credit pricing for all Custom Providers models. You pay only for what you use β no monthly minimums, no upfront commitments. Pricing for every individual Custom Providers model is shown on its detail page.
Are there rate limits when using Custom Providers via Railwail?
Default rate limits depend on your account tier and the underlying Custom Providers 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 Custom Providers support through Railwail?
Custom Providers 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 Custom Providers 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 Custom Providers models. Email and GitHub sign-ups start without trial credits. No credit card is required to sign up.
