Frequently asked questions

How is Microsoft pricing handled on Railwail?
Railwail uses transparent per-call or per-token credit pricing for all Microsoft models. You pay only for what you use — no monthly minimums, no upfront commitments. Pricing for every individual Microsoft model is shown on its detail page.
Are there rate limits when using Microsoft via Railwail?
Default rate limits depend on your account tier and the underlying Microsoft 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 Microsoft support through Railwail?
Microsoft 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 Microsoft models?
Yes — every new Railwail account receives free credits that work across all providers, including Microsoft. No credit card is required to start. You can try every model in the catalog before committing to a paid plan.
