Developer gateway
Relay is a multi-model AI API gateway for software developers. It is not a consumer proxy network, traffic anonymization service, or official reseller of foundation model vendors.
About ProxyStacks Relay
AI API gateway built for builders.
ProxyStacks builds and operates Relay, a multi-model AI API gateway. Developers buy prepaid service credits, call a unified API, and use included tools for keys, usage logs, rate limits, and billing. Backend capacity is procured from paid commercial cloud and AI API channels; we do not sell upstream vendor accounts or claim official reseller status for foundation models.
Managed model routes
Use Relay-issued keys to call Mini, Standard, and Advanced routes. We route approved workloads through paid commercial backend capacity and keep usage records in one dashboard.
Metered credits
Each request records the route, token counts, cost, status, and latency so you can reconcile usage against your prepaid credit balance.
Clear billing
Plans and top-ups add service credits for gateway usage. Waffo Pancake processes payments as merchant of record, including invoices and applicable indirect taxes.
Try the gateway before you scale.
Create an account, use trial credits, and inspect usage controls before upgrading.
