- call multiple providers through one consistent API
- keep request and response handling simpler
- track usage, latency, and price in one place
- change models or routing strategy without rebuilding your app
You can get started on
:free models with zero deposited credits. Paid models require available wallet balance.Why use a gateway
AI integrations become harder as soon as you need more than one provider, model, endpoint family, or deployment environment. Phaseo gives your app one stable integration layer. You can ship the product flow first, then adjust models, providers, routing, and pricing strategy without rewriting every caller.Core concepts
Unified endpoints
Use one API shape across text, image, moderation, audio, video, and provider-compatible routes.
Routing controls
Choose how requests move across providers for availability, cost, latency, region, and policy.
Usage and cost tracking
Track request volume, token usage, latency, and price so production behavior is visible.
BYOK (Bring Your Own Key)
Connect provider keys when you want provider billing and limits while keeping the same Gateway interface.
Recommended path
- Sign up for a Phaseo account.
- Generate an API key in your dashboard.
- Make your first request with the
/v1/responsesendpoint. - Choose your production path for SDKs, routing, observability, and rollout.
