Everything you need to ship with AI

A single, dependable gateway that abstracts away providers, keys, and billing.

Unified gateway

One OpenAI-compatible endpoint in front of every provider. Swap models with a string change.

Prepaid wallet

Top up once and spend across any model. No surprise invoices, no per-provider minimums.

Multi-model, single key

Issue one platform key and reach Codex, Claude, DeepSeek and Grok from the same base URL.

Transparent pricing

See exact per-1M-token input and output prices with the markup shown up front.

Streaming built in

Full Server-Sent Events streaming for chat completions, compatible with the tools you already use.

Automatic failover

Weighted routing across credentials keeps requests flowing when an upstream provider degrades.

Every frontier family, one endpoint

Mix and match the right model for each task without changing your integration.
