Use every model from one wallet
Give developers one account, one credit balance, one API key and one usage history across text, image, video and music generation.
The multimodal API layer for developers
Access video, image, music and LLM models through one API.
API-Key lets customers try models in the browser, create API keys, and ship the same model capabilities to their own users with a managed gateway, credit wallet and task system.
One account. One wallet. One API key. Browser playgrounds and production endpoints share the same model gateway.

OpenAI-compatible developer surface
Browser playground
Let customers try models before they call the API.
The web console stays connected to the same credit system and media workflows as the developer API. A workflow that works here can be exposed to end users through API keys.
Generate and edit commercial visuals.

Developer API
Turn every model into a product-ready API for your customers.
Consumers can generate keys, call compatible routes, submit async media tasks, poll results, track usage and pay from one credit balance. The gateway turns model capabilities into a developer product.

Why managed model routing matters
Direct integrations become a managed API platform.
API-Key adds the product controls needed to sell model access: keys, channels, model groups, retries, billing settlement and logs.
Turn playground output into production APIs
Customers can test models inside API-Key, save their best workflows, then call the same capabilities from their own products.
Route by model, group and channel health
A managed API layer maps public model names to channels with priority, weight, retry and auto-disable controls.
Store generated media for real apps
Async image, video and music tasks return trackable records and durable result links instead of short-lived temporary URLs only.
From demo to API revenue
The same capability works for your UI and your customers' apps.
01
Try a model in the browser
Use the visual playground for images, video and music, or call chat and embeddings through API examples.
02
Create an API key
Generate consumer keys with model limits, group routing, IP allowlists and usage tracking.
03
Route through gateway channels
Map a public model to delivery channels with model overrides, retry policy and health-based failover.
04
Bill and deliver results
Reserve credits, refund failed tasks, expose durable result links and task records to your product.
