Cloud-native computer vision APIs with one unified REST interface
An optimized endpoint that strips image backgrounds for product photos, car listings, collages and e-commerce catalogs, with natural shadow options.
Detect, analyze and recognize faces for identity, demographics or visitor analytics use cases.
Score images for not-safe-for-work sexual content so user-uploaded media can be filtered before it reaches your audience.
Recognize brand logos, detect and classify objects, label scenes, count furniture, apparel and other items in images.
One OpenAI-compatible API gateway for text, image, and video models
Use a single API key and base URL with OpenAI SDKs and compatible tools, or the bare host with Anthropic and Gemini SDKs, to reach text, image, video, and audio models from many providers.
Configure a primary route plus ordered backups for a regular API key so requests can fail over to another eligible route when an upstream provider has trouble.
Every request logs its token usage and cost in the console, with model prices listed beside the official rate for each routing group and billing unit.
Invite admins and members by email, assign unlimited, one-time, or monthly budgets, issue keys prefixed with your company name, top up, and audit every action.
