## FAQ

### Which interfaces are available?

A documented REST API (OpenAPI) for products, companies, orders and leads, webhooks for changes, product feeds, BMEcat/OCI/cXML for procurement and an MCP server for AI agents.

### How do I get access?

You create API keys in the panel per company; public catalogue data is readable without a key, with a key higher limits apply. AI clients can additionally sign in via OAuth.

### How stable are the interfaces?

The API is versioned; deprecations are announced and come with a transition period. A Postman collection and examples make getting started easier.
