What is claudeapi.com?

Claude API is a Claude-compatible API gateway that provides direct access to Anthropic models for developers and teams.

It supports the Anthropic SDK and OpenAI-compatible request formats, enabling migration by swapping base_url with no code changes.

Features include message-based endpoints, streaming responses (messages.stream), multi-region deployment, and intelligent routing to reduce latency.

Common use cases include chatbots, AI agents, content generation, and backend model serving with support for models such as claude-opus-4-7 and claude-sonnet-4-6.

Client examples and snippets for Python and curl show messages.create and streaming usage and provide integration and migration guidance.

Developer benefits include SDK compatibility, streaming text output, synchronized model updates with official releases, and dedicated developer support channels.
