Which API forms does Claude Sonnet 5 support, and how do I call it through Wokey?

Set the API base URL to https://api.wokey.ai, authenticate with a Wokey API key, and use the canonical model ID claude-sonnet-5; you can start with /v1/messages.

Claude Code calls Claude Sonnet 5 over /v1/messages. Set ANTHROPIC_BASE_URL="https://api.wokey.ai", ANTHROPIC_AUTH_TOKEN to your Wokey API key, and ANTHROPIC_MODEL="claude-sonnet-5", then start claude. Claude Desktop also uses /v1/messages; the setup guides cover both step by step.
What are the context window and maximum output for Claude Sonnet 5?
The catalog context window is 1,000,000 tokens and the maximum output is 128,000 tokens. These are separate limits, and a request must also satisfy the upstream constraints in effect when it is processed.
