Which API forms does Claude Opus 5 support, and how do I call it through Wokey?
Claude Opus 5 supports /v1/messages (Messages requests). Set the API base URL to https://api.wokey.ai, authenticate with a Wokey API key, and use the canonical model ID claude-opus-5; you can start with /v1/messages. The Send a request section includes a curl example for every supported API form.
How do I use Claude Opus 5 in Claude Code?
Claude Code calls Claude Opus 5 over /v1/messages. Set ANTHROPIC_BASE_URL="https://api.wokey.ai", ANTHROPIC_AUTH_TOKEN to your Wokey API key, and ANTHROPIC_MODEL="claude-opus-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 Opus 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.

How does calling Claude Opus 5 through Wokey differ from OpenRouter?
Wokey lists Claude Opus 5 at $0.75 input / $3.75 output per 1M tokens, against an official reference of $5 / $25. OpenRouter states it adds no markup on inference and charges its fee when you buy credits (5.5% by card). Wokey carries a curated set of models and has no per-provider routing parameters, so OpenRouter fits better if you need a wider catalog. The OpenRouter alternative page has the full comparison.
