ANTHROPIC_BASE_URL / ANTHROPIC_AUTH_TOKEN

Set the two environment variables below and Claude Code talks to this endpoint instead of Anthropic directly. Because the Anthropic Messages protocol is terminated natively, tool use and long-context sessions behave normally. Model names must be the ids from the catalogue, not Anthropic's aliases.

Code

export ANTHROPIC_BASE_URL="https://starseaapi.com"
export ANTHROPIC_AUTH_TOKEN="sk-your-key"
claude  # then pick a model from the catalogue

Quickstart

1. Create an API key — Sign up, then create a token in the console. A key works across the whole catalogue; scope and quota can be restricted per key.
2. Point your client at the endpoint — Set base_url to https://starseaapi.com/v1 and use the key. Any OpenAI-compatible SDK, IDE or desktop client works.
3. Pick a model — Start with a low-cost tier for prototyping. Every id in the catalogue can be swapped without touching code.
4. Watch cost, not just quality — Output tokens are usually priced at a multiple of input, and reasoning models emit thinking tokens. Keep stable prompt prefixes first so caching applies.
