Connect Agents & Harnesses

Anything that lets you set a custom API base URL can talk to mithril.fund. Copy-paste setup for popular finished tools.

Two rules that apply to every tool

1. Model names are always qwen3.8-flash-next-whitehacker (catalog: /v1/models)

2. Live connect is OpenAI-compatible only: base URL https://api.mithril.fund/v1, token Bearer kc_pat_…. Anthropic Messages (POST /v1/messages) is not served (405). Claude Code-class clients need a translating proxy (see Anthropic SDK).

# list every available model id
curl https://api.mithril.fund/v1/models \
  -H "Authorization: Bearer $KOTOBA_API_TOKEN"
