Use any model with Claude Code

Claude Code speaks the Anthropic API, and CompanyFabric exposes /v1/messages alongside the OpenAI-compatible endpoint. Override the base URL and every model in the library becomes available to your agent — including non-Anthropic ones through the messages translation layer.

Step by step

Setup

  1. 1

    Set the base URL and your CompanyFabric key in your environment:

    export ANTHROPIC_BASE_URL="https://api.companyfabric.com"
export ANTHROPIC_API_KEY="$COMPANYFABRIC_API_KEY"
  2. 2

    Pick the model per session (any catalog id works):

    claude --model anthropic/claude-sonnet-4-5
# or route to a different provider through the same key:
claude --model openai/gpt-5.5
  3. 3

    Verify billing: every turn's exact cost appears in your CompanyFabric dashboard usage feed.

FAQ

Frequently asked questions

Does subscription-based Claude Code work with a gateway?

Gateway routing applies to API-key usage. If you use a Claude subscription, keep it — add the gateway for overflow, other models, or team keys with spend caps.

Can I cap what Claude Code spends?

Yes — per-key budget caps are set in the dashboard; the key stops at the cap instead of surprising you at invoice time.
