"Invalid bearer token" when using Anthropic direct

[joesaunderson]

What happened

I have set ANTHROPIC_AUTH_TOKEN and ANTHROPIC_BASE_URL as per the docs (in .env.local within .deepsec directory.

I get:

Agent SDK error: Claude Code returned an error result: Failed to authenticate. API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"Invalid bearer token"},"request_id":"..."}

Reproduction

pnpm deepsec process --project-id ...

Expected vs actual

I expect the requests to work, they didn't.

Environment

• deepsec version (pnpm deepsec --version): 1.1.14
• Node version (node --version): v24.11.1
• OS: MacOS
• Agent backend (claude-agent-sdk / codex): claude-agent-sdk
• Model:

Try setting your "ANTHROPIC_API_KEY" as your key instead of the "ANTHROPIC_AUTH_TOKEN" in your .env.local

Have you tried running claude with the same env vars and it worked?

Docs need to be updated, should be ANTHROPIC_API_KEY
