Anthropic setup-token stopped working - "OAuth authentication is currently not supported"
✅Solved
Hey everyone,
My Anthropic setup-token suddenly stopped working today. I'm getting this error when trying to use any Claude model via the API:
Error: HTTP 404: not_found_error: Not Found
When I test directly with curl using Bearer auth, I get:
{
"type": "error",
"error": {
"type": "authentication_error",
"message": "OAuth authentication is currently not supported."
}
}
Setup:
- OpenClaw 2026.2.6-3 (updated today)
- Token type: sk-ant-oat01-... (from
Before the official OpenClaw update, I was using Claude Opus 4.6 by manually replacing the models.generated.js file from pi-ai@0.52.0 (downloaded from unpkg.com/@mariozechner/pi-ai@0.52.0/dist/models.generated.js). This worked perfectly with my setup-token.
After updating OpenClaw to 2026.2.6-3 today, even older models like Opus 4.5 don't work anymore - same OAuth error.
Anyone else experiencing this? Did Anthropic disable OAuth for their API?
