Question
Hi, thanks for your great work!
I'm trying to use opencode with Claude via a custom API endpoint. The same configuration works fine with Claude Code, but opencode returns the error: Not Found: Route /api/messages not found.
Environment Variables (working with Claude Code)
export ANTHROPIC_BASE_URL="my_url"
export ANTHROPIC_AUTH_TOKEN="my_key"
opencode Configuration
~/.local/share/opencode/auth.json:
{
"anthropic": {
"type": "api",
"key": "my_key"
}
}~/.config/opencode/opencode.json:
{
"$schema": "https://opencode.ai/config.json",
"provider": {
"anthropic": {
"options": {
"baseURL": "my_url"
}
}
}
}Error logs:
