OpenRouter Provider Initialization Error (400 Bad Request) #863
Description
I'm encountering an issue when trying to use the OpenRouter provider with opencode. I'm consistently receiving a 400 Bad Request error during message sending, indicating a ProviderInitError specifically for the openrouter provider. This happens even after ensuring my apiKey is correctly placed in the config.json.
failed to send message: POST

This is a bug because NPM package is not installed.
You can try
cd ~/.cache/opencodepnpm installsivaxreddy commentedon Jul 11, 2025
