## Usage Notes

- Provider keys are not forwarded automatically. Set `WEAVIATE_PROVIDER_KEYS`
  to a comma-separated allowlist, for example `OPENAI_API_KEY,COHERE_API_KEY`.
- Set only the provider keys your collection configuration actually uses.
- If multiple providers are configured, include only those corresponding
  headers.
