API Key Header Forwarding (#2)
Fixed critical bug where API keys passed via request headers were not being properly forwarded to the Anthropic API, causing authentication errors when running without ANTHROPIC_API_KEY environment variable.
Problem:
- Case-sensitivity bug where duplicate API key headers were sent
- When headers like 'X-Api-Key' were sent, they were preserved AND a new 'x-api-key' header was added
- Duplicate headers caused authentication failures with Anthropic API
Solution:
- Remove all variations of API key headers (case-insensitive) before adding normalized 'x-api-key'
- Add debug logging to trace API key extraction and header setup
- Add maskAPIKey helper function for secure logging
- Update ExtractAPIKey, SetupAuthHeader, and CreateHeadersMap functions
Technical Details
- Fixed in internal/client/anthropic.go
- All tests pass, golangci-lint clean
- Proper handling of Authorization, X-Api-Key, and anthropic-api-key headers
