INVALID_API_KEY

API key is invalid or malformed. Check for typos — keys have prefixes like wa_, cl_, sk_, ei_, eu_.

Remediation

How to fix

  1. Copy the key again from console.aethar.dev — avoid trailing whitespace
  2. Confirm the key prefix matches the API you're calling (wa_ = WageAPI, cl_ = CostAPI, etc.)
