kunji

Kunji validates API keys concurrently across dozens of services. It auto-detects the provider, checks key validity, extracts account metadata where supported, and exports results in multiple formats.

Note: For detailed usage examples for each provider, see USAGE.md

Features

• Auto-Detection — Identifies providers via prefix trie and regex fallback
• Concurrent — Worker pool with configurable thread count
• Metadata Extraction — Balance, account name, and email for valid keys
• Proxy Support — Single proxy or rotating proxy file
• Smart Resume — Skip already-validated keys on restart
• Multiple Exports — .txt, .csv, .json output formats
• Self-Update — Built-in kunji update command

Adding a Provider

All providers are defined in pkg/validators/providers/llm.yaml or common-services.yaml — no Go code required.

- name: myprovider
  key_prefixes: ["mp-"]
  key_patterns: ["^mp-[a-zA-Z0-9]{32}$"]
  validation:
    method: POST
    url: "https://api.myprovider.com/v1/chat/completions"
    auth: "bearer"
    body: '{"model":"gpt-4o","messages":[{"role":"user","content":"Hi"}],"max_tokens":1}'
