An LLM checks every risky action against your rules. Safe actions pass instantly. Dangerous ones need your approval. Your secrets never leave the vault.
How it works
One API call before risky actions. Works with any LLM, any framework, any language.
Your rules are checked against the action by a tiered AI evaluator. Safe actions pass instantly.
Risky actions notify you via email, Telegram, or WhatsApp. Tap to approve or deny.
Encrypted vault
Store API keys in Halcheck's encrypted vault. When your agent needs to call Stripe, OpenAI, or any API — Halcheck injects the secret, makes the call, and returns the response. The agent never touches the key.
result = hc.proxy( secret="stripe-key", url="https://api.stripe.com/v1/charges", description="Charge $29.97" ) # Agent never sees sk_live_... # Halcheck checks, injects, forwards
