Tools 14 found in our last check

• check_logic

  Catch contradictions in reasoning before acting on it. FREE — no account needed. Extracts quantitative and logical claims from any plan, calculation, or chain of thought, then uses a Z3 SAT solver to mathematically prove whether they contradict each other. This is formal verific…

• check_relevance

  Free relevance screen — checks whether an action touches any of your policy variables before running a paid check. Returns a relevance score and which variables matched. If should_check is true, run check_action. If false, the action is unrelated to your policy — skip the paid c…

• make_rules

  Turn a plain-English policy into a jailbreak-proof guardrail. Write rules the way you would explain them to a colleague — ICME compiles them into formal logic (SMT-LIB) that a mathematical solver enforces. No prompt engineering. No LLM judges. The solver either proves an action…

• check_action

  Enforce a guardrail: verify an agent action against a compiled policy using formal verification. An SMT solver — not an LLM — determines whether the action satisfies every rule. Returns SAT (allowed) or UNSAT (blocked) with extracted values and a cryptographic ZK proof that the…

• check_action_paid

  Same formal verification as check_action, but pay per call with x402 ($0.10 USDC on Base) instead of using credits. No API key or account needed — any agent with a wallet can verify actions on the fly. Returns SAT (allowed) or UNSAT (blocked) with extracted values and optional Z…

• quick_check

  Fast yes/no guardrail verdict — returns only ALLOWED or BLOCKED with no proof details. Use when you need a lightweight gate and don't need the full SAT/UNSAT report or ZK proof. Same formal verification under the hood, just a minimal response. 1 credit. Requires api_key.

• verify_proof

  Independently verify a ZK proof from a prior check_action call. Confirms the guardrail check was performed correctly without re-running it — any third party or monitoring agent can verify in under one second. No additional cost. Wait a few minutes after the check for the proof t…

• get_scenarios

  Review auto-generated test scenarios for a compiled policy. Shows example actions that should pass and fail, so you can verify the policy behaves as intended before deploying it. Requires api_key.

• run_tests

  Run saved test cases against a policy to confirm it blocks what it should block and allows what it should allow. Run this after make_rules and before using the policy in production. Requires api_key.

• create_account

  Create an ICME Preflight account with x402 USDC payment ($5.00 on Base). Returns an API key and 325 starting credits immediately. Save the api_key — it is shown only once. Use create_account_card instead if paying by credit card.

• create_account_card

  Create an ICME Preflight account with a credit card ($5.00 via Stripe). Returns a checkout_url — open it in a browser to pay. After payment completes, call poll_session with the session_id to retrieve your API key.

• top_up

  Add 500 credits to your account via x402 USDC payment ($5.00 on Base). Use top_up_card instead for credit card payment with volume discounts. Requires api_key.

• top_up_card

  Add credits via credit card with volume bonuses. Returns a checkout_url. Tiers: $5 = 500 credits, $10 = 1,050 (+5%), $25 = 2,750 (+10%), $50 = 5,750 (+15%), $100 = 12,000 (+20%). Credits never expire. Requires api_key.

• poll_session

  Check the status of a Stripe card payment. Returns pending or complete. On completion after signup, returns the api_key. Call this after create_account_card or top_up_card once the user has paid.
