Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_token_safety | Honeypot / contract safety check for any ERC-20 token. | Read-only |
| evaluate_trade | Pre-trade risk check for a proposed trade. Call this BEFORE executing any trade and treat a "deny" decision as a hard stop. Evaluated at a fixed Tier 1 ceiling ($5,000 notional). For higher limits, use `evaluate_trade_paid` (Tier 2, $25,000) which settles an x402 payment on-chain. | Read-only |
| evaluate_trade_paid | Pre-trade risk check gated by an x402 payment. Evaluated as COLR Tier 2: $25,000 notional ceiling, 10/25 per-minute rate limits. No COLR holdings are required — the on-chain payment is the credential. FLOW ---- 1. Call WITHOUT payment_proof → the tool returns a `PaymentRequiredOutput` describing the on-chain payment (network, asset, amount, payTo, resource). 2. Settle the payment on-chain using an x402-capable client. The facilitator returns a proof string. 3. Call again with `payment_proof=<proof>` → the tool forwards the proof to the guardrail's x402-paid endpoint and returns a full `EvaluateTradeOutput` with `tier=2`. | Read-only |
| get_supported_assets | List every asset in the guardrail's official Robinhood Chain registry, with its canonical contract address. | Read-only |
| simulate_balance | Simulate a wallet's ERC-20 balance after a hypothetical trade using eth_call state override. Read-only: no transaction is ever sent. | Read-only |
| verify_audit_trail | Verify the tamper-evident audit trail for a wallet's past guardrail decisions. | Read-only |
