🟢token_safety(address, chain, x_payment)

PAID $0.02 (x402, USDC on Base). Multi-chain token honeypot/rug check aggregating GoPlus token-security + honeypot.is buy/sell-tax simulation into a normalized 0-100 risk score with explainable reasons: honeypot/can't-sell, buy/sell tax, mint/blacklist/pausable/ownership privileges, top-holder concentration, LP-lock, contract verified/bytecode. Descriptive facts only — NOT a buy/sell signal. Without payment returns the x402 challenge; pass x_payment to settle. Free teaser: token_safety_free.

⚪token_safety_free(address, chain)

FREE. Score band + top-line honeypot/tax/privilege flags for a token {address, chain}. Real result, no wallet. Upgrade to token_safety for the full numeric breakdown.

⚪decode_signature(typed_data, chain, x_payment)

PAID $0.01 (x402, USDC on Base). Decode an off-chain EIP-712 typed-data signature (Permit / Permit2 / Seaport / generic) into plain English with risk flags: unlimited approval, unknown/known-malicious spender, never-expiring or already-expired deadlines, zero-consideration NFT-drain orders. Off-chain signatures are the top wallet-drainer vector. Pure offline decode — never signs/broadcasts. Without payment returns the x402 challenge; pass x_payment. Free teaser: decode_signature_free.

FREE. Type + plain-English summary + risk level for an EIP-712 `typed_data`. Real result, no wallet. Upgrade to decode_signature for the full field-by-field decode + all risk flags + malicious-spender screening.

⚪approvals(address, chain, x_payment)

PAID $0.01 (x402, USDC on Base). Scan a wallet's ERC-20/721 approvals ranked by exposure; flags unlimited amounts, unverified/known-malicious spenders, and address-poisoning 'fake-approval revoke bait'; returns the exact revoke calldata you execute YOURSELF (never executed/broadcast by us). Without payment returns the x402 challenge; pass x_payment. Free teaser: approvals_free.

🟢simulate(chain, from, to, data, value, ...)

PAID $0.02 (x402, USDC on Base). Keyless pre-sign analysis of {chain, from?, to, data, value?}: public-RPC eth_call revert check + static calldata decode predicting approval/transfer deltas + risk flags (unlimited approval, approval-for-all, reverts). Honest keyless limitation stated in the response (no full fork trace). Without payment returns the x402 challenge; pass x_payment. Free teaser: simulate_free.
