| Tool | Tier | What it does |
|---|---|---|
token_safety | paid $0.02 | Multi-chain token honeypot/rug check — aggregates GoPlus + honeypot.is into a 0-100 risk score with explainable reasons. |
decode_signature | paid $0.01 | "What am I signing" — decode EIP-712 / Permit / Permit2 / Seaport typed-data into plain English + risk flags (unlimited approval, malicious spender, expiry, NFT-drain). |
approvals | paid $0.01 | Wallet approval-risk scan ranked by exposure + address-poisoning "revoke bait" detection + the revoke calldata you execute yourself. |
simulate | paid $0.02 | Keyless pre-sign transaction analysis: eth_call revert check + static delta prediction + risk flags. |
token_safety_free · decode_signature_free · approvals_free · simulate_free | free | Real teaser results, no wallet. |
Chains: ethereum, base, bsc, polygon, arbitrum, optimism (honeypot.is signals on ethereum/base/bsc).
Paid tools use x402 (USDC on Base, eip155:8453). Call a paid tool with no
x_payment to receive the decoded 402 challenge (price, network, asset, payTo);
build an x402 authorization and call again with the token in x_payment. Humans
can instead prepay by card and use an X-FabTally-Key credit header on the HTTP API.
