Tool Tokens

check_token_safety ~139

Risk-check an ERC-20 before trading it: metadata, contract + ownership status, upgradeable-proxy detection, holder concentration, and a transfer/honeypot simulation → risk signals + a score. The deep checks (concentration, honeypot) are heavy: needs NODEFLARE_API_KEY or X402_PRIVATE_KEY. Works on young chains (Zircuit, Robinhood, Plasma, Ink) that big indexers leave empty.

Input Output Examples

Name	Type	Req	Description
chain	string	yes	Chain — slug (eth, base, robinhood…), name, or chain ID
token	string	yes	0x ERC-20 contract address to check

No output schema declared.

No examples provided.

compare_gas ~80

Compare current gas price ACROSS chains in one call — gwei per chain, cheapest first, so an agent can pick where to transact. Defaults to the majors (eth, base, arb, op, bnb, polygon); pass chains to override.

get_multichain_balances ~330

chains	array	—	Chains to include — slug, name, or chain ID; defaults to all 23
discover	boolean	—	Auto-discover the ERC-20 tokens the address holds via Transfer logs. Needs an x402 wallet (heavy method). Comprehensive on young chains; large chains cap the scan — narrow with fromBlock.
fromBlock	string	—	Start block for discovery (hex or 'earliest'); narrow the window on high-history chains
includeDust	boolean	—	Discovery only: keep dust balances below 1e-9 units. Default false.
includeSpam	boolean	—	Discovery only: keep tokens with no DefiLlama price (likely spam/airdrops) on price-covered chains. Default false.
minUsd	number	—	Discovery only: drop discovered tokens worth less than this USD value on price-covered chains (default 0.01, filters near-worthless spam). Set 0 to keep any priced token.
tokens	object	—	ERC-20 contract addresses per chain, e.g. { base: ['0x833589…'] }

No output schema declared.

No examples provided.

get_token_allowances ~129

ERC-20 approvals a wallet has granted (what it approved and for how much) across many of the 23 EVM chains in ONE call — including young chains (Robinhood, Plasma, Ink) that revoke.cash-style tools skip. Scans Approval logs, reads the live allowance, drops revoked ones, flags unlimited approvals. Heavy: needs NODEFLARE_API_KEY or X402_PRIVATE_KEY.

Onchain Answer Engine: ask a plain-English question about any wallet or token across the 23 EVM chains and get back a CITED verdict in one call — 'is token 0x… on <chain> a scam?', 'what does wallet 0x… hold?'. NodeFlare plans the on-chain lookups, runs them on its own nodes, and synthesizes a sourced answer. Paid: needs NODEFLARE_API_KEY or X402_PRIVATE_KEY (no free anonymous tier — it runs on a GPU).

Input Output Examples

Name	Type	Req	Description
chain	string	yes	Chain — slug/name/ID
data	string	—	0x calldata (default 0x)
