`check_stablecoin_freeze`Check whether Tether (USDT) or Circle (USDC) have blacklisted a wallet address on-chain. Reads the issuer's blacklist function directly across 15 chains (ETH, BSC, POLYGON, ARBITRUM, OPTIMISM, BASE, AVALANCHE, PLASMA, HYPEREVM, STABLE, INK, BERACHAIN, ROBINHOOD, TRON, SOL). A frozen address can no longer send or receive that stablecoin. Also reports whether the address was PREVIOUSLY frozen and later unfrozen (a prior-freeze signal from the freeze ledger). The result reports the observed on-chain fact (frozen / not frozen at check time), never the cause of a freeze. Free.

`check_token_approvals`List a wallet's active ERC-20 token approvals on Ethereum and who can move its funds — risk-scored against BA's 1B+ entity labels (scam / phishing / exploit / sanctioned spenders), flagging unlimited allowances and stale grants. The wallet's attack surface at a glance. Read-only. Ethereum only. Free.

`check_token_security`Simulate a buy-and-sell of an ERC-20 token on its main DEXes to surface honeypots (tokens you can buy but not sell), extreme transfer taxes, name/symbol impersonation, and active mint authority — cross-referenced against BA's 1B+ entity labels. Reports observed facts (e.g. 'sell simulation reverted'), not verdicts. Live on Base, BNB Chain, Ethereum, Optimism, Polygon, Arbitrum. No transaction is sent. Free.

`get_freeze_events`Query the canonical stablecoin freeze ledger — the HISTORY of freeze / unfreeze / destroy events by Tether (USDT), Circle (USDC/EURC), Paxos (USDP) and First Digital (FDUSD), sourced from the issuers' own on-chain blacklist events across Ethereum, Polygon, Optimism, TRON and more. Filter by frozen address, chain, kind, or time; omit all filters for the most recent events. This is the EVENT HISTORY — to check whether an address is frozen right now, use check_stablecoin_freeze instead. Each row is a verifiable on-chain fact (issuer acted on address at block/time); it never states the cause. Free.

`kyt_risk`Assess a wallet's KYT (Know-Your-Transaction) risk: sanctions + entity classification + VASP/jurisdiction score + cluster context → one risk verdict (critical / high / medium / low / unknown) with flags.

`kyt_tx`Transaction KYT: screens BOTH counterparties of a transfer (from → to) against sanctions + entity + VASP + cluster, returning a combined risk level, a block/review/allow recommendation, and directional FROM:/TO: flags.

`label`Look up BlockchainAnalysis's entity labels for a single address: every label on record (sanctions from OFAC / EU / UN / UK HMT / Swiss SECO, issuer-freeze state, scam, phishing, exploit, mixer, exchange, and more), each with its category, threat level (SAFE to CRITICAL), and full provenance (source, source URL, confidence, and the date it was last verified). Each accusation (scam, phishing, mixer...) carries evidence.verified; one that states no verifiable evidence is listed last. This is the raw label read behind BA Intel, the only way to buy it per call with no account and no API key. An address we hold no label for returns an explicit not-found with the reason, never an empty result, and an absent label is not a statement that the address is safe.

`oracle_verdict`Consumer-protection verdict for a wallet or contract: a normalized verdict (safe / warning / danger, or unknown) with a 0-100 score, confidence tier, and plain-language reasons.

`rwa`Identify a tokenized real-world asset from its token address: what it represents, who issues it, its asset class, ISIN and issuer jurisdiction, whether transfers are permissioned, and every chain the issuer publishes it on. Each answer carries its provenance: the issuer source, how the address was established (issuer-registry / issuer-page-only / third-party), a confidence, and the date the address was last round-tripped on-chain. An address we do not recognise returns an explicit not-found with the reason, never an empty result. Does NOT cover the issuer's control over a balance (pause, blocklist, seizure).

Exchanges and other service labels do not flag a wallet, and neither does an accusation that states no verifiable evidence (counted in unverified_count). Deliberately a verdict only — the label detail, freeze history, and scores are in the paid screen_address / kyt_risk tools, and a signed, on-chain-anchored proof is in the paid screen_agent_wallet_attested tool.
