🟢check_entity(entity_name, country, kvk_number, domain)
Company check via the Limitguard API. Company check on a business: sanctions screening and country risk, the Dutch KVK register for an NL company, and the website domain when you send it. Returns trust_score (0-100, 100 = best), trust_level (high means low risk), cluster, recommendation, confidence, top_factors and sources_checked. Args: entity_name: Full legal name of the entity country: ISO 3166-1 alpha-2 country code (e.g., NL, BE, DE) kvk_number: Optional Dutch KVK registration number (8 digits) domain: Optional company website domain

}🟢get_trust_score(entity_id)
Look up your own most recent trust score for an entity you checked before, from your stored checks: score, level, when, which product, trend and how many checks are on record. Runs no new check and calls no data source. Free ($0). Returns status "found" with trust_score, trust_level, checked_at, source_product, trend and checks_on_record, or status "not_found" with a next_step. Only checks made with your key (via check_entity, or REST entity/KYB checks) are read; another key's or workspace's never are (#946). Signed in with OAuth, your workspace's checks are read instead (#1062). Args: entity_id: The entity name, as you sent it to check_entity

}🟢verify_wallet(wallet_address, chain_id)
Screen a wallet: OFAC SDN address match, on-chain signals (contract check, native and USDC balance, transaction count, first seen on Base) and named risk rules with up to 3 advice items. On Base, also reports any ERC-8004 agent the wallet owns and its open on-chain reputation as descriptive signals, never scored. $0.11. Returns risk_score, risk_level, sanctions (hit, lists, as_of), signals with their source, the names of signals that could not be read (unavailable), rules_fired, advice and linked_entities (entities you checked that were linked to this wallet). On Base, also erc8004_agent_ids and erc8004_reputation (open ERC-8004 feedback, descriptive only -- never folded into risk_score or advice). Accepts EVM (0x...) and Solana (base58) addresses. The sanctions match alone is free: the wallet_sanctions_preview tool. Rejected calls are not charged. Args: wallet_address: Blockchain wallet address chain_id: CAIP-2 chain ID (default: eip155:8453 for Base); base, eth, solana, btc also accepted

}🟢get_risk_score(entity_name, country)
Quick risk score from sanctions screening and country risk only. Faster than check_entity: no register or domain lookup. Use when you only need basic risk evaluation. Returns risk_score (0-100, 100 = riskiest), risk_level (high means high risk, the reverse of check_entity's trust_level), sanctions_match and fatf_status; no recommendation or factors. Args: entity_name: Full legal name of the entity country: ISO 3166-1 alpha-2 country code

Per-entity report built from one real check. Registry identity, sanctions and PEP screens, domain signals, risk score with the rules that fired, correlations, every finding as a ranked action, a per-source status table (ok / unavailable / error) and a report hash. Args: entity_name: Full legal name (with country; omit when sending check_id) country: ISO 3166-1 alpha-2 country code kvk_number: Optional Dutch KVK number (8 digits) cbe_number: Optional Belgian CBE number (0XXX.XXX.XXX or 10 digits) vat_number: Optional EU VAT number domain: Optional company website domain iban: Optional IBAN (never stored raw) wallet_address: Optional crypto wallet address (format check only) wallet_chain: Optional chain for wallet_address (eth, base, btc, sol, ...) check_id: Id of a check from an earlier report, instead of identifiers

Check a counterparty agent's EVM wallet in one call: OFAC SDN digital-currency address list match, Base USDC and ETH balance, ERC-8004 identity registration (and, given an agent id, that agent's owner and payment wallet) and open ERC-8004 feedback, which is not scored. $0.75.
