Limitguard
■ Challenge detectedAgent wallet check in one call: screens an EVM wallet against the OFAC SDN digital-currency address list, reads its Base USDC and ETH balance, looks up its ERC-8004 identity registration (and, given an agent id, that agent's owner and payment wallet) and lists open ERC-8004 feedback, which is not scored. Returns one verdict and each part's status; a part that could not be read says so.

Base URLhttps:
- POST/seller

Returns one verdict and each part's status; a part that could not be read says so. - POST/mcp
/verify-wallet$0.005MCP tool: 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.

/history /:entity_hash$0.11Historical reputation trend data. Returns the trust score timeline with the decay applied at each point and an overall trend. - POST/entity
/light-check$0.05Light company check for an agent: is the company on the NL (KVK) or BE (KBO) register and active, is its EU VAT number valid (VIES), and does its name match the OFAC, EU or UN sanctions lists? Each part says ok, not covered or unavailable. No owners, PEP or address match. - GET/wallet

/screen$0.005Sanctions screen of a company or person name against the OFAC SDN, EU and UN sanctions lists, held locally and refreshed daily. Returns each matched entry: list, entry id, matched name, programmes, countries, listing date and match score. Exact normalised or word-order-insensitive name match only; a name match is not a determination. - POST/risk
/score$0.25Quick risk score (0-100) for entity name + country. Lightweight check without full data source scan. - POST/entity
/deep-check$0.88Extended screening in two tiers. fresh ($0.88): politically exposed person and relative/close-associate (role.pep / role.rca) matches from OpenSanctions, with the match detail the standard entity check does not return, plus a Dutch Centraal Insolventieregister screen (NL only). enhanced ($1.71): the same plus adverse media screening against a global news index. If a source of the requested tier cannot be reached the call returns 503 and is not charged. - POST/mcp
/check-entity$0.29MCP tool: entity trust check for LLM agents. Runs the /v1/entity/check engine on entity_name, country, kvk_number and domain only, so up to 5 sources (no IBAN, VAT or wallet). - POST/reputation
/score$0.9Reputation scoring with linear trust decay: after its first week a score loses 2-5 points a week by risk cluster (none for a sanctions-flagged entity), plus a bonus of up to 5 points for repeat verifications. - POST/entity
/check$0.29Full entity trust check across multiple verification layers: KVK/CBE registry, OpenSanctions, country risk (CPI/FATF), domain WHOIS, IBAN validation and EU VAT/VIES. Returns trust score 0-100 with cluster and recommendation. - POST/leads
/verify$0.1Lead verify for one NL or BE sales lead: is it a real, active company? Checks the KVK or KBO register and cross-checks what the lead holds: VAT with VIES, mail server and disposable domain, IBAN country and bank (not the holder), and the company name against the OFAC, EU and UN sanctions lists. Returns a verdict, a 0-100 lead score and flags, each with one action. An input not given is not checked. - GET/compliance
/alerts$0.11Daily changes to the OFAC, EU and UN sanctions lists, plus alerts when an entity or wallet this key checked is listed. Poll this route; alerts about entities or wallets this key checked are also sent to a webhook registered for sanctions.match.new (POST /v1/webhooks). Filter by jurisdiction and severity. - POST/reports
/entity$0.55Per-entity report built from one real check's signals: identity, sanctions and PEP screening, domain signals, trust score (risk.trust_score, 0-100, 100 = best), correlations with the caller's earlier reports, sources and an evidence hash. A source that did not answer is shown unavailable, never clean. - GET/compliance

Send the system_type and the checklist items you have completed (completed_items); returns the EU AI Act risk level for that system type, a readiness score and the open gaps. entity_id is your label: nothing is looked up about it.
