api.limitguard.ai x402 offerings

EU AI Act readiness self-assessment for one AI system. 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.

Historical reputation trend data. Returns the trust score timeline with the decay applied at each point and an overall trend.

Extended 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.

Reputation 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.

Lead 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.

Preflight before an agent pays an x402 seller: screens the payTo wallet against the OFAC SDN address list, reads who registered the resource domain and when (RDAP), and screens that company against the OFAC, EU and UN lists. Compares the payTo with the wallet the seller publishes in its 402 and /.well-known/x402, and blocks a lookalike (address poisoning). Returns ok, caution or block with one reason per finding.

Light 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.

MCP 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. On Base, also reports any ERC-8004 agent the wallet owns and its open on-chain reputation as descriptive signals, never scored. Accepts EVM (0x...) and Solana (base58) addresses.

Agent 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.
