Limitguard is a lead validation service for lead generation agencies, B2B marketing and sales teams: it checks the company behind each lead against official business registers (full coverage in the Netherlands and Belgium), EU VAT and sanctions lists, with website age in the company check, and returns proceed, review or block with the source on every line. Developers and AI agents can use its HTTP API, MCP server and A2A service, hosted in the EU. Free sandbox key, no wallet. The sandbox covers entity, risk and KYB checks; Lead Verify and the agent check need a live key or an x402 payment. Lead Verify $0.27 per lead and agent check $0.75 per wallet; $0.11-1.85 per call; entity and risk checks $0.88-1.05 fresh ($1.50 KYB), $0.11 cached ($0.25 KYB) when available. Lead verification for NL and BE leads, plus entity, KYB and agent wallet checks for developers and AI agents.

Capabilities
Declared skills, tags, and input/output modes.
Verification
Evidence state, method, source, and observation time.
Activity
Registration changes and observed relationship counts.
Operations
Latest endpoint and protocol check, timestamp, and freshness.

lead_verify
lead_verify
Lead verify for one NL or BE sales lead: is it a real, active company? Checks the KVK or KBO register (status, legal form, start date, main activity, staff, registered address) and cross-checks whatever else the lead holds: VAT number with VIES, mail server and disposable domain, IBAN country and bank (the account holder is not checked), and the company name against the OFAC, EU and UN sanctions lists. Returns a verdict, a 0-100 lead score, flags and one action per flag. An input not given is not checked and never counts against the lead.

agent_check
agent_check
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.
