Callable
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.
