Common questions

Is Limitguard Lead Verification safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.11.9) reached the registry 23 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Limitguard MCP Server

Check Dutch and Belgian companies, sales leads and crypto wallets before you deal with them, over the Model Context Protocol: the KVK (Netherlands) and KBO (Belgium) registers, EU VAT (VIES), the OFAC, EU and UN sanctions lists and wallet risk on Base and Solana, with the source and date of every answer.

Server URL: https://api.limitguard.ai/mcp Transport: Streamable HTTP (POST) Auth: API key (Bearer), plus an x402 micropayment per call on the free and sandbox tiers

What it is: 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.

Start here: On MCP a paid tool takes an x402 payment per call, or debits prepaid credit (a paid key, or a funded workspace); wallet_sanctions_preview, sanctions_preview and get_trust_score are free; the free sandbox key returns mock data on the REST API only, not on MCP. Paid by x402: Lead Verify $0.10 per lead and agent check $0.005 per wallet; entity check and KYB $0.29 and risk score $0.25 fresh, $0.11 cached ($0.25 KYB) when available; report $0.55; sanctions and wallet screens $0.005; other routes at the account price. API keys, the dashboard and the Claude connector pay the account prices: 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.

Features

Lead verify for Dutch and Belgian sales leads: is it a real, active company? A verdict, a 0-100 lead score and one action per flag ($0.27 with an API key, $0.10 with x402).
Company check against the KVK and KBO registers, EU VAT (VIES), the domain and the IBAN, with a 0-100 score and a recommendation.
Sanctions screen of company and person names against the OFAC, EU and UN lists, with a free yes/no preview.
Crypto wallet screen on Base and Solana: OFAC address match, balances, wallet age, recent activity and risk rules with advice ($0.11 with an API key, $0.005 with x402).
Free wallet sanctions check: a yes/no against the OFAC list.
AI agent wallet check before your agent pays: sanctions, balance, ERC-8004 identity and public reputation ($0.75 with an API key, $0.005 with x402).
Pay per call in USDC on Base or Solana with x402, or with an API key and prepaid credit. A check that fails is not charged.
MCP, REST and A2A, and agents can pay inside A2A with x402.
Sources on every answer, with the date each one was read. Hosted in the EU.

Tools

tools/list is public: connect and read it without any credential. These are the names it returns, and the names tools/call accepts:

Tool	Description	Inputs
`check_entity`	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.	`entity_name` (required), `country` (required), `kvk_number`, `domain`
`get_trust_score`	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).	`entity_id` (required)
`verify_wallet`	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. Supports EVM and Solana addresses.	`wallet_address` (required), `chain_id`
`get_risk_score`	Quick risk score from sanctions screening and country risk only, without the register or domain lookups of check_entity. 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.	`entity_name` (required), `country` (required)
`get_compliance_report`	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.	`entity_name`, `country`, `kvk_number`, `cbe_number`, `vat_number`, `domain`, `iban`, `wallet_address`, `wallet_chain`, `check_id`
`sanctions_preview`	Free yes/no sanctions preview against the local OFAC SDN, EU and UN lists. Returns possible_match, lists_checked, list_dates and list_note only, never an entry. 10 per caller per UTC day.	`name` (required), `country`
`wallet_sanctions_preview`	Free yes/no check of a wallet address against the OFAC SDN list: sanctioned, lists, the list date and its freshness, no programmes or entry ids. 10 per caller per UTC day, separate from sanctions_preview. The full wallet screen is verify_wallet ($0.11).	`wallet_address` (required), `chain_id`
`sanctions_screen`	Sanctions screen against the local OFAC SDN, EU and UN lists: matched entries with list, entry id, programmes, countries, listing date and match score. A name match is not a determination.	`name` (required), `country`
`check_agent_wallet`	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.	`wallet` (required), `agent_id`, `domain`
`verify_lead`	Verify a NL/BE sales lead against the registers in one call: real and active, VAT, mail server, IBAN, sanctions; a 0-100 lead score. $0.27.	`country` (required), `company_number`, `name`, `vat_number`, `email`, `domain`, `address`, `iban`, `phone`, `target_industries`, `target_size`

Pricing

A paid tool call is debited from your API key's prepaid balance at the account price, or paid per call with an x402 micropayment (USDC on Base or Solana) at the agent price in Agent prices (x402). The tools with their own /v1/mcp/* path are priced below at the account price; the other tools are priced at the REST endpoint they call, in Full x402 API.

Endpoint	Account price
Entity Check (`/v1/mcp/check-entity`)	$1.05
Risk Score (`/v1/mcp/risk-score`)	$0.90
Check Agent (`/v1/mcp/check-agent`)	$0.00: hidden placeholder, not in `tools/list`; returns placeholder data
Trust Score (`/v1/mcp/trust-score`)	$0.00, free (your own stored score)
Verify Wallet (`/v1/mcp/verify-wallet`)	$0.11

Authentication

Two things gate a tools/call, in this order:

An API key, as Authorization: Bearer . Without one every call comes back Authentication required. Provide API key via Authorization: Bearer header. Get a free one (no payment, no card):

   curl -X POST https://api.limitguard.ai/v1/keys/create \

-H "Content-Type: application/json" \ -d '{"email": "you@example.com"}'

That returns a free-tier key, which is the key the Quick Start configs below expect. Asking for "tier": "sandbox" instead returns a key that answers with mock data; see the next point before you use one here.

Payment, on the free and sandbox tiers only. Send the x402 proof as PAYMENT-SIGNATURE (x402 v2) or X-PAYMENT (v1), alongside the Bearer key. A key with a prepaid balance (indie and up) is debited per call instead and needs no per-call payment. API keys have no subscription; see API keys and prepaid balance.

A sandbox key does *not* lift the payment requirement on this transport: it owes x402 per call exactly as a free key does, and it answers with mock data rather than a real check. Paying for one over MCP spends real USDC on a mock answer. Where a sandbox key is worth having is the REST mirrors under /v1/mcp/* (sent as X-API-Key, not Bearer), which serve the mock response before the payment check: a way to exercise the request and response shapes, not a cheap source of real checks.

Agent prices (x402)

An x402 payment pays the agent price: REST, A2A with x402, and MCP pay-per-call on /mcp. An API key, the dashboard and the Claude connector pay the account price, from prepaid credit. A route not listed here costs its account price with x402 too.

The official x402 SDKs refuse a payment above one dollar by default (maxAmountPerPayment). That default covers every agent price. Raise it only for the deep-check enhanced and credit tiers and for the /v1/keys/upgrade/* and /v1/keys/topup/* purchases.

Endpoint	Agent price (x402)	Account price
`POST /v1/entity/check`	$0.29 fresh, $0.11 cached	$1.05 fresh, $0.11 cached
`POST /v1/mcp/check-entity`	$0.29	$1.05
`POST /v1/risk/score`	$0.25 fresh, $0.11 cached	$0.90 fresh, $0.11 cached
`POST /v1/mcp/risk-score`	$0.25	$0.90
`POST /v1/kyb/check`	$0.29 fresh, $0.25 cached	$1.50 fresh, $0.25 cached
`POST /v1/reports/entity`	$0.55	$1.85
`POST /v1/leads/verify`	$0.10	$0.27
`POST /v1/agent/check`	$0.005	$0.75
`POST /v1/mcp/verify-wallet`	$0.005	$0.11
`POST /v1/sanctions/screen`	$0.005	$0.11

Full x402 API (direct HTTP)

The tools above are what the MCP server exposes over the Model Context Protocol. Clients that integrate directly over HTTP, instead of through an MCP client, can reach every x402-priced endpoint on https://api.limitguard.ai: the REST endpoints below, plus the MCP tools' own /v1/mcp/* paths. All of them are published in /.well-known/x402.json; /.well-known/mcp.json lists only the tools above.

Most of the REST endpoints are capabilities the MCP tools do not expose, but two run the same engine over plain HTTP: /v1/entity/check behind check_entity (the MCP tool takes the entity name, country, KVK number and domain only, so no IBAN or VAT), and /v1/risk/score behind get_risk_score, at the same price.

Payment is per call throughout: USDC on Base or Solana, at the agent price in Agent prices (x402). The Price columns below are the account prices an API key pays. The data endpoints below need no API key at all. The /v1/keys/upgrade/* endpoints also take payment without one, but they act on an API key you already hold; see API keys and prepaid balance.
