Merchant Check Pro

A dated web-presence report for every merchant you onboard.

For payment facilitators, PSPs and marketplaces that must look at a merchant's website before onboarding and keep checking it afterwards, and need a record of what they saw and when.

What you get

One call returns a merchant report: domain age and registrar, HTTPS certificate, email authentication (MX, SPF, DMARC), presence of returns policy and contact details, public phishing-list check, popularity rank, and an indicative risk level with the reasons.

Optional: screen the merchant's legal name against official sanctions lists (OFAC, UN, EU, UK) and search official product-recall notices for its brand, in the same report.

Every report is timestamped, stored for 400 days, and carries a SHA-256 fingerprint so you can show later exactly what was checked and when.

Watchlist: add merchants and we re-check them every week, recording what changed (new red flag, certificate expired, site down, new sanctions result). Changes are available by API and can be pushed to your webhook.

How it works

Choose a plan and pay by card or PayPal (monthly, cancel anytime).
Get your API key right away. Card payments land directly on your key. With PayPal, enter your subscription ID on the key page.
Call the API with your key. Every answer shows how much of your monthly quota is left.

Data sources

The merchant's homepage is read only when its robots.txt allows it.

What it is not

It is not a certification, an accreditation or an approval by any card network or regulator, and it does not make onboarding decisions for you.
Signals are rule-based and indicative: an unknown is not a bad sign, and a flag needs a human look. You remain responsible for your own risk and compliance programme.
No uptime commitment (SLA) in these plans.
