Bargain / Greip

Bargain / Greip is a developer-oriented API service for payment fraud prevention, founded in 2022 and based in London. The company positions it as a lightweight and inexpensive REST API for basic anti-fraud screening of transactions.

Services The product list includes an AI Payment Fraud API, IP geolocation and proxy detection, BIN and IBAN validation, and email and phone scoring. The service also covers VPN and proxy detection and filtering of abusive or fraudulent registrations.

Who it suits Stated target segments are SaaS, e-commerce, indie and mid-market PSPs and fintech. The coverage is described as global.

Pricing The service uses a freemium model, with paid plans quoted at roughly $15 to $99 per month. Usage limits per plan and any enterprise terms should be checked with the provider before integration.

The listed product set makes it a screening layer that sits in front of payments and sign-ups rather than a full case-management system, so teams usually pair it with their own rules.
