What is Greip?
Greip is a fraud prevention API platform that gives developers and businesses real-time tools to detect fraudulent payments, fake accounts, suspicious IPs, and invalid user data. It delivers a suite of services through a single API, covering payment fraud analysis, IP intelligence, identity verification, and content moderation. It targets developers, SaaS businesses, e-commerce platforms, and enterprises that need to embed fraud detection directly into their products and workflows.
Features & Benefits
- Payment fraud analysis – Combine BIN checks with AI-driven transaction analysis to identify high-risk and fraudulent payments in real time.
- Card issuer verification – Verify card issuer details including bank name, card brand, and country of issue to enhance transaction security.
- IBAN verification and insights – Validate IBANs and retrieve issuing country and bank information for payment processing workflows.
- Proxy and VPN detection – Identify masked IP addresses using VPNs or proxies to reduce risk from unauthorized or anonymized access attempts.
- IP location intelligence – Retrieve detailed geolocation and device data from any IP address for fraud detection and web personalization.
- Network intelligence (ASN) – Look up autonomous system numbers to understand network ownership and routing for security analysis.
- Country intelligence – Access detailed country-level data to support compliance checks and region-based fraud detection rules.
- User data scoring and validation – Verify and score email addresses and phone numbers to detect fake, temporary, or invalid accounts at registration.
- Content moderation – Detect offensive and profane language in user-generated text to maintain safe platform interactions.
- Custom rules and blacklists – Define unlimited custom rules and blacklists to tailor fraud prevention logic to specific business requirements.
- Real-time dashboard – Monitor suspicious IP events, fake sign-up attempts, fraudulent payment events, and API usage metrics from a centralized dashboard.
- SDKs and libraries – Integrate via official libraries for PHP, Node.js, Python, JavaScript, Go, Ruby, Flutter, and CLI.
- Webhooks and integrations – Connect Greip to external tools and workflows via webhooks and third-party integrations including Zapier and IFTTT.
Real-World Applications
E-commerce platforms and payment processors can use Greip’s fraud prevention API to screen transactions before they complete. The payment fraud analysis layer combines card BIN data with AI risk scoring to flag suspicious activity in real time — reducing chargebacks without adding friction to legitimate customer purchases.
SaaS and app developers dealing with fake account registrations can use the user data scoring and VPN detection features to filter out invalid sign-ups at the point of entry. An email or phone number that scores as temporary or disposable, combined with a masked IP, can trigger a block or additional verification step before an account is created.
Platforms that operate across multiple geographies can use IP location intelligence and country data to enforce access restrictions, apply region-specific compliance rules, or personalize content based on a user’s verified location — independently of self-reported user data.
Development teams integrating fraud prevention into existing products can use Greip’s SDKs and REST API to embed detection logic directly into their codebase. The availability of libraries across major languages, combined with webhook support and Zapier compatibility, makes it practical to connect Greip’s fraud prevention signals to CRMs, alerting tools, and internal dashboards without building custom middleware.
