All-in-one backend for SaaS products.

A product by Bobadilla Technologies

Requiems API

Authentication, validation, fraud detection, payments intelligence, and global data behind one API key.

Stop rebuilding the same backend plumbing for every SaaS product.

Systems

Four systems, each built around a problem SaaS teams actually hit.

• Identity & Risk - keep fake users, fraud, and bad data out before they reach your database.
• Payments Intelligence - validate and enrich financial data to cut failed payments and catch risky transactions.
• Global Data - accurate, real-time location and compliance data for international products.
• Data Integrity - clean, validate, and standardize user input across your platform.

Engines

Need a decision, not just raw data? Compose an engine.

POST /v1/signup/protect
{
  "email": "user@tempmail.io",
  "ip_address": "45.33.32.156",
  "phone": "+14155552671"
}

{
  "risk_score": 0.87,
  "is_safe": false,
  "confidence": 0.94,
  "flags": ["disposable_email", "vpn_detected"],
  "signals": {
    "email_valid": true,
    "phone_valid": false,
    "vpn_detected": true,
    "disposable_email": true
  }
}

Each engine fans out across validation, networking, and intelligence APIs in parallel, then hands back one structured result.

Where It Fits

• Signup protection - block fake accounts, bots, and abusive signups.
• Fintech onboarding - validate financial data and cut onboarding friction.
• Marketplace fraud prevention - catch risky users and transactions as they happen.
