🔩 8-What Makes Our API Layer Lending-Grade
How we built a secure, auditable, integration-first system for modern credit infrastructure.
✍️ Written from Riyadh — for founders, product teams, and AI builders in regulated markets.

Lenders don’t operate in silos. They pull data from bureaus, run decisions through scorecards, store results in CRMs, and trigger actions in core banking systems. And yet — most AI or credit scoring vendors treat integration like a footnote. They ship a model and say: “Your engineers will figure it out.”
That’s not how we work.
We built Qararak’s API layer to be first-class infrastructure — just like our model engine or decision logic. Because credit platforms don’t win on UX alone. They win on interoperability.
🔧 1. Built from Day One as API-First
From scoring to decision logs, everything in Qararak is exposed via RESTful APIs — with structured, versioned, and schema-validated endpoints.
Whether you’re integrating borrower intake, document pipelines, rule updates, or score queries — every action is available via API.
Stateless, JSON-based interfaces
Clean payloads designed for dev teams
Webhook-compatible for external triggers
Documented via Swagger/OpenAPI
We built this for developers who don’t want surprises.
🔐 2. Security That Meets Financial Standards
We’re not a consumer app.
So our security model matches what serious lenders expect:
JWT-based authentication
API key rotation + scoped permissions
Rate limiting and IP whitelisting
TLS 1.3 enforced across all endpoints
Role-based access mapping to client-side SSO or Active Directory
This isn’t “good enough security.” It’s bank-grade architecture.
📊 3. Auditable by Design
In lending, every API call might be questioned — by your compliance team, or by a regulator 9 months later.
So we log everything.
Who called which API
With what payload
What version of the rule/model was triggered
What the response was, and why
This creates a traceable decision fabric, not just a system that “works today.”
🔄 4. Plug-and-Play with Core Lending Systems
We’ve integrated with the full stack of lending ops:
Credit bureaus (Simah, Bayan, Nafath)
Core banking & LOS
CRM & ticketing tools
Document capture & OCR platforms
Client-specific frontends via embedded APIs
You don’t need to rebuild your stack.
Qararak becomes the intelligence layer that slots into what you already have.
🧠 5. Designed for Real-Time Use Cases
Unlike batch-oriented risk engines, Qararak’s API layer is real-time and low-latency by default.
Use cases it supports:
Real-time loan pre-approvals
Automated pricing lookups
API-triggered document validation
Embedding Qararak models into mobile/web flows
Instant explanation retrieval for declined applications
We support request-response cycles under 200ms (in GPU-backed on-prem setups).
Because speed isn’t a luxury — it’s how credit gets disbursed.
🧭 Final Word
An AI model is only as useful as the ecosystem it connects to.
Qararak’s API layer was built not as an afterthought — but as core infrastructure.
It’s what lets clients trust us, extend us, and deploy us without months of friction.
If you’re building or modernizing a credit product, ask every vendor:
“What does your API actually let us do
With us, the answer is: everything.
Securely, scalably, and visibly.
