AI Development & LLM Integration

AI API Development

Production-grade REST and GraphQL APIs that expose your AI models, RAG pipelines, and ML predictions to internal teams and third-party integrators — with authentication, rate limiting, versioning, and full observability.

Overview

What is AI API Development?

Production-grade REST and GraphQL APIs that expose your AI models, RAG pipelines, and ML predictions to internal teams and third-party integrators — with authentication, rate limiting, versioning, and full observability. Our team brings production-grade expertise to every engagement, ensuring your ai api development implementation delivers measurable business outcomes from day one. We architect, build, and maintain solutions that scale with your organisation and satisfy GCC regulatory requirements.

What's included

RESTful and GraphQL AI API design following OpenAPI 3.0 specifications
JWT and API-key authentication with scoped permissions and usage quotas
Rate limiting, request queuing, and circuit breakers for LLM-backed endpoints
Streaming endpoint support with SSE for real-time token delivery
Full observability: per-endpoint latency, error rate, cost, and quality metrics
Versioned API design with backward-compatible evolution and deprecation notices
Key Benefits

Why It Matters

The measurable outcomes our clients achieve with AI API Development.

Shareable AI Capabilities

Package your AI models as clean APIs that internal teams, partners, and third-party products can integrate in hours.

Secure by Design

Authentication, scoped permissions, and rate limiting ensure only authorised callers can invoke your AI endpoints.

Full Production Observability

Per-endpoint dashboards track latency, error rates, token spend, and model quality — so you can optimise proactively.

Scales with Your Traffic

Request queuing and circuit breakers protect LLM backend from traffic spikes without dropping requests.

Delivery Lifecycle

How We Deliver

A structured, transparent process from kick-off to launch and beyond.

1
Discovery1 week

Requirements & API Contract Design

Define all endpoints, request/response schemas, authentication model, and versioning strategy in an OpenAPI spec before development begins.

2
Planning1 week

Architecture & Cost Modelling

Design token budget strategy, caching tiers, rate limiting policy, and multi-tenant isolation model before writing code.

3
Architecture1 week

Backend Scaffolding & LLM Gateway

Set up project with layered architecture, middleware stack, error handling patterns, and LLM provider integration layer.

4
Build2–4 weeks

Feature Development & LLM Wiring

Implement each endpoint with prompt assembly, model calls, streaming handlers, structured output validation, and semantic caching.

5
QA & Security1 week

Auth, Rate Limiting & Security Hardening

Implement JWT/API-key auth, per-key rate limiting, OWASP Top 10 audit, prompt injection tests, and secrets management.

6
Launch & ScaleOngoing

Observability, Load Testing & Go-Live

Deploy Langfuse dashboards, run k6 load tests to 10× peak traffic, validate circuit breaker behaviour, and launch with runbooks.
