An Integration That Works Until It Does Not
APIs time out, hit rate limits or change. Without proper handling, your feature fails in front of customers.

IN PLAIN ENGLISH
What Is AI API Integration – and What We Do Differently
AI API integration means calling AI services such as OpenAI, Claude or Gemini from your own software. Getting a first response is quick. We focus on what happens on a busy day: retries, timeouts, rate limits, cost caps, logging and fallbacks to another provider if one goes down.
SOUND FAMILIAR?
Business Problems Our AI API Integration Solves
API Keys Stored Unsafely
Keys in front-end code or shared documents are a real risk. We store and rotate them securely.
No Plan If a Provider Has an Outage
If your only AI provider goes down, so does your feature. We add fallbacks to a second provider.
Costs That Are Hard to Track
Without usage tracking, you cannot see which features or customers drive cost. We tag and report every call.

AI Opportunity Audit
We review your software, its APIs, your data and the jobs where AI would help most inside the tools people already use.
Roadmap & ROI Forecast

Build & Integrate
We build the connection, the prompts and any new screens, and add logging so every AI request can be traced.
Test, Train Your Team & Launch
We test with real data in a safe environment, train your team and roll out to a small group before everyone.
Monitor, Optimise & Scale
We monitor usage, cost and errors, update to better models when they arrive and add integrations as you need them.
