API Integration & Implementation
LLM APIs, MCP servers and system integration done right
Start a projectIn short
A demo integration takes a weekend. A production one has to handle rate limits, cost spikes, prompt injection, PII and the model changing underneath you. We do the second kind: LLM APIs and MCP servers wired into your stack with the boring, load-bearing parts done properly.
Deliverables
What you get.
Everything listed here is a thing you can hold: a document, a system, a working piece of software. Not hours, not effort.
- 01LLM API implementation (Claude, GPT, Gemini) behind an abstraction layer, so the model stays swappable
- 02Custom MCP servers that expose your tools and data to models safely and auditably
- 03Cost engineering: caching, prompt design, model routing and budget alerts
- 04Security review of every data path, including PII handling and injection defenses
- 05End-to-end pipelines from your data to the feature your users touch
- 06Documentation your own developers can extend without us
Capabilities
What we can take on.
The concrete jobs this service covers. Yours is not listed? Ask anyway: the honest answer is often a sibling service.
- Payment gateways and billing systems
- CRM, ERP and accounting connections
- Shipping, logistics and inventory APIs
- Sign-in with Google, Microsoft and other identity providers
- Webhooks and event pipelines between your tools
- Data sync between systems that were never designed to talk
Process
How we work.
Four stages, one line. The order never changes; the depth does.
- 01Map the data pathWhat goes into the model, what comes out, and what must never leave your systems.
- 02Prototype the riskiest call firstIf the core interaction does not hold up, we find out early, not at month three.
- 03HardenRate limits, retries, injection defenses, cost caps and logging go in before launch.
- 04Hand over with docsYour team gets the keys and the knowledge, not a dependency on us.
The working model
The harness, drawn.
Four stages, narrated, with captions. Sound is off until you ask for it.
Why Web Fortuners
Three reasons, checkable.
- 01
We build on these APIs for our own client work
The integration patterns are tested in production, not read from a tutorial.
- 02
Cost is engineered, not hoped for
You get cost-per-action visibility from the first week.
- 03
Integration is one of four pillars in the same studio
The API work and the product it powers are designed together, not handed off between vendors.
FAQ
Questions, answered.
The things people ask before they write to us. Yours is not here? Ask it directly.
It depends on the task, and the honest answer changes every few months. We implement against an abstraction layer so the model is swappable, then benchmark Claude, GPT and Gemini on your workload and wire in the winner.
MCP is a standard way to expose your tools and data to a model safely. If you want an assistant or agent to act inside your systems, an MCP server is usually the cleanest and most auditable way to allow it.
Caching, prompt discipline, routing small tasks to small models, and budget alerts wired into the build. You see cost per action in the logs, not a surprise invoice at the end of the month.
Fixed scope per integration, quoted in writing before work begins. Ongoing API usage is billed to you directly by the provider, with no markup from us.
