OpenAI & Claude API integration: LLM features that behave the same on day 100 as on demo day.

Calling a model is easy. Making it reliable is the work: answers in a shape your code can check, retrieval over your own data, limits so usage can’t run up a surprise bill, and a fallback when a provider is down. The OpenAI API is part of TeckNow and Mebag.

How we use OpenAI & Claude APIs

We add OpenAI or Claude to products regularly, from a Node.js backend.

  1. Daily
  2. Regularly
  3. When it fits

Where it works well

  • Drafting, summarising and sorting text inside your product
  • Search and answers over your own documents and records
  • Turning messy input, like emails and forms, into structured data
  • Assistants that call your own APIs to get things done

Where it breaks down

  • The answer must be exactly right every time with no human check
  • Nobody measures quality, so a model update breaks it silently
  • No usage limits, so one busy customer runs up the bill

What we use instead

  • Plain codeIf rules can do it, rules are cheaper and exact.
  • AI agents For multi-step work across tools.

You’re probably here because…

What people usually need when they search for OpenAI & Claude APIs help.

Your AI feature worked in the demo and wobbles in production.

Structured outputs and checks.

The model returns data your code validates, with a retry or a fallback when it doesn’t fit.

Your API bill keeps growing.

Budgets per user and per feature.

We track usage, cache what repeats and use smaller models where they are good enough.

The model doesn’t know your business.

Retrieval over your data.

Your documents and records searched first, so answers come from what you actually hold.

What we build with OpenAI & Claude APIs

The engineering around the model.

Retrieval over your data

Answers grounded in your own documents and records.

Guardrails and checks

Validated outputs, test sets and human review where it matters.

Cost controls

Per-user budgets, caching and model choice per task.

Provider fallback

Switch between OpenAI and Claude without a rebuild.

How a build runs

The same steps on every project. You approve designs before we write code.

  1. Day 1

    A 30-minute call

    Bring the problem and how you handle it today. We ask questions and tell you honestly what we would build first. We won’t pitch at you.

  2. Next

    Written proposal and fixed quote

    What is in scope, what goes on the backlog, the stack we’d use and why, the timeline and one price.

  3. Week 1

    Onboarding

    A kick-off meeting, a shared Slack channel and access to the repository. Rehan is your day-to-day contact.

  4. Design

    Designs you approve

    We design the main screens and journeys first. Nothing gets coded until you have signed the designs off.

  5. Build

    Architecture first, then code

    We agree the architecture before writing code, then build with updates twice a week on Slack. Any new request is logged as extra hours and reported weekly.

  6. Launch

    Live, handed over, supported

    Deployed to production with your Git repositories and documentation handed over. Bug fixes are free for the first two months.

What it costs

It depends on scope, so we do not publish a price list. A build is a fixed quote and a developer is a monthly rate, both agreed in writing after a 30-minute call.

A focused first buildFixed quoteA tightly scoped build with one core workflow, quoted after a 30-minute call.
A full projectFixed quoteSeveral user roles, integrations and reporting, scoped in writing before work starts.
Dedicated engineerMonthly rateA full-time engineer working on your product, priced per engineer once we know the stack and seniority.

Included as standard

  • UI/UX design, approved before any code
  • Two-factor login and OWASP Top 10 security practices
  • Deployment to production
  • Git repositories and written documentation
  • Two months of free bug fixes after launch

Not included

  • Payment gateways and other premium integrations, quoted separately
  • Graphic design, video and animation
  • Features added mid-build, logged as extra hours

After the free two months, monthly maintenance is available. New features are quoted as you need them, or you can add a dedicated engineer. Book a call and we will price both.

Are we the right team for this?

We’re a good fit if

  • You want AI inside software you already run
  • You need it reliable, not just impressive in a demo
  • You want usage costs under control
  • You want to own the code and the API keys

We’re probably not if

  • Requests for new features get reported as bugs so they don’t count as scope
  • You mainly need graphic design, video or animation
  • You want the lowest price above all else, rather than software that lasts

What I love about Team7 is that they always say: No worries, we can find a solution. This is the mindset of builders, creators, people who do not have fear, the partner you need if you want to excel.

★★★★★
Working with Mo and his team over the past year has been nothing short of exceptional. I was admittedly sceptical about investing such a large amount, but results exceeded every expectation.

★★★★★
Their responsiveness and willingness to take on our challenging task were impressive.
Lisa RubleLicensed Psychologist, COMPASS for Autism · 🇺🇸 Muncie, Indiana
★★★★★
They are amazing and consistently exceed expectations. They go above and beyond what is asked of them and their communication is top notch, so much so that we joke that they never sleep. The best of the best.

Common questions

Straight answers about OpenAI & Claude APIs, cost and how we work.

Ask us something else
OpenAI or Claude?

It depends on the task. We test both on your real examples and pick per feature on quality, speed and cost. The code is written so you can switch provider later without a rebuild.

Who pays for API usage?

You do, on your own OpenAI or Anthropic account, so you see every cost and keep control of the keys. We add limits so usage can’t surprise you.

Is our data used to train the models?

Business API traffic is not used for training by default on either provider. We still keep sensitive fields out of prompts where we can and log what is sent.

What happens after launch?

Bug fixes are free for two months. After that, monthly maintenance is available. New features are quoted as you need them, or you can add a dedicated engineer. We price both on a call.

Who owns the code?

You do. At handover you get the Git repositories and written documentation. There is nothing tying the software back to us, so you can take it to an in-house team whenever you like.

Who will I talk to, and how often?

Rehan, one of our two founders, is your day-to-day contact. You get updates on Slack twice a week and can see the code in your repository at any time. We split working hours between us to cover US, UK and Australian time zones, and we usually reply within an hour, sometimes the next morning.
