Public API for Your Software

If you run a software product, we build a public API for it — with keys your customers create themselves, sensible limits per plan, a developer website with examples, and tests that stop it breaking.

Why you need it — Without it you would need a specialist engineer for months, and customers may leave for tools that connect to their other systems. With it, customers build on your product instead.
  • Pilot the plan to start small
  • Inspected before it goes live
  • Monthly or every 3 months, or yearly
  • 2–4 days build time, once your material is in
Free first step

Get a free proposal for your business, in minutes

Tell us your business name and we email you what this service would do for it, what we need and the fixed price. No account, no payment.

We use your email only to send this and to answer you.

When you order: a full refund if you cancel before work starts, and if a delivery does not contain what this page lists, we fix it, rebuild it or refund that part.

What you get

  • Public API for your main product data, with version control and a written specification
  • Customers create and control their own access keys in their account settings
  • Usage limits set by price plan
  • Developer website with a try-it-out reference and code samples
  • AI assistant that answers developers' questions
  • Ready-made code packages for two programming languages
  • Automatic tests that stop changes from breaking the API

How your order runs, after you choose a plan

  1. Questionnaire

    You answer a short questionnaire about your business, your goals and what this service needs.

  2. Five sample concepts

    We prepare five sample designs of your site from your answers, each with its own look and layout.

  3. You choose or mix

    Pick one, or mix them — for example the colours of one with the layout of another.

  4. Upload your material

    Send what this service works from — files, data, access or material, depending on the service. We use only what you give us.

  5. We build it

    Our specialist AI team builds the complete service from your choice and your material.

  6. Quality inspector

    An automated inspector checks the work. Anything that fails is rebuilt before you see it.

  7. Live

    Your site goes live at a web address we give you, then on your own domain.

The five samples usually arrive within minutes. Each service's build time is counted from the day your questionnaire and material are complete.

How it works

What it does for you, every day, once it is live.

  1. 1Answers developer questions in the portal from your API docs
  2. 2Writes code samples for new endpoints from the spec

How we deliver it

Live on the web, hosted by us
We build it and put it live for you: first at a web address we give you, then on your own domain once you add one DNS record (we show you which). We run the hosting and the security certificate; you follow it and ask for changes from your dashboard.
The API and developer portal run live on your own domain with keys and limits working; we build, host and maintain them.
Every plan keeps it live and includes care rounds every month — changes, fixes and help; a bigger plan includes more.

Choose your plan

Every plan includes the complete service. A bigger plan includes more usage.

What we need from you

We use only what you give us — we never invent your details.

  • Which objects should the API expose first?
  • How do customers sign in today?
  • What limits fit each plan?
  • Which two languages do customers code in?
  • Who owns API changes?

Your data stays yours.

The promise, in plain words — and each part is built into how we work, not just written here.

Encrypted, per customer

Everything you send us is encrypted with keys that belong to your account alone.

Used only for your service

Your files and answers are used to build your service — never for another customer's work.

No outside AI without approval

Data you mark confidential is not sent to any outside AI service we have not approved. By default it is handled only by our own tools.

Delete everything, any time

From your account you can delete everything you sent us and everything built from it. Your keys are destroyed, so even backups become unreadable, and you get a deletion receipt. Only the invoice records that accounting law requires are kept.

Add-ons & upgrades

Start with the build, then add what you need — anytime.

Usage top-up — Developer questions answered: 20
Extra usage for this service (Developer questions answered), added to your plan. Valid for 12 months and used only after what is already included runs out.
