API interfaces 2026: what has changed
What's different about API interfaces in 2026 compared to two years ago — legally, technically, and regarding what actually pays off for small businesses.
Two things changed for API interfaces in 2026: The EU AI Act transparency requirements came into effect in August, and search engines now answer more and more questions directly in the results. Technically, reliability has improved — which doesn't mean every project makes sense.
01 — Current
What changed recently
Two developments shape the decision in 2026: First, the transparency requirements of the EU AI Act have been in effect since August — anyone communicating with an AI system must be able to recognize it. Second, search itself now answers more and more questions directly, which changes the value of having your own easily findable information source.
For API interfaces, that means in practice: labeling is mandatory, not a stylistic choice, and the content the system works with is the same content that gets quoted in search results and generated answers. Set it up cleanly once, use it twice.
Technically, reliability has improved most of all. What was still an experiment two years ago is today a plannable implementation in many cases — which doesn't mean every project makes sense.
02 — Legal situation
EU AI Act: what applies
Since August 2026, the transparency requirements from Article 50 of the EU AI Act apply: Anyone communicating directly with an AI system must be able to recognize it. We build in the labeling as standard.
The AI Act doesn't distinguish by company size: A sole proprietorship with an AI system in customer contact is affected just as much as a corporation. What matters is purpose and risk, not headcount.
There's also the obligation to ensure adequate AI competence for the people working with it. That's not an examination requirement, but it should be documented — a training session with a participant list is the simplest proof.
03 — Benefits
What it actually delivers
- Time that's missing elsewhere. Between shop and inventory management, between time tracking and payroll, between CRM and accounting, there's a person sitting with an export file.
- Consistent quality. A system doesn't have a bad day and doesn't skip a step — regardless of who's currently in the office.
- Traceability. What runs automatically is documented. That helps with handovers, vacation coverage, and in case of disputes.
- Availability outside business hours. A significant portion of inquiries arise in the evening and on weekends — where until now no one was responding.
- A side effect hardly anyone plans for: During setup, it regularly becomes apparent that processes in the business are unclear. Clarifying that is often more valuable than the automation itself.
04 — Questions
Frequently asked questions
What if our legacy system has no interface?
Then there are usually workarounds: database access, automated file exchange, in exceptional cases surface automation. All are more fragile than a real interface. We'll honestly tell you how stable such a solution will be before you decide.
Is an interface more secure than a manual export?
Significantly, because human errors during export and import are eliminated and every exchange is logged. A manual export leaves no trace if something was overlooked.
What happens during an outage?
The connection remembers what hasn't been transferred yet, tries again, and reports after multiple failed attempts. Data isn't lost, it arrives delayed.
Can multiple systems be connected simultaneously?
Yes, that's actually the more common case — for example, shop, inventory management, and accounting together. Each connection is planned and tested individually, even if everything works together in the end.
What does maintenance cost during operation?
As long as none of the connected systems changes fundamentally, ongoing effort is low — monitoring reports itself when something doesn't fit.
How often is data synchronized?
From immediately to nightly — depending on what's technically necessary. Immediate synchronization isn't always better: for systems with post-processing, a nightly run is often the more stable choice.
Who maintains it later?
You receive code and documentation. We deliberately build with widely used technologies so that switching is possible.
