FAQ — API Development Düsseldorf
(01)How much does API development cost in Düsseldorf?
We work on a fixed-price basis so you know the cost upfront. Fixed price after scoping. Proposal within 48 hours. After a short discovery call we give you a clear, no-obligation quote.
(02)How long does it take to build and launch an API?
Most projects go live in four to eight weeks. We start with discovery in week one, deliver a working prototype by week three, and have the production interface integrated by week four — then extend it as your needs grow.
(03)How is API development different from building a chatbot?
A chatbot is a conversational front end for users. API development is the plumbing behind your systems: it connects shops, CRMs, ERPs and partner platforms so data moves automatically. APIs can power a chatbot, but their core value is reliable, machine-to-machine integration.
(04)Do you need access to our internal systems and data?
We integrate against the systems the API must connect, using scoped, read- or write-limited credentials. Access is granted only to what is needed, secured with authentication and audit logging, and can run entirely within your EU infrastructure or on-premise.
(05)Is the solution GDPR-compliant?
Yes. We build with data protection by design — EU hosting, encrypted transfer, access controls and audit trails. Where leading language models are involved, we select options that keep your data within compliant boundaries, and on-premise deployment is available.
(06)Can you work remotely with our Düsseldorf team?
Yes. We work efficiently remote for day-to-day development and join you on-site in Düsseldorf for kickoff workshops and key milestones. You also receive code usage rights, so your team can maintain and extend the interface independently.
