What is ECMWF Web API
ECMWF WebAPI is a set of services developed by ECMWF to allow users from the outside to access some internal features and data of the centre.
In this page you will find explanations, guides and examples showing how to use the different ECMWF WebAPI services.
This external access is limited and managed by the User Profile access (Member State, Commercial customers, ECMWF staff member...). Some of these services are public and some other are restricted to the Archive Access.

| Authorized user | MARS catalogue (Authorization required, browse and download) | Access MARS |
| Commercial user | Archive catalogue (Only browse) MARS catalogue (Authorization required, browse and download) | Access MARS |
