Alerts come to you

Rather than checking the alerts page every day, you can subscribe to an RSS feed: each new record appears automatically in your feed reader, your mailbox or your management tool.
The feed is free and open to everyone. It comes in several variants: global, by country, by type of property or combined. It is updated as soon as an alert is published.
This page explains how to subscribe, which filters to choose and how to build the feed into your tools.

How to subscribe
Choose the feed that suits you — global, by country, by category or combined — then copy its address into your feed reader (or click the subscription button). No account is needed for the public feeds.
Professional accounts can also receive enriched feeds, containing the detailed data of the records. These are secured by a personal key that must not be shared.



What the feed contains
Each item in the feed corresponds to an alert: title, publication date, country, category, thumbnail, summary of identifying details and link to the full record. Significant changes to a record (withdrawal, recovery, update) also appear.
The feed is offered in RSS, Atom and JSON. The JSON format is intended for developers: it makes it possible to build alerts into a management software, a website or a mobile application.
Professional uses
Auction houses connect the feed to their cataloguing system: each new alert is automatically compared with current lots. Platforms build it into their moderation. Museums use it to inform their security teams.
A simple use is to receive the feed in one's mailbox: several tools turn feeds into daily emails. It is a practical solution for small organisations that have no developer.
The feed and data protection
The public feed contains only the information needed for recognition. Reporters' identities, contact details and investigation circumstances never appear in it. The professional feed follows the same rules and adds fields reserved for approved operators.
Every access is logged, and anomalies (high request volumes, access from unusual addresses) are analysed. Misuse leads to suspension of the key.
Which feed to choose
| Feed | Content | For whom |
|---|---|---|
| Global | All alerts | Institutions |
| By country | Alerts of one State | Customs |
| By category | Alerts for one type of property | Specialists |
| Combined | Country and category | Targeted operators |
| Professional | Detailed data | Approved accounts |
