ONEPOST — Data Boxes

What it is: ONEPOST is an ATLAS GROUP application for working with Czech data boxes. The ONEPOST - datové schránky add-on connects CODEXIS AI Agent to your ONEPOST account: the Agent can then read messages and attachments from your connected data boxes, search them, and prepare and send a data message on your instruction.

The connection takes three steps: install the add-on, click Otevřít ONEPOST (Open ONEPOST) in the application and choose the access type, then paste the generated API key back into the application.

1. Install the add-on

1. Open Add-ons in the left-hand menu.
2. Use the Search add-ons… box to find the ONEPOST - datové schránky card in the Law category.
3. Click Install.

2. Generate an API key in ONEPOST

For the Agent to reach your data boxes, it needs an API key from your ONEPOST account. You get to ONEPOST from the application in the Agent:

1. Go to Tools → Applications in the left-hand menu and open the ONEPOST - datové schránky application.
2. In the application, open ONEPOST API klíč and click the Otevřít ONEPOST (Open ONEPOST) button.

3. ONEPOST opens straight with the Codexis - AI agent dialog. Choose the access type:
   • Pouze čtení (read only): the Agent reads data boxes, messages and attachments and searches them. It cannot make any changes.
   • Čtení a akce (read and actions): the Agent can additionally perform permitted actions on your behalf, for example send data messages.

4. The key is created as soon as you choose. Copy it with the Kopírovat (Copy) button.

3. Paste the key into the application in the Agent

1. Go back to the ONEPOST API klíč page in the Agent.
2. Paste the copied key into the Vložte klíč z ONEPOSTu (Paste the key from ONEPOST) field.
3. Click Uložit a ověřit (Save and verify). The Agent verifies the key right away.

4. Work with data boxes in the chat

From now on you ask the Agent about data messages in plain language. With data boxes the Agent can:

• list your connected data boxes and their folders;
• check for new, unread or recently received messages;
• search messages by subject or text;
• open a message's details: sender, recipient, date, subject and attachments;
• download individual attachments;
• evaluate the content of attachments, including PDF documents;
• create a draft data message with attachments;
• send a prepared draft, but only on your explicit instruction;
• receive current messages from ISDS into ONEPOST.

There is no special procedure: open a regular chat, select the ONEPOST - datové schránky skill and ask in plain language, the Agent understands the instruction. Write for example: "Find all data messages from the tax office from the last week."

💡 In practice: Ask in the morning what's new in your data box, have the attachments of an incoming message summarized, or have a draft reply prepared with attachments. Sending is always confirmed by you.
