How do I get my Loyverse API token?

Log in to your Loyverse Back Office. Navigate to the Integrations section, specifically 'Access Tokens'. Here, you can generate a new personal access token specifically for this AI integration.

Can I query daily sales reports?

Yes, you can use the `l_list_receipts` tool to retrieve sales data and individual receipts over any date range, and the AI agent can aggregate these into daily sales reports for you.

Does the API support checking inventory?

Absolutely. You can use the `l_list_items` tool to dynamically track item catalog details and stock presence across your system.

Can I see all my registered customers?

Yes. The `l_list_customers` tool lets the agent fetch your entire customer database, including their names, registration dates, and generated identifiers.
