List all active companies in my NFe.io account.

I've retrieved your company list. You have 2 active entities: 1. Tech Services Ltda (ID: comp_1), 2. Consulting Group (ID: comp_2). Which one would you like to use for invoice issuance?

Check the status of service invoice ID 'inv_nfe_999888'.

Connecting to NFe.io gateway... Invoice 'inv_nfe_999888' is currently 'Issued' (Autorizada). I've found the official download links: [Download PDF](...) and [Download XML](...). Would you like me to send these to you?

Find the IBGE code for the city of 'São Paulo'.

Searching municipal codes... I found the IBGE code for São Paulo (SP): `3550308`. This code is active and compatible with the NFe.io service invoice engine.

Yes! Use the `issue_service_invoice` tool with the Company ID and a JSON payload containing the customer data and service values. Your agent will trigger the issuance process with the relevant municipality.
