Mark several invoices as paid on one credit date.

Számlázz.hu API: https://cotlet.dev/docs/api/szamlazz-hu.md

`POST https://cotlet.dev/api/v1/szamlazz-hu/invoices/settle`

Access: write. Confirm: waits for the user's OK before it runs.

Does what Bizonylatok kiegyenlítése does in the invoice list: marks the selected invoices as settled and gives all of them the same credit date. The app cannot undo it, and a wrong date is corrected one invoice at a time. Returns the invoices that were settled. Needs a paid package and permission to manage payment status. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `invoice_numbers` | array | yes | Invoice numbers from list_invoices. |
| `date` | date | yes | Credit date for all of them. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
