Invoice API for AI agents

Send structured invoice data, get a finished PDF back. This service is built to be used by AI agents together with the invoice-generator skill, which turns a plain text file of invoice details into the right API call.

How it works with the skill

  1. You keep your invoice details in any text file, however messy.
  2. The agent reads the skill, organizes the information and asks you for anything missing.
  3. It calls this API and downloads your PDF invoice.

Install the skill from github.com/hasinhayder/invoice-generator-skill.
