SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Retrieving fax history from the Sinch Fax API normally requires writing HTTP requests with OAuth2 authentication and handling pagination manually. This Skill performs the API call directly and formats the results for immediate review. ## Core Features & Use Cases - Fax Listing: Retrieve sent and received faxes for your Sinch project via GET /v3/projects/{projectId}/faxes. - Flexible Output: Display results as a readable table (id, to, status, createdAt) or as raw JSON. - Pagination Support: Control the number of results returned with a page-size option. - Use Case: A support engineer needs to verify whether a customer's fax was delivered; they run the list command and inspect the status column for the relevant recipient. ## Quick Start Ask the assistant to list recent faxes from your Sinch account, optionally requesting JSON output or a specific page size.
