Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

fax

get_fax_price

Zeigt den Preis für ein Fax (Pay per Fax, Endpreise, gemäß §19 UStG ohne Umsatzsteuer) und prüft, ob die Faxnummer erlaubt ist. Sendet nichts.

get_fax_status

Liefert den Status eines Faxes (Zahlung ausstehend, geplant, wird gesendet, zugestellt, fehlgeschlagen, storniert) und nach Zustellung den Link zum Sendebericht.

send

send_fax

Bereitet ein echtes Fax über SofortFax vor und liefert einen sicheren Stripe-Bezahllink (2,49 € – 4,99 €). Das Fax wird erst nach der Zahlung gesendet. Vorher dem Nutzer Faxnummer, Dokument und ggf. Sendezeitpunkt bestätigen lassen. DOKUMENT (genau eines): "upload_id" aus create_upload_link (für Dateien/Fotos auf dem Gerät), "file" (in ChatGPT angehängte Datei, wird automatisch befüllt), "document_url" (direkter öffentlicher HTTPS-Link zu PDF/JPG/PNG) oder "document_base64" (nur sehr kleine Dateien, max. 700 KB). Bestätigung, Zustellbericht (Sendebericht) und Rechnung kommen per E-Mail an "email". Das Ergebnis sagt eindeutig, ob das Fax gesendet, geplant oder noch unbezahlt ist.

upload

create_upload_link

Erstellt einen sicheren Einmal-Upload-Link (30 Minuten gültig) für das Fax-Dokument: PDF, JPG, PNG oder direkt ein Foto mit der Handykamera, max. 10 MB. Der Nutzer öffnet upload_url und lädt die Datei hoch; danach send_fax mit der upload_id. Kostet nichts und sendet nichts.
