Seedance 2.5 API-Referenz

Mit einem einzigen PopNow-API-Schlüssel rufst du Seedance 2.5 aus deinem eigenen Code auf. Hier findest du die Modell-IDs, jedes Eingabefeld, die Kosten pro Anfrage in Credits und eine Anfrage, die du direkt ins Terminal kopieren kannst.

Die Parameterbeschreibungen stammen aus dem Eingabeschema des Modells und sind nur auf Englisch verfügbar.

Auf einen Blick

Hersteller: ByteDance
Ergebnis: Video
Ab: 11.07 Credits pro Sekunde Ergebnis ($0.1107)

1 Credit = 0,01 $. Bei Annahme reserviert ein Task den höchstmöglichen Betrag und rechnet am Ende den tatsächlichen Verbrauch ab, auf ganze Credits aufgerundet; der Rest wird freigegeben. Fehlgeschlagene Tasks kosten nichts. Den genauen Betrag vorab liefert POST /api/v1/jobs/quote.
