Parameter
Diese Felder stammen aus demselben Schema, gegen das wir jede Anfrage prüfen. Nicht aufgeführte Felder werden abgelehnt.
image_urlstringPflichtDas Bild, von dem aus es losgeht.
generate_texturebooleanOptionalBeeinflusst den PreisDie Oberfläche des Meshes mit einer Textur versehen. Standardmäßig an; ausgeschaltet entfällt die Textur nur, wenn auch generate_pbr aus ist.
generate_pbrbooleanOptionalBeeinflusst den PreisPBR-Materialkarten hinzufügen (Metall-Rauheit und Normal). Standardmäßig an und aktiviert die Textur.
texture_qualitystringOptionalBeeinflusst den PreisTexturauflösung: standard (Standard) oder detailed. detailed kostet mehr und gilt nur für texturierte Meshes.
geometry_qualitystringOptionalBeeinflusst den PreisGeometriedetail: standard (Standard) oder detailed. detailed erzeugt feinere Oberflächendetails und kostet mehr.
quad_meshbooleanOptionalBeeinflusst den PreisVierseitige (Quad-)Polygone statt Dreiecke zurückgeben, zur Bearbeitung in Modellierprogrammen; die Datei kommt dann als FBX statt GLB zurück. Standardmäßig aus; erhöht den Preis.
face_limitintegerOptionalZiel-Flächenanzahl von 1.000 bis 2.000.000. Leer lassen, damit das Modell entscheidet (oft über eine Million Flächen). Ändert den Preis nicht.
model_orientationstringOptionaldefault behält die Standardausrichtung bei; align_image dreht das Modell passend zum Bild.
texture_alignmentstringOptionalDie Textur am Originalbild (Standard) oder an der erzeugten Geometrie ausrichten.
auto_sizebooleanOptionalDas Mesh auf geschätzte reale Abmessungen skalieren. Standardmäßig aus.
seedintegerOptionalVerwende denselben Seed und dieselben Einstellungen für besser kontrollierte Vergleiche.
texture_seedintegerOptionalSeed für den Texturschritt. Seed unverändert lassen und diesen Wert ändern, um auf derselben Form neue Texturen zu testen.

}Antworten, Polling und Callbacks
Der Ablauf ist für alle Modelle gleich: Erstelle einen Auftrag und frage seinen Status ab oder warte auf den Callback.
Erst den Preis prüfen
curl -X POST https://api.popnow.ai/api/v1/jobs/quote \
-H "Authorization: Bearer $POPNOW_API_KEY" \
-H "Content-Type: application/json" \
-d '{

"texture_quality": "standard",
"geometry_quality": "standard",
"model_orientation": "default"
}
}'Sende vor dem Start denselben Anfrage-Body an POST /jobs/quote, um die geschätzten und maximalen Kosten in USD zu sehen. Die Preisabfrage führt keine Aufgabe aus und belastet dein Guthaben nicht.
Angenommen
HTTP/1.1 202 Accepted
{

},
"request_id": "req_example_create"
}HTTP 202 bedeutet angenommen: Der USD-Höchstbetrag bleibt bis zur Abrechnung reserviert. Bei Annahme einer Aufgabe reservieren wir den maximalen Angebotsbetrag aus deinem API-Guthaben. Nach Abschluss rechnen wir den tatsächlichen Verbrauch ab, höchstens den reservierten Betrag, und geben den Rest frei. Schlägt die Aufgabe fehl, wird die Reservierung aufgehoben.
Status abfragen
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
-H "Authorization: Bearer $POPNOW_API_KEY"Frage den Status im Abstand einiger Sekunden ab und verlängere die Abstände schrittweise. Beende die Abfrage, sobald state den Wert succeeded, failed, canceled oder expired hat.
