# Nano banana Pro Bildgenerierung

>  - Asynchroner Verarbeitungsmodus, gibt eine Task-ID für nachfolgende Abfragen zurück
- Hochwertige Bildgenerierung, Bilderstellung auf professionellem Niveau
- Generierte Bildlinks sind 24 Stunden gültig, bitte speichern Sie sie rechtzeitig 

> [!NOTE]
>
> **Hinweis zur Modellnamen-Kompatibilität**: Diese Schnittstelle unterstützt auch den Alias `nano-banana-pro-ext`, der `gemini-3-pro-image-preview` entspricht. Beide sind austauschbar und liefern identische Ergebnisse.

## Autorisierung

**Authorization** `string` *required*

Alle APIs erfordern eine Authentifizierung per Bearer Token

API-Schlüssel erhalten:

Besuchen Sie die [Seite zur Verwaltung von API-Schlüsseln](https://gccai.heqingsong.uk/keys), um Ihren API-Schlüssel zu erhalten

Im Anfrage-Header hinzufügen:

```
Authorization: Bearer YOUR_API_KEY
```

## Body

**model** `string` *required* (default: gemini-3-pro-image-preview)

Name des Bildgenerierungsmodells

Unterstützte Modelle:

* `gemini-3-pro-image-preview` – Standardversion (kompatibler Alias `nano-banana-pro-ext`)
* `gemini-3-pro-image-preview-official` – Offizielle Version (kompatibler Alias `nano-banana-pro`)

Beispiel: `"gemini-3-pro-image-preview"` oder `"gemini-3-pro-image-preview-official"`

> [!NOTE]
>
> Zur Kompatibilität mit älteren Aufrufen können die Aliasnamen `nano-banana-pro-ext` (entspricht `gemini-3-pro-image-preview`) und `nano-banana-pro` (entspricht `gemini-3-pro-image-preview-official`) weiterhin verwendet werden.

**nsfw\_check** `boolean` (default: false)

Legt fest, ob der Inhalt vor dem Absenden des Bildauftrags moderiert wird.

* `true`: Prompts und Eingabebilder mit `omni-moderation-latest` prüfen
* `false` oder nicht angegeben: keine Moderationsanfrage und damit keine zusätzlichen Moderationskosten oder Verzögerung (Standard)

**prompt** `string` *required*

Textbeschreibung für die Bildgenerierung

**size** `string`

Größe des generierten Bildes

Unterstützte Formate:

* Seitenverhältnisse: `auto`, `1:1`, `2:3`, `3:2`, `3:4`, `4:3`, `4:5`, `5:4`, `9:16`, `16:9`, `21:9`

> [!WARNING]
>
> Bei Text-zu-Bild ist der Standardwert `1:1` oder `16:9`, wenn `size` auf `auto` gesetzt ist; bei Bild-zu-Bild richtet sich das Seitenverhältnis nach der Antwort der vorgelagerten Quelle. Wir empfehlen, ein Seitenverhältnis explizit anzugeben.

**n** `integer`

Anzahl der zu generierenden Bilder

Bereich: 1

Standard: 1

**⚠️ Hinweis:** Muss eine reine Zahl sein (z. B. `1`), keine Anführungszeichen verwenden, sonst tritt ein Fehler auf

**resolution** `string`

Auflösung des Ausgabebildes

Unterstützte Werte:

* `1K` – 1K-Auflösung (Standard)
* `2K` – 2K-Auflösung
* `4K` – 4K-Auflösung

**⚠️ Hinweis:** Die Generierung von 4K-Bildern im Base64-Format nimmt mehr Verarbeitungszeit in Anspruch

**official\_fallback** `boolean` (default: false)

Ob der offizielle Fallback-Kanal verwendet werden soll

* `false`: Nicht verwenden (Standard)
* `true`: Offiziellen Kanal verwenden

> [!WARNING]
>
> Bei Verwendung des offiziellen Kanals (`gemini-3-pro-image-preview-official`) kann dieser Parameter nicht verwendet werden.

**image\_urls** `array`

Liste der URLs von Referenzbildern für Bild-zu-Bild-Generierung oder Bildbearbeitung

**💡 Schnelleingabe (Try-it-Bereich):**

1. Klicken Sie auf „+ Add an item", um eine Bild-URL hinzuzufügen
2. Geben Sie die vollständige Bild-URL oder Base64-Daten ein

**Detaillierte Feldbeschreibung**

Jedes Element des Arrays ist eine Zeichenkette, es werden zwei Formate unterstützt:

**1. Vollständige Bild-URL**

* Öffentlich zugängliche Bild-URL (http\:// oder https\://)
* Beispiel: `"https://example.com/image.jpg"`

**2. Base64-kodiertes Format**

* **Vollständiges Data-URI-Format muss verwendet werden**
* Format: `data:image/{format};base64,{base64data}`
* Unterstützte Bildformate: jpeg, png, webp usw.
* Beispiel: `"data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABg..."`
* ⚠️ Hinweis: Das Präfix `data:image/jpeg;base64,` muss enthalten sein

**Einschränkungen:**

* Ein einzelnes Bild darf 30 MB nicht überschreiten
* Unterstützte Formate: .jpeg, .jpg, .png, .webp

**Limit:** Maximal 14 Bilder

## Response

**code** `integer`

Statuscode der Antwort

**data** `array`

Array mit Antwortdaten

**Eigenschaften**

**status** `string`

Aufgabenstatus

* `submitted` – Eingereicht

**task\_id** `string`

Eindeutige Aufgabenkennung
