Nano Banana Pro API

Keupayaan

Harga & kredit

Each image costs 4 credits, including all supported resolutions and formats. Credits are reserved on acceptance, settled on success and refunded on failure. Generation times out after 30 minutes; refund_failed means refund recovery is pending.

Request idempotency is not supported. Each valid POST creates a new billable task. If a submission outcome is uncertain, query the returned taskId; retrying POST can create another task.

Pengesahan

Cipta kunci API dalam papan pemuka. Kunci lengkap hanya akan dipaparkan sekali sahaja. Simpan kunci ini pada pelayan anda dan hantarkannya sebagai token Bearer dalam setiap permintaan.

https://api.seevio.ai

Authorization: Bearer sk_live_your_api_key
Content-Type: application/json

Tetapkan pemboleh ubah persekitaran SEEVIO_API_KEY sebelum menjalankan contoh ini. Contoh JavaScript dijalankan pada pelayan anda dengan Node.js; contoh Python menggunakan pakej requests.

Badan permintaan

Parameter input

Aspect ratio defaults to auto. Unknown fields, including output quantity, are rejected. Each request generates exactly one image.

Mula cepat

Hantar permintaan ringkas ini, simpan taskId yang dikembalikan, kemudian gunakan contoh pertanyaan tugasan di bawah. Nilai kredit dalam respons penciptaan ialah amaun yang ditempah.

curl --fail-with-body https://api.seevio.ai/v1/images/generations \
  -H "Authorization: Bearer $SEEVIO_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{
  "model": "nano-banana-pro",
  "input": {
    "prompt": "A minimalist ceramic teapot on a stone pedestal, soft studio lighting",
    "aspect_ratio": "1:1",
    "resolution": "2K",
    "output_format": "png",
    "generation_type": "text-to-image"
  }
}'

Contoh respons cipta tugasan

Teks kepada imej

Generate one image asynchronously per request. Supports text-to-image and image-to-image generation with your Seevio API key.

curl --fail-with-body https://api.seevio.ai/v1/images/generations \
  -H "Authorization: Bearer $SEEVIO_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{
  "model": "nano-banana-pro",
  "input": {
    "prompt": "A minimalist ceramic teapot on a stone pedestal, soft studio lighting",
    "aspect_ratio": "1:1",
    "resolution": "2K",
    "output_format": "png",
    "generation_type": "text-to-image"
  }
}'

Imej kepada imej

For image editing, set generation_type to image-to-image and provide image_urls. All other parameters use the same contract.

Gantikan URL media contoh.com dengan fail HTTPS anda sendiri yang boleh diakses secara awam. URL contoh disediakan hanya untuk menunjukkan struktur permintaan dan bukannya aset sampel yang boleh dimuat turun.

curl --fail-with-body https://api.seevio.ai/v1/images/generations \
  -H "Authorization: Bearer $SEEVIO_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{
  "model": "nano-banana-pro",
  "input": {
    "prompt": "Change the teapot to matte sage green. Preserve its shape and the studio lighting.",
    "aspect_ratio": "1:1",
    "resolution": "2K",
    "output_format": "png",
    "generation_type": "image-to-image",
    "image_urls": [
      "https://example.com/teapot.png"
    ]
  }
}'

Tanya status tugasan

Gantikan ID contoh dengan taskId yang dikembalikan semasa penciptaan. Pertanyaan hanya mengembalikan tugasan milik pengguna kunci API tersebut; ID yang tidak boleh diakses atau tidak dikenali akan mengembalikan ralat HTTP 404.

Lakukan pengundian (polling) setiap 10–20 saat sebagai permulaan, kurangkan kekerapan jika menerima ralat HTTP 429, dan hentikan apabila status bertukar kepada completed atau failed. Sebaik-baiknya gunakan webhook untuk persekitaran pengeluaran. Setiap contoh kod di bawah melakukan satu pertanyaan.

curl --fail-with-body https://api.seevio.ai/v1/tasks/3f2aK9mR7xQp4TnZ8bLc6YwH \
  -H "Authorization: Bearer $SEEVIO_API_KEY"

Gagal

Apabila pertanyaan mengembalikan status=failed, ini bermakna penjanaan telah tamat tetapi gagal. Rujuk failed_reason untuk mengetahui punca kegagalan dan billing_status untuk status bayaran balik. Dalam contoh ini, refunded bermakna kredit telah dikembalikan semula. credits mengekalkan amaun asal yang diketepikan, dan respons ini tidak mengandungi data.

{
  "id": "3f2aK9mR7xQp4TnZ8bLc6YwH",
  "created_at": 1789171200,
  "model": "nano-banana-pro",

  "status": "failed",
  "billing_status": "refunded",
  "failed_reason": "Image generation failed."
}

Result links are provided for 30 days after storage. After expiry, results is empty.

Webhook

Tetapkan callback_url dalam permintaan cipta untuk menerima POST JSON apabila tugasan selesai atau gagal. Kembalikan respons 2xx dalam masa 15 saat. Penghantaran yang gagal akan dicuba semula; proses penghantaran berulang secara idempotensi menggunakan ID tugasan.

Pangkalan akhir (endpoint) panggilan balik anda mesti menerima permintaan POST dengan badan permintaan JSON (Content-Type: application/json).

Cipta tugasan dengan panggilan semula

curl --fail-with-body https://api.seevio.ai/v1/images/generations \
  -H "Authorization: Bearer $SEEVIO_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{
  "model": "nano-banana-pro",
  "input": {
    "prompt": "A minimalist ceramic teapot on a stone pedestal, soft studio lighting",
    "aspect_ratio": "1:1",
    "resolution": "2K",
    "output_format": "png",
    "generation_type": "text-to-image"
  },
  "callback_url": "https://example.com/webhooks/seevio"
}'

Callbacks use the task query response structure; refunded failure notifications also include top-level credits_refunded. Use id to identify the task and status to distinguish completed from failed. Notifications may repeat: process them idempotently by id and status. Callbacks are unsigned; verify the task with the authenticated query endpoint. Delivery failure does not refund a successful task.

Tugasan selesai: muatan panggilan balik yang berjaya

created_at ialah masa penciptaan peristiwa; task_created_at ialah masa penciptaan tugasan, dalam saat Unix. Contoh menunjukkan medan yang disyorkan; respons mungkin mengandungi medan tambahan.

Tugasan gagal: muatan panggilan balik yang gagal

{
  "id": "3f2aK9mR7xQp4TnZ8bLc6YwH",
  "created_at": 1789171212,
  "model": "nano-banana-pro",

  "billing_status": "refunded",
  "failed_reason": "Image generation failed.",
  "task_created_at": 1789171200,
  "credits_refunded": 4
}

Contoh penerima

export async function POST(request: Request) {
  const callbackData = await request.json();

  if (callbackData.status === "completed") {
    const imageUrls = callbackData.data.results;
    // Save the image URLs and mark this task as completed in your application.
    console.log(callbackData.id, imageUrls);
  }

  if (callbackData.status === "failed") {
    const { failed_reason, credits_refunded } = callbackData;
    // Record the failure reason and refunded credits for this task.
    console.error(callbackData.id, failed_reason, credits_refunded);
  }

  return new Response(null, { status: 200 });
}

Contoh Next.js ini membaca badan panggilan balik JSON dan mengendalikan tugasan yang selesai serta gagal secara terus. Tambahkan fungsi persistensi dan penyahduplikasian ID tugasan untuk aplikasi anda; masukkan kerja yang lambat ke dalam giliran (queue) sebelum mengesahkan panggilan balik.

Ralat

Ralat HTTP mengandungi objek ralat dengan kod dan mesej. Tugasan yang berjaya diterima masih boleh gagal kemudian; tanya status tugasan atau kendalikan panggilan semula kegagalannya.

{
  "error": {
    "code": "invalid_request",
    "message": "input.prompt is required."
  }
}

Errors use error.code and error.message: 400 invalid_request, 401 invalid_api_key, 402 insufficient_credits, 403 forbidden, 404 not_found, 429 rate_limited, 500 internal_error. Insufficient provider balance is not a customer 402 error.

Had kadar

Cipta tugasan: setiap kunci API membenarkan sehingga 100 permintaan seminit secara lalai. Had kadar tersuai tidak ditawarkan buat masa ini.

Kueri tugasan: setiap kunci API membenarkan sehingga 120 permintaan seminit secara lalai. Permintaan kueri dan permintaan penciptaan tugasan dikira secara berasingan.

Image and video creation requests share the same API key rate limit.

HTTP 429 menyertakan Retry-After: 60 untuk penciptaan dan Retry-After: 5 untuk pertanyaan. Gunakan fungsi undur masa (backoff) dan elakkan daripada melakukan pengundian lebih kerap daripada yang diperlukan.

HTTP/1.1 429 Too Many Requests
Content-Type: application/json
Retry-After: 60

{
  "error": {
    "code": "rate_limited",
    "message": "Rate limit exceeded."
  }
}
