概要

テキストプロンプトから高品質で編集可能なベクターグラフィックアセットを生成します。Bria 独自の text-to-image 基盤モデルを使用して、拡張可能なアイコン、ロゴ、イラストの作成に適しています。

このインターフェースは https://engine.prod.bria-api.com/v1/text-to-vector/base/3.2 と同等です詳細は、Bria 公式ドキュメントを参照してください。

使用するタイミング

最終的なアセットを編集可能または拡張可能なままにしておく必要がある場合、たとえばアイコン、シンプルなイラスト、ロゴ、レイアウトグラフィックなどで、このエンドポイントを使用します。写真のようなリアルな細部や複雑なテクスチャが必要な場合は、代わりにラスター画像生成を使用してください。

最初のリクエスト

オブジェクト、スタイル、用途を説明する短いプロンプトから始めます。最初のリクエストはシンプルに保ち、ベクター出力が実用的であることを確認してから、ブランド、色、構図の制約を追加してください。

レスポンスの読み方

レスポンスは API playground を通じてベクター出力フィールドを返します。ワークフローで長期保存や後からの編集が必要な場合は、返されたアセットを速やかに保存してください。

承認

Authorization

string

header

必須

Bearer token authentication. Use your CometAPI key.

ヘッダー

Content-Type

string

ボディ

application/json

prompt

string

デフォルト:A flat vector illustration of a sailboat at sunset

必須

The prompt you would like to use to generate images. Bria currently supports prompts in English only.

guidance_method_2_scale

integer

デフォルト:1

必須

The impact of the guidance.

Default 1

num_results

integer

The aspect ratio of the image. When a ControlNet is being used, the aspect ratio is defined by the guidance image and this parameter is ignored. Default 4

sync

boolean

Determines the response mode. When true, responses are synchronous. With false, responses are asynchronous, immediately providing URLs for images that are generated in the background. Use polling for the URLs to retrieve images once ready. Default false

aspect_ratio

string

The aspect ratio of the image.

Default "1:1"

Enum "1:1" "2:3" "3:2" "3:4" "4:3" "4:5" "5:4" "9:16" "16:9"

seed

integer

You can choose whether you want your generated result to be random or predictable. You can recreate the same result in the future by using the seed value of a result from the response with the prompt, model type and model version. You can exclude this parameter if you are not interested in recreating your results. This parameter is optional.

negative_prompt

string

Specify here elements that you didn't ask in the prompt, but are being generated, and you would like to exclude. This parameter is optional. Bria currently supports prompts in English only.

steps_num

integer

The number of iterations the model goes through to refine the generated image. This parameter is optional. Default 30

text_guidance_scale

integer

Determines how closely the generated image should adhere to the input text description. This parameter is optional. Default 5

prompt_content_moderation

boolean

When enabled (default: true), the input prompt is scanned for NSFW or ethically restricted terms before image generation. If the prompt violates Bria's ethical guidelines, the request will be rejected with a 408 error. Default true

content_moderation

boolean

When enabled, applies content moderation to both input visuals and generated outputs.

For input images:

Processing stops at the first image that fails moderation
Returns a 422 error with details about which parameter failed

For synchronous requests (sync=true):

If all generated images fail moderation, returns a 422 error
If some images pass and others fail, returns a 200 response with successful generations and "blocked" objects for failed ones

For asynchronous requests (sync=false):

Failed images are replaced with zero-byte files at their placeholder URLs
Successful images are stored at their original placeholder URLs

Default false

ip_signal

boolean

Flags prompts with potential IP content. If detected, a warning will be included in the response.

Default false

guidance_method_1

string

Which guidance type you would like to include in the generation. Up to 2 guidance methods can be combined during a single inference. This parameter is optional. Enum "controlnet_canny" "controlnet_depth" "controlnet_recoloring" "controlnet_color_grid"

guidance_method_1_scale

integer

The impact of the guidance.

Default 1

guidance_method_1_image_file

string

The image that should be used as guidance, in base64 format, with the method defined in guidance_method_1. Accepted formats are jpeg, jpg, png, webp. Maximum file size 12MB. If more then one guidance method is used, all guidance images must be of the same aspect ratio, and this will be the aspect ratio of the generated results. If guidance_method_1 is selected, an image must be provided.

guidance_method_2

string

guidance_method_2_image_file

string

The image that should be used as guidance, in base64 format, with the method defined in guidance_method_2. Accepted formats are jpeg, jpg, png, webp. Maximum file size 12MB. If more then one guidance method is used, all guidance images must be of the same aspect ratio, and this will be the aspect ratio of the generated results. If guidance_method_1 is selected, an image must be provided.

image_prompt_mode

string

regular: Uses the image’s content, style elements, and color palette to guide generation.
style_only: Uses the image’s high-level style elements and color palette to influence the generated output. The support for image prompt is currently available only when model_version="2.3".

Default "regular"

Enum "regular" "style_only"

image_prompt_file

string

The image file to be used as guidance, in base64 format. Accepted formats are jpeg, jpg, png, webp. The support for image prompt is currently available only when model_version="2.3". Maximum file size 12MB. This image can be of any aspect ratio, even when it's not alligned with the one defined in the parameter 'aspect_ratio' or by visuals provided to the ControlNets.

image_prompt_urls

string[]

A list of URLs of images that should be used as guidance. The images can be of different aspect ratios. Accepted formats are jpeg, jpg, png, webp. The URLs should point to accessible, publicly available images. The support for image prompt is currently available only when model_version="2.3".

url

image_prompt_scale

integer

The impact of the provided image on the generated results. A value between 0.0 (no impact) and 1.0 (full impact). Default 1

レスポンス

200 - application/json

Success

The response is of type object.
