AI Girl & Character Generator

Generate AI images of girls, characters, and fictional personas using Media.io OpenAPI. Creates detailed, stylized character portraits in various styles. AI character generator, AI girl generator, character design AI.

Media.io AI Character Generator Skill

Overview

This skill calls Media.io OpenAPI to run character generation using model code character-generator-media-2.0. The API is asynchronous:

1. Submit generation request and get task_id.
2. Poll task result endpoint until the task is finished.

When To Use

• The user wants stylized character images from prompt plus reference image.
• The user can provide an image URL reachable by Media.io servers.
• The user wants task-based generation with polling.

When Not To Use

• The user asks for local file upload only (this API expects image URL input).
• The user asks for non-Media.io providers.
• The user asks for real-time synchronous image output in one call.

Requirements

• Body:

json

{
	"data": {
		"images": "https://example.com/input.jpg",

Request and Response Contract

Common Success Envelope

json

{
	"code": 0,
	"msg": "",
	"data": {},
	"trace_id": "..."
}

Create Task Response

• On success, data.task_id is returned.

Task Result Response

• data.status can be one of the following values:
  • waiting: queued
  • processing: running
  • completed: completed successfully
  • failed: failed
  • timeout: timed out
• data.reason: provides additional context (e.g., success or error message)
• When status is completed:
  • data.result is an array of output objects with generated URLs
  • Each result object contains val (internal path), preview (public HTTPS URL), and status (completion status)

Standard Invocation Flow

1. Call user/credits to verify balance.
2. Call character-generator-media-2.0 with data.images, data.prompt, and optional data.ratio.
3. Extract task_id.
4. Poll generation/result/{task_id} every 3 to 5 seconds.
5. Stop when status is completed or failed.
6. Return output URLs from data.result when completed.

bash

curl --request POST \
	--url https://openapi.media.io/generation/effects/character-generator-media-2.0 \
	--header 'Content-Type: application/json' \
	--header "X-API-KEY: $MEDIAIO_API_KEY" \
	--data '{
	"data": {
		"images": "https://example.com/input.jpg",
		"prompt": "anime style fantasy heroine",
		"ratio": "9:16"
	}
}'

Query Task Result

bash

curl --request POST \
	--url https://openapi.media.io/generation/result/<task_id> \
	--header 'Content-Type: application/json' \
	--header "X-API-KEY: $MEDIAIO_API_KEY" \
	--data '{}'

Successful Response Example

json

{
	"code": 0,
	"msg": "",
	"data": {
		"task_id": "effect-86f0f82a-36dc-4a7c-928a-721a18ef482f",
		"status": "completed",
		"reason": "success",
		"result": [
			{
				"val": "aicloudtmp/550160908/3/202603/1/combo_tm_alg-20260317165022-802800-60eb3-dwt.png",
				"preview": "https://url_to_generated_image.png",
				"status": "completed"
			}
		]
	},
	"trace_id": "a18315ba568b5c34407808d12cbc8457"
}

Response fields when status is completed:

• data.task_id: unique task identifier
• data.status: completed indicates successful completion
• data.reason: success indicates no error occurred
• data.result: array of output objects, each containing:
  • val: internal file path of the generated asset
  • preview: publicly accessible HTTPS URL for the generated asset
  • status: completed for each result item

Error Handling Guidance

• Treat code != 0 as failure.
• Typical authentication errors:
  • 374004: not authenticated. Apply for an APP KEY at https://developer.media.io/.
• Typical request validation error:
  • 490000: params error
• Typical billing/credits error:
  • 490505: insufficient credits. Recharge before invoking generation APIs.
• Always include trace_id in logs for troubleshooting.

Agent Behavior Requirements

• Validate that input contains a non-empty image URL and prompt before calling the create endpoint.
• Do not claim immediate output after task creation; always poll by task_id.
• If credits are insufficient, return a clear message and stop instead of retry loops.
• Avoid exposing raw API keys in logs or responses.

Safety and Compliance Notes

• Only process user-provided or user-authorized images.
• Do not imply identity verification or biometric certainty from generated images.
• Generated output is synthetic media and should be presented as edited content.
