oc_prompt, then the selected rendering backend creates the image. The request returns an asynchronous img_uuid for polling or callback handling.OC Maker API for Original Character Generation
Add a two-stage character workflow to your product through GoEnhance. Your prompt guides a language model to produce structured character data with an

Turn Character Briefs into Structured, Rendered Results
Shape the Character Data
Supply the full text-stage prompt and define the JSON fields your application needs. The response must contain oc_prompt, while fields such as role name, appearance, personality, or backstory can pass through with the generated character data.
Choose the Rendering Path
Select seedream or gpt-image-2 for the image stage, and optionally set a supported ratio. A request-level ratio overrides oc_ratio from the generated JSON, keeping layout decisions under application control.
Build against the documented request and result contract rather than assuming a generic image endpoint.
OC Maker API Capabilities
Two-Stage Generation
One request runs structured character creation first and image rendering second.
Custom Prompt Contract
Define the text-stage instructions and require parseable JSON with an <code>oc_prompt</code> field.
Flexible Character Fields
Request extra fields such as appearance, personality, role name, or backstory for downstream use.
Rendering Backend Choice
Set <code>image_render_model</code> to <code>seedream</code> or <code>gpt-image-2</code>.
Supported Output Ratios
Choose 1:1, 2:3, 3:2, 4:3, 3:4, 16:9, or 9:16; the default is 3:4.
Asynchronous Result Handling
Persist <code>img_uuid</code>, then poll job details or process a public HTTPS callback.
The documented rate covers both the language-model and image-rendering stages in one billed request.
OC Maker API Pricing
1 Token per Request
Each OC Maker request costs 1 GoEnhance token across both processing stages.
$0.02 per Request
The current documented USD equivalent is $0.02 for a complete OC Maker request.
Failed Jobs Refunded
The documentation states that a failure in either stage fails the whole job and refunds the tokens.
Integrate the OC Maker API in Four Steps
1
1. Write the text-stage prompt
Tell the model to return only parseable JSON containing
oc_prompt. Add any character fields your application needs. 2
2. Configure the render
POST
model: oc-maker, your prompt, and a required image_render_model. Optionally set the output ratio, text model, system prompt, or callback URL. 3
3. Track the job and read both results
Validate the submission response and persist
data.img_uuid with your own task record. Poll GET /api/v1/jobs/detail or process callbacks until terminal state, then read the structured object from the JSON entry and the asset URL from the image entry.Use structured character data and a matching visual where both outputs support the same product workflow.
OC Maker API Use Cases
Roleplaying Character Builders
Generate a character profile and a corresponding visual for review inside a roleplaying tool.
Game Concept Pipelines
Turn structured briefs into early character records and images for a human-led concept process.
Story Development Tools
Create appearance, personality, and backstory fields alongside a visual reference for writers.
Avatar Creation Flows
Collect user choices, compose a controlled prompt, and return a generated character portrait or full-body result.
Creative Prototype Apps
Test character ideas while retaining structured data that can feed editing or approval interfaces.
Automated Asset Workflows
Connect task completion to moderation, storage, review, and downstream content systems.
