REST + MCP

API Komik

Use the Comic API to turn prompts, customer uploads, character references, and story briefs into structured comic pages with generated panel assets.

Pengesahan

Send your API key with HTTP Bearer Auth on every request.

1Authorization: Bearer $LLAMAGEN_API_KEY

Base URL

All production REST endpoints use the same API host. MCP clients can connect from the docs workflow.

MCP Usage

Connect via Streamable HTTP

MCP Endpoint
https://llamagen.ai/api/mcp
Authorization Header
Authorization: Bearer YOUR_API_TOKEN

Configure your MCP client to use Streamable HTTP transport with the endpoint above. Provide your API token via the Authorization header.

Available Tools

  • create_comic_generation— Create a generation job
  • get_comic_generation_status— Get status/result by id
  • get_api_usage— View current usage and quota

Client Configuration Example

Many MCP clients allow setting a remote HTTP endpoint with custom headers. Below is a generic example:

{
  "mcpServers": {
    "llamagen": {
      "url": "https://llamagen.ai/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_TOKEN"
      }
    }
  }
}

The exact configuration format varies by client. Ensure the Authorization header is set with your token.

Cursor Setup

  1. Open Cursor Settings and find the Model Context Protocol (MCP) section.
  2. Add a new server using Streamable HTTP.
  3. Set URL to https://llamagen.ai/api/mcp.
  4. Under Headers, add Authorization: Bearer YOUR_API_TOKEN.
  5. Save and test by listing tools; you should see create_comic_generation, get_comic_generation_status, get_api_usage.

Alternatively, you can configure via Cursor's MCP configuration file using the same JSON structure as above, if your version supports it.

SDK Quick Start

Install the SDK first, then create a generation job and wait for the final result in two clear steps.

Install

 npm i comic

Step 1: Create generation

1import { LlamaGenClient } from 'comic';2 3const llamagen = new LlamaGenClient({4  apiKey: process.env.LLAMAGEN_API_KEY!,5});6 7const created = await llamagen.comic.create({8  prompt: 'A detective fox in Tokyo',9  size: '1024x1024'10});

Step 2: Wait for completion

1const result = await llamagen.comic.waitForCompletion(created.id);2 3console.log(result);

Supported size values: 1024x1024 (1:1), 512x768 (2:3), 512x1024 (1:2), 576x1024 (9:16), 768x1024 (3:4), 1024x768 (4:3), 768x512 (3:2), 1024x576 (16:9), 1024x512 (2:1)

TypeScript Types

The SDK ships with first-class TypeScript types for request payloads and responses.

1import type {2  CreateComicParams,3  ComicArtworkResponse,4  ComicGenerationStatus5} from 'comic';6 7const payload: CreateComicParams = {8  prompt: 'A superhero cat saving a city',9  preset: 'render',10  size: '1024x1024'11};

Valid size values: 1024x1024 (1:1), 512x768 (2:3), 512x1024 (1:2), 576x1024 (9:16), 768x1024 (3:4), 1024x768 (4:3), 768x512 (3:2), 1024x576 (16:9), 1024x512 (2:1)

Status Lifecycle

StatusMeaning
LOADINGRequest accepted or generation is still running.
PROCESSEDGeneration completed successfully.
FAILEDGeneration failed. Inspect error details.

Recommended: poll every 3-5 seconds with timeout protection and exponential retry for transient failures.

Webhooks

Manage webhook endpoints in Settings → API → Webhooks. You can subscribe to create, update, completed, and failed events for comic generations.

Supported Events

  • comic.generation.created — Fires after a generation request is accepted.
  • comic.generation.updated — Fires after continue-write or single-panel regenerate is queued.
  • comic.generation.completed — Fires when the generation reaches a processed state.
  • comic.generation.failed — Fires when the generation ends in a failed state.

Signing Headers

X-Llama-Webhook-Id: evt_...
X-Llama-Webhook-Timestamp: 1715510400
X-Llama-Webhook-Signature: v1=...
X-Llama-Webhook-Request-Id: req_...

Compute the signature from ${timestamp}.${rawBody} using your webhook secret. The dashboard only shows the secret once when creating or rotating it.

Request Logs

In dashboard settings, use Request Logs to trace endpoint usage, status codes, latency, and credit changes for each API call.

Keep a request ID in your app logs and correlate it with dashboard request logs for faster debugging.
