Verdicts

ArtCraft

Public source under permissive licences. No external-agent API verified.

Melius

One backend serves a 59-operation REST API with a public OpenAPI spec, a hosted MCP server with OAuth sign-in and a JSON-only CLI, and the status page shows no incidents since July 2026. API keys carry no scopes and work with their creator's role, and no rate-limit numbers, changelog or per-model credit prices are published.

Before you call either

ArtCraft

  1. Use the interactive application unless an official automation interface is confirmed.
  2. Check the model service terms before sending private reference media.

Melius

  1. Generate by creating a node on a canvas, starting a run with POST /nodes/{nodeId}/runs, then polling GET /node-runs/{nodeRunId} until status is finished or failed
  2. Over MCP, call get_guide first, show_presence before node changes and canvas_plan_layout before bulk_create_nodes
  3. On 429 wait Retry-After seconds. After a timeout or 5xx on a write, read the canvas or run state before resubmitting, because there are no idempotency keys
  4. Read credit costs from GET /generation/models?category=image before a bulk run. A 400 can mean the team is out of credits
  5. Downloads arrive as a ZIP from a signed URL. Fetch that URL without the Authorization header
