Verdicts

ArtCraft

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

Seedream on BytePlus ModelArk

Per-image prices from $0.018 are public, and API keys can be limited to named models and an IP allowlist. No status page, SLA or OpenAPI file was found, onboarding needs a browser sign-up, and BytePlus says its model services are not available in the United States.

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.

Seedream on BytePlus ModelArk

  1. POST to https://ark.ap-southeast.bytepluses.com/api/v3/images/generations with Authorization: Bearer $ARK_API_KEY. Keys and model activation are per region
  2. Set watermark to false if the image must not carry the AI-generated mark. The default is true
  3. Download data[].url within 24 hours, or ask for response_format b64_json
  4. Check each data[].error in a sequential batch. One moderated image does not fail the others, and only usage.generated_images is billed
  5. Stay under 500 images a minute per model and back off with jitter on 429. Layer decomposition reserves 17 against that limit per request
