ChatGPT

Build the GPT

1. In ChatGPT, click your profile → My GPTs → Create a GPT.
2. In the Configure tab, scroll to Actions → click Create new action.
3. Under Schema, click Import from URL and paste:

https://steadyshot.ai/openapi.json

1. Under Authentication, choose API Key → Bearer. Paste an API key from /api-keys.
2. Add this to the GPT’s instructions so it picks tools correctly:

You can call SteadyShot to generate consistent character
illustrations. When the user asks to "make an image of [character]
doing [thing]", call list_characters first if you don't know the
character_id, then generate_scene with the matched id and the user's
prompt. For variations of an existing scene, use vary_scene with the
returned image_id. Storybooks: generate_storybook with an array of
page prompts.

Try it

• “Show me my SteadyShot characters” → GPT calls list_characters.
• “Generate Luna reading by a campfire” → GPT looks up Luna’s id, then calls generate_scene. Inline image preview.
• “Now make 4 versions where she’s frowning” → GPT calls vary_scene with the last image_id.
