Public REST API (GPT Actions and direct HTTP)

First time? Read Start here for curl examples and how this host differs from the paid document service.

There is no /api prefix on this host. All public REST operations for the free tier are under /gpt/v1/. Machine-readable contracts are in the OpenAPI document below.

Endpoints

• GET https://free.officemaker.ai/gpt/v1/instructions — bundled Custom GPT / Actions workflow text (JSON field instructions). Same source as getInstructions in OpenAPI.
• GET https://free.officemaker.ai/gpt/v1/schema — document schema lookup (query documentType, optional format such as markdown).
• GET https://free.officemaker.ai/gpt/v1/gap-analysis — free-tier gap-analysis guidance.
• POST https://free.officemaker.ai/gpt/v1/create-document — create an ad-supported Office file from structured JSON.
• POST https://free.officemaker.ai/gpt/v1/create-preview — previews for an existing created document.
• GET https://free.officemaker.ai/gpt/v1/file?token=… — download files when the create response includes a token-backed URL (documentDownloadUrl / PDF / previews); TTL is given as downloadExpiresIn in the JSON response.

ChatGPT Actions notes

Authentication: none. For POST bodies from ChatGPT Actions, use snake_case property names (document_type, file_name, document_json) or the Actions layer may reject the call. document_json must be a string containing JSON (stringify the document object).
