gpt-simple-generator

A tiny PHP 8+ API for generating text-only, evidence-summarizing articles using the OpenAI Responses API (Structured Outputs / JSON mode) with optional PubMed grounding.
No frameworks — just clean PHP + Composer — ready for Nginx/Apache or PHP’s built-in server.

---

Features

• Plain PHP (no framework), small footprint
• OpenAI Responses API:
  • Sends content blocks with type: "input_text"
  • Sets output format via text.format (json_schema first; auto-fallback to json_object)
• PubMed context (optional) with simple caching in storage/cache/
• Bearer auth: Authorization: Bearer <API_KEY>
• Structured outputs backed by JSON Schemas in schema/
• Logging to storage/logs/app.log
• Zero images: text-only articles

---

Requirements

• PHP 8.2+ (tested on 8.4) with curl and json extensions
• Composer
• Web server (Nginx/Apache) or PHP’s built-in server
• OpenAI API key with access to the Responses API and your chosen model(s)
