How this service works
PPTX to Markdown: Convert a PPTX (PowerPoint) presentation to Markdown. Provide a direct URL or base64-encoded file bytes. Each slide becomes a heading with its text content — pitch decks and slide reports become LLM-readable text. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/pptx_to_markdown.
Output
A JSON response containing a 'result' object with the full Markdown text of the presentation, where each slide is represented as a heading followed by its text content, optionally truncated to the specified max_length.
Example use cases
Pitch deck analysis for AI agent
“I have a startup pitch deck at https://example.com/pitch.pptx — can you convert it to Markdown so I can analyze the content and summarize the key slides?”
Slide report ingestion pipeline
“Convert this quarterly report PowerPoint at https://reports.example.com/q4-2024.pptx into Markdown text so I can feed it into my LLM pipeline. Limit the output to 80000 characters.”
Meeting deck text extraction
“I've got a PPTX file I want to search through — here it is as a base64 string. Convert it to Markdown so I can find the slides that mention pricing.”
Technical details
Endpoint
POSThttps://x402.freeq.one/tools/pptx_to_markdown?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract readable text from a PowerPoint presentation for LLM processing, summarization, or search — especially for pitch decks, slide reports, or meeting decks. Prefer this over generic document extractors when the input is specifically a .pptx file and slide-by-slide structure is useful.
Side effects
- Invalid or inaccessible URL returns an error
- Malformed base64 input causes a parse failure
- File too large (base64 exceeds 28MB limit) is rejected
- Non-PPTX file format may fail to parse
- Network timeout fetching remote URL
- Payment not included or insufficient USDC causes 402 response
