## Question
Cheapest-path-first bundles: entry funnel to premium in one session.

## Answer in 30 seconds
POST `/tools/transcript_markdown` on `https://x402vid.com`. Price: **free** per call (x402, Base `eip155:8453`). Best for: saving research dossiers agents share.

## Copy-paste request
```bash
curl -s -X POST https://x402vid.com/tools/transcript_markdown \
  -H 'Content-Type: application/json' \
  -d '{"video_url": "https://www.youtube.com/watch?v=VIDEO_ID"}'
```

Returns 200 directly — no payment header, no wallet. Graduate anytime: paid calls start at $0.01 (`search_and_rank_videos`).

## Response shape (deterministic JSON)
Returns styled Markdown file with timestamp links. Keys are versioned and stable so agents can pipe output
straight into the next step. Error payloads return error JSON — nothing to settle, calls are free.
