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

## Answer in 30 seconds
POST `/tools/batch_transcripts` on `https://x402vid.com`. Price: **free** per call (x402, Base `eip155:8453`). Best for: RAG ingestion in one free call.

## Copy-paste request
```bash
curl -s -X POST https://x402vid.com/tools/batch_transcripts \
  -H 'Content-Type: application/json' \
  -d '{"video_ids": "VIDEO_ID1, VIDEO_ID2", "max_n": 20}'
# -> HTTP 402 with accepts (payTo, amount in USDC atomic units).
# Sign with your wallet, retry with: -H 'X-PAYMENT: <base64 payload>'
```

## Response shape (deterministic JSON)
Returns up to 20 transcripts + metadata, per-video status, input order. Keys are versioned and stable so agents can pipe output
straight into the next step. Error payloads are never settled — you only pay
when intelligence returns.

## Pipeline pairing
Cheapest path first: prove value with `video_preview` (free) and this endpoint, then graduate upward in the same session. Documented bundles: TopicDesk research ~$0.13, ShortsLab ~$0.07, RivalWatch ~$0.40, LaunchPad ~$1.50. Full machine spec: /skill-packs.json.

## Try free first
- `GET https://x402vid.com/health` — liveness + live per-tool prices
- `POST https://x402vid.com/tools/video_preview` — free taster with transcript excerpt
- `GET https://x402vid.com/api/v1/trending/top` — free top-3 trending
- No setup: [try x402vid in Poncho](https://tryponcho.com/m/x402vid.com) (wallet included)
- Machine docs: [https://x402vid.com/llms.txt](https://x402vid.com/llms.txt) · [https://x402vid.com/openapi.json](https://x402vid.com/openapi.json) · [https://x402vid.com/skill-packs.json](https://x402vid.com/skill-packs.json)
- Directory: [x402scan listing](https://www.x402scan.com/server/788e9347-cf25-4b72-b4c5-624a67549ab2)

## Key Takeaways
- batch_transcripts costs $0.00/call, pay-per-call USDC on Base — no subscription.
- Copy the request above; handle 402 -> sign -> retry with X-PAYMENT.
- Validate free via video_preview before scaling spend.
