Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability chiro-x402-chiropractic-knowledge-retrieval-afcebb21
```

Example prompt: Pull the transcript for chiropractic video '1. Tour of the Website' from the Chiro x402 knowledge base — it's in the New Member Onboarding section and I need the full text content.

## When to prefer this

Choose this endpoint when you need to retrieve the full text of a specific chiropractic training video transcript by its known video ID. It is best suited for agents that have already identified a target video ID (e.g. from a prior search or index) and need the raw transcript content. It is not a search endpoint — use it for direct document retrieval, not discovery across the corpus.

## Known failure modes

- Invalid or unknown video_id returns no matching transcript
- Payment failure via x402 protocol results in 402 response and no content delivered
- Malformed video_id string may cause lookup failure
- Network or Base mainnet payment confirmation delay may cause timeout
- Transcript file not found for valid-looking IDs that don't exist in corpus

## How this service works

Paid AI-agent endpoint for searching 500K+ segments of general chiropractic knowledge. $0.05 USDC per query on Base mainnet. No API keys, no accounts — agents pay via x402 v2 protocol and receive structured results.

**Corpus:** Clinical protocols, wellness plans, marketing strategies, patient communication, practice management — sourced from general chiropractic training.

## Output

Returns a structured object containing the video transcript text, the video ID, file size in bytes, the transcript file path within the corpus (indicating category and module), and payment confirmation details including token type, amount, and network.
