## 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 signalis-pulse-narrative-detail-60f32332
```

Example prompt: Pull the full Pulse narrative detail for narrative id 'narr_abc123' — I want to see all the content items, which sources are driving it, and what lifecycle stage it's in right now.

## When to prefer this

Use this endpoint when you have a specific narrative id (e.g. obtained from the active narratives listing endpoint) and need the full detail — content items, sources, and lifecycle updates — for that single narrative. Prefer over the digest endpoints when you need granular per-narrative data rather than a broad historical summary.

## Known failure modes

- Invalid or unknown narrative id returns a 404 or empty result
- Pulse service unavailable results in no charge and an error response
- Malformed id parameter causes a 400 bad request
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

Paid ($0.01 USDC via x402). Narrative detail: content items, source attribution, and lifecycle updates for one narrative. Proxied from the Pulse service. Compute-first / settle-after — you are never charged when Pulse is unavailable or returns an error.

## Output

Returns structured detail for a single narrative: the list of content items associated with it, source attribution data, and lifecycle stage/status updates as tracked by the Pulse service.
