## 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-3c2e72e7
```

Example prompt: Pull the full detail for Signalis Pulse narrative ID 4034 — I want to see its current stage, the title, and all the source articles and URLs behind it.

## When to prefer this

Use this endpoint when you have a specific narrative ID (obtained from the Pulse narrative list endpoint) and need full detail: the lifecycle stage, title, and all underlying content items with source attribution. Prefer this over the digest or raw content endpoints when you want structured, narrative-level intelligence about a single tracked AI-business story rather than bulk or historical data.

## Known failure modes

- Invalid or nonexistent narrative ID returns an error or empty result
- Payment failure (insufficient USDC balance) results in HTTP 402 with no content returned
- Narrative ID that has expired or been archived may return a 404 or empty narrative object
- Malformed query parameter format causes a 400 bad request

## How this service works

Signalis synthesizes a 20-source roster into intelligence digests every 4 hours and tracks AI-business narratives with Pulse. Pay-per-call in USDC on Base via x402 — no accounts, no API keys.

## Output

Returns a JSON object confirming the paid call succeeded, along with the narrative's ID, current lifecycle stage (e.g. 'building'), title, and an array of content items each containing a URL, title, and source name (e.g. 'hackernews').
