## 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-narratives-457cf6ca
```

Example prompt: What are the active AI-business narratives right now — I want to see their lifecycle stages and which sources are driving momentum.

## When to prefer this

Use this endpoint when you need a real-time, curated view of active AI-business narratives with lifecycle and momentum metadata — particularly when you want to understand not just what topics are trending but where they are in their narrative arc and what is driving them. Prefer this over generic news or trend APIs when the focus is specifically on AI-business storytelling with structured lifecycle context.

## Known failure modes

- Pulse service unavailable — no charge applied, returns error indicating upstream unavailability
- Invalid or malformed query parameters — returns 400 bad request
- Authentication or payment failure via x402 — returns 402 Payment Required
- Rate limiting or quota exceeded — returns 429 Too Many Requests
- No active narratives found — returns empty list or 404

## How this service works

Paid ($0.01 USDC via x402). Active AI-business narratives with lifecycle stage, driving sources, and momentum. Proxied from the Pulse service. Compute-first / settle-after — you are never charged when Pulse is unavailable or returns an error.

## Output

A list of active AI-business narratives, each with its current lifecycle stage (e.g. emerging, growing, peaking, declining), the sources driving it, and a momentum score or indicator — sourced from the Pulse service.
