## 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 ai-tech-startup-news-pulse-feed-with-sentiment-scoring-bfe51a09
```

Example prompt: Pull me the latest AI and startup news with sentiment scores and the overall market pulse — filter it to anything about 'LLM' so I can see how the mood is trending.

## When to prefer this

Choose this endpoint when you need a real-time, sentiment-scored snapshot of AI, tech, or startup news for research or trading signal generation. Prefer it over generic RSS feeds when sentiment scoring and a market pulse aggregate are required in a single call. Best for agents that need to monitor industry mood or route decisions based on market sentiment rather than raw headlines alone.

## Known failure modes

- No matching items if 'topic' filter is too specific or misspelled — returns empty feed
- Stale data if upstream news sources are delayed or unreachable
- Payment failure if x402 USDC micropayment is not processed correctly — returns 402
- Rate limiting if called too frequently in a short window
