## 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 hn-pulse-agentdiet-dev-hackernews-developer-ecosystem-real-time-03e48ab5
```

Example prompt: What's the live HackerNews developer sentiment around 'Anthropic Claude' right now — how fast is it trending on the front page and what are developers saying?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment from HackerNews rather than general social media sentiment. It is particularly suited for YC startup launch monitoring, framework adoption research, and AI model reception tracking within the technical developer ecosystem, where HackerNews is the primary signal source.

## Known failure modes

- Empty or missing query parameter returns validation error
- Query returns no results if topic has no recent HackerNews coverage
- HackerNews API rate limits or downtime may cause degraded or empty responses
- Very niche or misspelled keywords may return low-confidence or empty sentiment data
- Payment failure via x402 results in 402 response before data is returned
