## 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 agentdiet-dev-hackernews-developer-ecosystem-real-time-sentiment-pulse-3d36f115

Example prompt: What's the current HackerNews sentiment and front-page velocity for 'Anthropic Claude' — are developers buzzing positively or negatively about it right now?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the primary forum where early adopters, engineers, and startup founders discuss technology. Prefer this over general social media sentiment tools when your audience is the developer/hacker ecosystem, or when you need front-page velocity as a signal of technical community excitement.

## Known failure modes

- Empty or too-generic query returns no meaningful signal
- HackerNews API rate limits or downtime cause degraded results
- Very niche or obscure topics may return sparse discussion data
- Query terms with multiple meanings may aggregate unrelated discussions
- Payment failure via x402 returns 402 error before processing
