## 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 email-verify-agentdiet-dev-hackernews-developer-ecosystem-real-time-b7ae223a
```

Example prompt: What's the current developer sentiment on HackerNews for 'Mistral AI' — are people excited, skeptical, or critical, and how fast is it moving on the front page?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the primary forum for startup founders, engineers, and early adopters. Prefer it over general social sentiment APIs when the audience is technical/developer-focused, or when tracking YC startup launches, framework adoption, or AI model reception among practitioners.

## Known failure modes

- Empty or whitespace query returns validation error
- Very obscure keywords with no HackerNews presence may return empty or low-confidence results
- HackerNews API rate limits or downtime may cause upstream failures
- Payment not processed (HTTP 402) blocks the response
- Ambiguous keywords may return mixed sentiment across unrelated topics
