## 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 company-enrich-agentdiet-dev-hackernews-developer-ecosystem-real-time-9a10d52d

Example prompt: What's the live HackerNews developer sentiment on Rust right now — is it trending positively or negatively, 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 canonical forum for developer and startup discourse. Prefer this over general social media sentiment tools when your audience is technical, and when you need front-page velocity signals alongside sentiment. Ideal for evaluating how a new framework, AI model, or startup is being received by the developer ecosystem in real time.

## Known failure modes

- Missing or empty query parameter returns validation error
- Query term with no HackerNews presence may return empty or low-confidence results
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not processed
- Service may return stale data if HackerNews API is temporarily unavailable
- Overly broad query terms may return noisy or low-quality sentiment signals
