## 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 workflows-agentdiet-dev-hackernews-developer-ecosystem-real-time-48a67398
```

Example prompt: What's the live HackerNews sentiment and discussion velocity around 'LangChain' right now — are developers excited or skeptical?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment from HackerNews rather than broad social media sentiment. It is ideal for tracking YC startup launches, open-source library reception, AI model buzz, and framework adoption trends among technical audiences. Prefer this over Twitter/X or Reddit sentiment tools when the target audience is specifically the HN developer and founder community.

## Known failure modes

- Empty or very niche query returns no HN discussions — low or null results with minimal signal
- HackerNews API rate limits or downtime causing upstream fetch failures
- Overly broad queries (e.g. 'AI') may return noisy, unactionable results
- Query keyword typo or misspelling yields irrelevant threads
- Endpoint returns a generic object schema — malformed or sparse response possible if upstream data is thin
