## 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 domain-osint-agentdiet-dev-hackernews-developer-ecosystem-real-time-bcfbbd28 -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and front-page velocity for 'Llama 3'? I want to know how the developer community is reacting to it right now.

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment and discussion velocity from HackerNews — particularly for evaluating how programmers, founders, and tech insiders are reacting to a new framework, startup launch, or AI model. Prefer it over general social media sentiment tools when the target audience is specifically the developer/hacker community rather than mainstream consumers.

## Known failure modes

- Empty or overly generic query returns low-signal results
- Very niche or obscure topics may have sparse HackerNews discussion data
- Rate limits or upstream HackerNews Algolia API downtime may cause failures
- Payment failure via x402 micropayment protocol results in 402 error
- Malformed query string (empty string violates minLength:1 constraint)
