## 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 x402-audit-agentdiet-dev-hackernews-developer-ecosystem-real-time-40a08db6
```

Example prompt: What's the current HackerNews sentiment and front-page velocity around 'Anthropic Claude' — pull live developer discussions and community reaction right now.

## When to prefer this

Use this endpoint when you need real-time developer community sentiment specifically from HackerNews — ideal for tracking YC startup launches, evaluating framework adoption momentum, assessing community reception of a new AI model, or gauging front-page velocity of a tech topic. Prefer this over general web search when the goal is developer-specific opinion rather than broad media coverage.

## Known failure modes

- Empty or generic query string returns no meaningful results
- HackerNews API rate limits or downtime cause data gaps
- Very niche or misspelled keywords yield zero matching threads
- Sentiment signal may be sparse for very new or obscure topics
- Payment failure (402) if x402 USDC balance is insufficient
