## 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 agentdiet-dev-hackernews-developer-ecosystem-real-time-sentiment-pulse-95200b51 -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews about Anthropic's Claude — are there active discussions trending right now?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — the gold standard for technical and startup ecosystem opinion. Prefer this over general web search when you want front-page velocity, community scoring, and the authentic developer voice rather than media coverage. Ideal for evaluating frameworks, monitoring startup buzz, or gauging reaction to AI model launches within the technical community.

## Known failure modes

- Empty or overly generic query returns low-relevance results
- Topic too niche to have recent HackerNews coverage returns sparse data
- Payment failure via x402 prevents endpoint execution
- Rate limiting if called excessively without idempotency key on retries
- HackerNews API upstream downtime may cause degraded or empty responses
