## 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 polymarket-odds-agentdiet-dev-hackernews-developer-sentiment-pulse-af961233

Example prompt: What's the current HackerNews developer sentiment around LangChain — are people excited about it or is there backlash in the discussions?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical forum for developers, founders, and tech enthusiasts. Prefer this over general web sentiment tools when the audience is technical developers or startup founders, or when you want front-page velocity as a signal of trending interest rather than just social media volume.

## Known failure modes

- Empty or very niche query keyword returns no matching HackerNews threads
- HackerNews API rate limits or downtime cause failed or stale responses
- Ambiguous keywords (e.g. common English words) return irrelevant discussions
- Payment failure via x402 results in 402 response with no data
