## 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-6872e523
```

Example prompt: What's the current HackerNews sentiment and front-page velocity for 'Rust' — are developers reacting positively or negatively in live discussions right now?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical forum for developer discourse and startup launches. Ideal for gauging YC startup reception, open-source library momentum, AI model buzz, or framework adoption trends among technical audiences. Prefer this over general social media sentiment tools when the target audience is specifically developers and the signal source should be HackerNews front-page and comment velocity.

## Known failure modes

- Empty or too-generic query returns low-signal or no results
- HackerNews API rate limits or downtime cause fetch failures
- Very niche or obscure topics may have insufficient discussion volume for meaningful sentiment
- Payment via x402 not completed results in 402 response blocking the call
- Misspelled or ambiguous keyword may match unintended discussions
