## 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 social-momentum-intelligence-cross-platform-topic-tracker-5fa2e9aa
```

Example prompt: Pull the social momentum for 'LLM agents' across Hacker News, GitHub, and Reddit over the past 48 hours — show me up to 15 stories from each platform and restrict Reddit to the MachineLearning and artificial subreddits.

## When to prefer this

Use this endpoint when you need a multi-platform, real-time snapshot of developer and community interest around a specific topic, keyword, or entity — especially when comparing momentum across HN (tech commentary), GitHub (code activity), and Reddit (broad community discussion) simultaneously. Prefer this over single-platform scrapers when cross-community signal is important, or when you need configurable time windows (1–168 hours) to compare short-term spikes vs. sustained interest. Ideal for research agents, trend-monitoring pipelines, and competitive intelligence tasks that require no API keys and can pay per-call in USDC.

## Known failure modes

- Missing required 'topic' query parameter returns 400 error
- window_hours outside 1–168 range returns validation error
- reddit_subreddits array exceeding 5 items rejected
- Platform API rate limits or downtime may yield partial results for one source
- Very niche topics may return empty or sparse results
- Payment of 0.008 USDC on Base mainnet required; unpaid requests return HTTP 402

## How this service works

Cross-platform social momentum for any topic. Queries Reddit (recent top posts), Hacker News (recent stories), and GitHub (active repos) in parallel and returns a composite momentum score (0–100) plus raw results from each platform. Single call replaces three separate searches. Use before committing to research, writing, or trading: 'is this topic gaining traction right now?' No API keys required.

## Output

Returns ranked lists of Hacker News stories, GitHub repositories, and Reddit posts related to the queried topic within the specified lookback window, with engagement signals (upvotes, comments, stars, etc.) that indicate momentum and community interest.
