## 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 x402stock-trending-stocks-market-sentiment-fa6a8d5f
```

Example prompt: What stocks are trending most on Reddit and 4chan right now, and what's the overall market fear/greed sentiment?

## When to prefer this

Use this endpoint when you need a real-time snapshot of which stocks retail investors are actively discussing across Reddit and 4chan /biz/, along with a blended attention score and fear/greed context. Ideal for meme-stock detection, social momentum signals, or gauging retail sentiment without needing historical data or specific ticker lookups. Prefer this over individual ticker endpoints when you want a market-wide trending leaderboard rather than data on a known stock.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 with payment details
- Upstream Reddit or 4chan data unavailable — section status may show 'error' instead of 'ok'
- Stale data if crawl pipeline is delayed — check as_of timestamp
- Invalid or missing x402 payment header — request rejected before processing

## How this service works

Use for one call answering 'where is retail attention right now': a deterministic 0–100 attention score per ticker blending Reddit finance-community and 4chan /biz/ mention shares (24h window), with momentum, cross-platform confirmation, breadth & concentration (HHI), and Fear & Greed context. Transparent — every row carries its raw per-platform inputs. From x402stock

## Output

A JSON object containing a ranked list of top trending tickers over the past 24 hours, each with an attention score (0-100), Reddit and 4chan mention counts and percent changes, cross-platform flag, momentum percentage, and mention share. Also includes market breadth stats (total mentions, HHI concentration), a fear/greed score with rating, section health indicators, and the scoring methodology.
