## 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 truth-bear-shadow-chatter-ae627303
```

Example prompt: Pull the latest 48-hour public channel chatter about 'NVIDIA earnings' — I want all the raw messages with their platform, source URL, timestamps, and the LLM trend summary with the echo-chamber concentration index.

## When to prefer this

Use this endpoint when you need a rapid, sourced snapshot of raw public-channel discourse on any topic within the last 48 hours, especially when you also want a built-in echo-chamber concentration signal and verifiable per-message hashes. Prefer it over general web search when you want structured social chatter data with provenance metadata rather than curated news or fact-checked content. It is explicitly not for verified facts, official sources, or forecasting.

## Known failure modes

- 422 no_charge — no messages found for the topic in the 48-hour window; not billed
- topic parameter missing or malformed — likely 400 error
- LLM summary non-reproducible — only per-item grey_ref hashes are verifiable offline
- stale or incomplete public channel coverage if source scraping is partial
- echo-chamber index may be misleading for niche or low-volume topics

## How this service works

Pay-per-call, hash-verifiable environmental data for AI agents via x402 (USDC on Base, no API key). Flood-risk & river-anomaly check: real-time US river water level (gage height), streamflow, flood stage vs official USGS/NOAA thresholds + 5-year seasonal statistical anomaly + record_hash verifiability. Plus air quality (US AQI/PM2.5) and precipitation (rainfall/drought).

## Output

A list of raw public messages each containing the platform name, source URL, timestamp, message text, and a sha256-based grey_ref for verification; plus an LLM-generated trend summary of the topic's narrative and an echo-chamber concentration index indicating how homogeneous the discourse is. Returns a 422 no_charge error if no messages exist in the 48-hour window.
