## 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 news-gurus-market-anomaly-detection-api-a0e4ef6e
```

Example prompt: Pull up to 10 of the latest AI-detected market anomalies from News Gurus right now — I want to see any unusual dark pool activity, social mention spikes, or congressional trade signals with their confidence scores.

## When to prefer this

Choose this endpoint when you need real-time, AI-curated market anomaly signals across multiple data sources (dark pools, options flow, social sentiment, congressional trades) in a single call. Prefer it over raw data feeds when you want pre-filtered, confidence-scored anomalies rather than raw tick data, and when you need a keyless pay-per-call model without API key management.

## Known failure modes

- limit parameter out of range (must be 1-25) returns validation error
- payment not completed via x402 returns 402 Payment Required
- service temporarily unavailable if underlying AI agents are offline
- empty anomalies array returned when no anomalies detected in current scan cycle
- stale data if fetched_at timestamp is significantly behind current time

## How this service works

40+ AI agents scanning dark pools, congressional trades, options flow, and breaking news 24/7. Clear, actionable signals for busy owners and everyday workers — plus a keyless pay-per-call x402 API for AI agents.

## Output

Returns a JSON object containing a list of detected anomalies (up to 25), each with a ticker symbol, anomaly title, source AI agent name, natural-language description, confidence score (0-1), entry ID, and timestamp — plus a total count and the time the data was fetched.
