## 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 quotient-latest-feed-prediction-market-activity-stream-d67b6db0
```

Example prompt: Pull the Quotient latest feed for everything that's changed in the past 2 hours — new probability forecasts, news articles, and X posts across geopolitics, elections, and macro markets.

## When to prefer this

Choose this endpoint when you need a polling feed of all recent Quotient activity across markets rather than intelligence on a specific market. It is ideal for agents that wake on a schedule and need to detect what changed since their last check. Prefer sibling endpoints when you want deep intelligence on specific markets, a single top trade signal, or semantic search across markets.

## Known failure modes

- hours parameter out of range (must be 1–6) returns validation error
- no new activity in the requested window returns an empty feed
- service cold-start latency on Render free tier may cause slow initial response
- invalid types filter value may return empty or error response
- payment failure (x402) if USDC balance is insufficient for $0.016667 per call

## How this service works

Use this chronological feed of new forecasts and newly linked articles/X posts across Quotient-covered Polymarket International, Polymarket US, Kalshi, and Limitless listings. Events include canonical venue routing, response-time venue odds with quote provenance, compact forecast context, and thesis, but omit resolution_pathway; use market detail for full rules context. The complete window avoids per-market fan-out.

## Output

A chronological list of recent Quotient activity items, each including updated probability forecasts with accompanying thesis and resolution pathway, plus newly linked news articles and X/Twitter posts, all scoped to the requested time window and optionally filtered by content type across geopolitics, elections, central bank, conflict, and macro prediction markets.
