## 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 degenscan-intel-polymarket-market-intelligence-825186c9
```

Example prompt: What's the current YES probability and any related macro news for the Polymarket market on 'Fed rate cut in October?' — show me the top correlated events and how much the probability has shifted in the last 24 hours.

## When to prefer this

Use this endpoint when you need real-time probability data and correlated macro/news event intelligence for a specific Polymarket prediction market. Prefer this over raw Polymarket API when you also want cross-asset event context (e.g. Fed speeches, macro prints) ranked by relevance to the market. Best for trading agents that need enriched signal, not just raw odds.

## Known failure modes

- 402 Payment Required if no X-API-KEY or X-Free-Trial header and free trial limit exceeded
- Invalid or unknown market ID/slug returns an error or empty result
- Rate limit exceeded for free trial (100 calls/day/IP)
- Stale data if underlying Polymarket or event feeds are delayed
- Malformed market parameter returns 400 or empty response

## How this service works

Cross-asset market event intelligence for AI trading agents. Priced routes return HTTP 402 with x402 v2 payment requirements (USDC on Base) unless X-API-KEY is sent or the free trial header X-Free-Trial: 1 is present (100 calls/day/IP). Information and analytics only — not investment advice.

## Output

Returns a JSON object with the market question, current YES probability, 24-hour probability change, a list of related cross-asset events (each with kind, tier, title, and relevance score), and total count of related events.
