## 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 polymarket-recent-trades-whale-flow-by-market-slug-8eb8b26f -d '<json body>'
```

Example prompt: Show me the recent trades on the Polymarket market with slug 'will-trump-win-2024' — only trades over $500 USD — and tell me the net buy/sell flow for Yes and No outcomes plus the biggest orders.

## When to prefer this

Use this endpoint when you need granular, on-chain trade-level data for a specific Polymarket prediction market — especially to track whale activity via minimum USD filters, analyze buy/sell momentum per outcome, or audit wallet behavior. Prefer this over general Polymarket market info endpoints when you need transaction-level detail rather than just prices or odds.

## Known failure modes

- Invalid or unknown market slug returns an error or empty result
- Market has no recent trades — returns empty arrays
- minimo_usd set too high filters out all trades, returning empty lists
- Polymarket API downtime causes upstream data unavailability
- Malformed slug (spaces, wrong format) may return null or error

## How this service works

Recent trades of a Polymarket market (by slug): buys and sells per outcome with price, USD size, wallet and tx, net buy/sell flow per outcome and the largest orders. Set a minimum size to follow whales.

## Output

Returns a JSON object containing: the market slug and question text, a list of recent trades (each with outcome label, buy/sell side, price, USD size, shares, wallet address, transaction hash, and timestamp), a net flow breakdown per outcome (total buys USD, total sells USD, trade count, net USD flow), and a list of the largest orders sorted by size.
