## 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 prediction-market-trades-feed-7738314b
```

Example prompt: Pull the last 50 trades for the Polymarket market with slug 'will-bitcoin-reach-100k-in-2025' and give me the buy/sell breakdown, size-weighted average price, last traded price, and price range.

## When to prefer this

Choose this endpoint when you need recent trade-level data or derived trading statistics (volume, price, counts) for a specific Polymarket prediction market, identified by conditionId, slug, or numeric ID. Prefer this over order book endpoints when you need historical fill data rather than open orders, and over market-list endpoints when you already know which market you want.

## Known failure modes

- Invalid or unresolvable market identifier returns an error or empty result
- Market slug or numeric ID that cannot be mapped to a conditionId causes resolution failure
- Requesting limit above 100 is rejected by schema validation
- min_size filter too high returns empty trade list
- Venue other than 'polymarket' is not currently supported and will be rejected
- Network or upstream data source unavailability may cause timeout or 5xx error

## How this service works

Recent trades for one prediction market (by conditionId, slug or numeric id): a PII-stripped pseudonymous feed plus a derived summary — trade count, buy/sell volume and counts, size-weighted average price, last price and range.

## Output

Returns a pseudonymous list of recent trades (up to 100, default 25) for the specified prediction market, each stripped of PII, plus a derived summary including total trade count, buy and sell volume and counts, size-weighted average price, last trade price, and high/low price range.
