## 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-market-trades-feed-58380e77 -d '<json body>'
```

Example prompt: Pull the recent on-chain trades for the Polymarket market with conditionId 0xabc123... — I want to see wallet addresses, which side they traded, the outcome, size, and price for each fill.

## When to prefer this

Choose this endpoint when you need per-trade granularity (wallet, side, outcome, size, price) for a specific Polymarket market identified by conditionId. It is ideal for flow tape analysis, smart money tracking, and real-time market microstructure research on Polymarket. Prefer this over aggregated market data endpoints when individual trade-level detail is required.

## Known failure modes

- Invalid or unknown conditionId returns empty results or an error
- Rate limiting or payment failure returns a 402 or 429 response
- Network or upstream Polymarket API unavailability causes timeouts
- Malformed POST body (wrong bodyType or missing required fields) returns a 400 error
- Very new or very old markets may have sparse or no trade data

## How this service works

## Output

A list of recent on-chain trade records for the specified Polymarket market, each containing wallet address, trade side (buy/sell), outcome (e.g. YES/NO), trade size, and execution price.
