## 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 scanna-recent-trades-b8976dea
```

Example prompt: Pull the 100 most recent trades for Polymarket condition ID 0xabc123def456... and page through them so I can see who's been buying and selling and whether any whale trades have come in.

## When to prefer this

Use this endpoint when you need a paginated, time-ordered feed of individual trades for a specific Polymarket condition ID — especially when you need to detect whale activity, paginate through high-volume trade history, or filter trades since a specific unix timestamp. Prefer this over aggregate endpoints when you need raw per-trade granularity rather than summary statistics.

## Known failure modes

- 400 if market_id is absent
- 400 if cursor is malformed (never silently ignored)
- 503 with 'trades_cold_storage' error for archived markets
- Degraded empty 200 if the archive probe itself errors
- Empty billable 200 for markets with no trades

## How this service works

Recent trades for one market from the post-cutover trades_v2 table, newest first, keyset cursor. timestamp is whole unix seconds and the cursor is {ts,id}; the query sorts on that same floored key, so trades sharing a second page exactly once. id is a JSON number. An archived market returns 503 trades_cold_storage - unless the archive probe itself errors, which degrades to an empty 200. A market with no trades is an empty, billable 200.

## Output

Returns a JSON object with a list of trades (each containing id, condition_id, proxy_wallet, price, size, side, notional, timestamp, and is_whale), a count of returned trades, and an optional next_cursor string for keyset pagination. Returns an empty list with count 0 for markets with no trades. Returns 503 for archived markets stored in cold storage.
