## 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 halowerk-marktwerk-raw-trade-tape-545131f1 -d '<json body>'
```

Example prompt: Pull the last 200 raw trades for ETH/USDC on Coinbase — I want each print exactly as the exchange reported it, including which side was the aggressor.

## When to prefer this

Choose this endpoint when you need unmodified, per-print trade data exactly as a specific exchange publishes it — including aggressor-side attribution and the provenance of that attribution. Prefer it over aggregated or consolidated feeds when the goal is tick-level analysis, reconstructing order flow, or validating execution quality on a particular venue. It is especially valuable when aggressor-side accuracy matters (e.g. distinguishing maker vs taker flow) and you need to know whether the side was natively reported or derived.

## Known failure modes

- Invalid or unsupported BASE/QUOTE symbol format — exchange may not list the pair
- Venue not recognized — must be one of binance, coinbase, kraken, okx, bybit
- Limit exceeds maximum of 1000 (or 60 for Bybit spot)
- since timestamp outside the exchange's published history window — returns empty or partial results
- Exchange API unavailable or rate-limited — upstream timeout or error propagated
- Payment failure — x402 micropayment not processed, request rejected

## How this service works

Returns the raw public trade tape of Binance, Coinbase, Kraken, OKX or Bybit for one BASE/QUOTE pair, oldest first, exactly as the exchange reports it — no smoothing, no merging of prints. side is the side of the aggressor: reported directly by Kraken, OKX and Bybit, derived from the maker flag at Binance, and inverted from the maker side at Coinbase; side_source names which case applies. Where an exchange does not publish it, side is "unbekannt" and side_inferred stays false rather than guessin

## Output

An ordered list (oldest first) of raw trade records for the requested pair and exchange, each containing price, quantity, timestamp, aggressor side (or 'unbekannt' if unknown), a side_source label indicating how the side was determined, and a side_inferred boolean indicating whether the side was derived rather than natively published.
