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.
Example use cases
Aggressor-side analysis for algo trading
“Fetch the last 500 trades for BTC/USDT on Binance and tell me the aggressor side for each one — I need the raw tape, no smoothing.”
Cross-exchange trade comparison
“Get me the 100 most recent trades for SOL/USDC from both Kraken and OKX so I can compare the prints side by side.”
Time-window tick data extraction
“Retrieve all public trades for ETH/USDT on Bybit starting from 2024-06-01T12:00:00Z up to the most recent 60 — I need price, quantity, and timestamp for each.”
Technical details
Endpoint
POSThttps://markt.halowerk.com/tradesWhen to prefer
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.
Side effects
- 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
