How this service works
Queries public crypto exchanges for one trading pair and returns each venue separately with its last price, bid, ask, spread in basis points, 24-hour high, low and volume, and the age of the value in milliseconds. On top of the raw quotes it computes what a single venue cannot tell you: the median across venues, the spread between the cheapest and dearest venue in basis points, and which venue is the outlier.
Output
A structured response containing one record per exchange venue with: last traded price, best bid, best ask, spread in basis points, 24-hour high and low, 24-hour volume, and the age of the data in milliseconds. Additionally includes cross-venue computed fields: the median price across all venues, the spread between the cheapest and most expensive venue in basis points, and identification of the outlier venue.
Example use cases
Arbitrage opportunity scanner
“Check the ETH/USDC price right now across every exchange and tell me which venues have the biggest spread between them in basis points — I want to know if there's an arbitrage opportunity.”
Best execution venue selection
“I'm about to buy SOL/USDT — can you pull the current quotes from all exchanges and tell me which venue has the lowest ask price and tightest spread so I know where to execute?”
Price outlier alert
“Fetch the current BTC/USD snapshot across all venues and flag any exchange that's quoting a price significantly off the median — I need to know if any venue is showing a suspicious outlier.”
Technical details
Endpoint
POSThttps://finanz.halowerk.com/v1/quote-snapshot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a multi-venue aggregated view of a crypto trading pair rather than a single exchange's data. It is especially useful for price discovery, cross-venue arbitrage detection, best execution analysis, or detecting price manipulation/outliers. Prefer it over single-exchange APIs when you need the median price or inter-venue spread as computed metrics.
Side effects
- Unknown or unsupported trading pair returns an error or empty venue list
- Exchange APIs temporarily unavailable may result in missing or stale data for specific venues
- Very illiquid pairs may return zero volume or missing bid/ask on some venues
- Network timeout if exchange APIs are slow, resulting in partial results
- Invalid pair format (e.g. wrong delimiter or casing) may cause a 400 error
