How this service works
HALOWERK marktwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns a structured order book for the requested trading pair and exchange, containing bid and ask price levels (up to the requested number of levels), optionally aggregated into price bands of the specified width in basis points. May include metadata such as the effective cap on levels used by the venue.
Example use cases
Arbitrage opportunity detection
“Fetch the top 50 levels of the ETH/USDT order book from both Binance and Kraken so I can compare prices and spot any arbitrage gaps.”
Market depth analysis before large trade
“I'm about to buy a large amount of BTC — can you get me the BTC/USDC order book from Binance with 500 levels per side so I can estimate market impact?”
Grouped book for trading dashboard
“Get the SOL/USDC order book from OKX with 100 levels per side, grouped into 20 bps bands, so I can display a clean depth chart on my dashboard.”
Technical details
Endpoint
POSThttps://markt.netzhandwerker.de/orderbookWhen to prefer
Use this endpoint when you need real-time order book depth data from a specific centralized exchange (Binance, Coinbase, Kraken, OKX, or Bybit) without managing individual exchange API keys. Prefer it over direct exchange integrations when you want a unified interface across multiple venues, or when you need price-level grouping built in. Pay-per-call via x402/USDC makes it suitable for low-frequency queries where a subscription would be overkill.
Side effects
- Unsupported trading pair for the selected venue returns an error
- Requested levels exceed the venue's maximum cap (capped automatically or returns error)
- Exchange API unavailability causes a timeout or upstream error
- Invalid symbol format (not matching BASE/QUOTE pattern) returns a validation error
- group_bps outside valid range (0.1–500) returns a validation error
