How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object with the coin symbol (ETH), spread in basis points (spread_bps), ask wall ratio (ask_wall_ratio), bid wall ratio (bid_wall_ratio), and bid-ask imbalance score — providing a snapshot of ETH orderbook microstructure at the time of the call.
Example use cases
Example prompt
“What does the ETH orderbook look like right now — specifically the spread in basis points, how big the bid and ask walls are relative to each other, and whether there's a significant bid-ask imbalance?”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/orderbook/ETHWhen to prefer
Use this endpoint when you need real-time ETH-specific orderbook microstructure metrics such as spread, wall ratios, and imbalance — particularly for short-term trading signal generation, market depth monitoring, or detecting large buy/sell pressure events. Prefer this over generic price APIs when orderbook structure (not just price) is needed.
Side effects
- ETH orderbook data unavailable or exchange feed down — may return error or stale data
- Rate limit exceeded if too many calls in rapid succession
- Malformed response if upstream liquidity source is temporarily unreachable
- Invalid coin path returns 404 or empty response
