How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
Returns a JSON object containing the coin symbol, trade side, USD amount, depth metrics (mid price, spread percentage, available depth in USD, trade size as percentage of depth), estimated impact (severity label such as 'minimal', estimated slippage percentage, model note), and a human-readable AI summary with a verdict on whether to execute immediately or split the order.
Example use cases
Pre-trade slippage check for ETH
“I'm about to sell $80,000 worth of ETH — can you estimate how much slippage I should expect and whether I'd be better off splitting this into smaller orders?”
SOL liquidity depth assessment
“How deep is the SOL order book right now? I want to know if a $150,000 buy would move the market significantly before I pull the trigger.”
DOGE large order impact analysis
“Would buying $25,000 of DOGE cause noticeable price impact, or is there enough liquidity to absorb an order that size without much slippage?”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/ai/price-impact/%7Bcoin%7DWhen to prefer
Use this endpoint when an agent or user needs to pre-trade assess market impact before placing a large crypto order — especially when order size relative to available liquidity is unknown. It is preferable to a generic price feed when the question is not just 'what is the price' but 'what will happen to the price if I trade this size'. Best suited for trades where slippage and depth matter, not for small retail trades.
Side effects
- Unsupported or unrecognized coin symbol returns an error or empty result
- Missing required usd query parameter may return a 400 or default behavior
- Stale or unavailable depth data may produce low-confidence estimates
- Payment failure (x402) blocks access if USDC payment not processed
- Very illiquid coins may return high-uncertainty estimates with wide confidence bands
