How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object with the asset name, a stats block containing hit count, hit rate, predicted up/down counts, predictions total, classifiable prediction count, and abs_return_4h_pct percentiles (p75, p95, median), a filter block showing the 30-day lookback window, and an array of recent_samples each with timestamp, hit flag, 4h return, price at prediction, price 4h later, multixsec value, and actual/predicted direction labels.
Example use cases
Validate BTC signal before trading
“Before I act on any signals today, pull the Carbon & Cashmere backtested accuracy stats for BTC over the last 30 days — I need to see the hit rate, how predictions broke down between up and down calls, and a few recent samples showing how the actual price moved versus what was predicted.”
Build ETH signal reliability dashboard
“Grab the Carbon & Cashmere signal accuracy stats for ETH so I can feed them into our reliability dashboard — I want the hit rate, total predictions, the p75 and p95 four-hour return percentiles, and the most recent prediction samples with timestamps and actual versus predicted directions.”
Compare SOL signal accuracy historically
“I'm evaluating whether the Carbon & Cashmere signals for SOL are worth relying on — pull the 30-day backtested stats including the hit count, what percentage of directional calls were correct, and show me a sample of recent predictions so I can see how well the model tracked actual price moves.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/mantis-realized-accuracy/%7Basset%7DWhen to prefer
Use this endpoint when you need to audit or validate the historical accuracy of the Carbon & Cashmere directional signal for a specific crypto asset before acting on it, or when building a signal reliability dashboard. Prefer this over the full bundle endpoint when you specifically need backtested prediction stats and sample-level detail rather than live ML probabilities or regime scoring.
Side effects
- Unknown or unsupported asset symbol returns 404 or empty data
- Asset with insufficient prediction history returns minimal or null stats fields
- Network timeout or service unavailability returns 5xx error
- Payment not processed (x402 protocol failure) results in 402 Payment Required
- Malformed asset path parameter returns 400 Bad Request
