SignalDesk AI – Stats Histogram
x402
SignalDesk AI – Stats Histogram is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).
Computes a frequency histogram over an array of numeric observations, returning binned counts with lower/upper bounds.

How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON array of bin objects, each with a lower bound, upper bound, count of observations in that bin, and a flag indicating whether the upper bound is inclusive. Together the bins cover the full range of input values.
Example use cases
Sensor reading distribution check
“I have 200 temperature readings from my IoT sensors ranging from -10 to 120 degrees. Can you bin them into 20 buckets and tell me how many readings fall in each range?”
A/B test latency analysis
“Here are 500 API response-time samples from my A/B test — split them into 15 bins so I can see where latency clusters.”
Survey score frequency breakdown
“I've got a list of 300 customer satisfaction scores between 1 and 100 — can you divide them into 5 equal bins and show me how many scores land in each group?”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/stats/histogram?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call histogram computation without standing up your own statistics library or data pipeline. It is ideal for ad-hoc distribution analysis on up to 1,000 observations where you want a quick binned view of data spread. Prefer a local library or heavier analytics service if you need weighted histograms, 2D histograms, >1,000 observations, or persistent storage of results.
Side effects
- values array is empty or missing → 400 validation error
- bins parameter outside 1–50 range → 400 validation error
- more than 1000 values submitted → 400 validation error
- values contain non-finite numbers (Infinity, NaN) → validation rejection
- payment not included or insufficient → 402 Payment Required
- worker cold-start or quota exhausted → 503 or timeout
