How this service works
Count values in equal-width histogram bins with progressively richer numeric statistics. Tier 8/10 standard bundle with 8 output feature sets.
Output
Returns histogram bin edges, per-bin value counts, and up to 8 progressively richer numeric statistical feature sets characterizing the input distribution — including measures such as mean, median, variance, skewness, kurtosis, percentiles, and other distributional summaries depending on the tier.
Example use cases
Analyzing sensor reading distribution
“I have a list of temperature sensor readings from the past week and I want to see how they're distributed — can you put them into equal-width histogram bins and give me all the statistical detail you can, including counts per bin and summary stats?”
Grading distribution for exam scores
“Here are the exam scores for my 30 students: [55, 62, 71, 48, 90, 83, 77, 69, 58, 74, 88, 61, 79, 52, 95, 66, 73, 84, 57, 91, 68, 76, 85, 63, 70, 81, 59, 78, 87, 64]. Can you bin them into equal-width ranges and tell me how many students fall in each bin, along with rich distribution statistics?”
E-commerce price range frequency analysis
“I've got a dataset of 50 product prices from our catalog and I want to understand how prices are clustered — please compute equal-width histogram bins, count how many products land in each bin, and give me the full numeric statistics breakdown.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/histogram/t8?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both histogram bin counts AND rich multi-layer numeric statistics in a single call at low cost ($0.01 USDC). The Tier 8 bundle provides 8 output feature sets, making it ideal when you want more than just raw counts — covering distributional shape, central tendency, and spread in one response. Prefer over simpler histogram APIs when downstream analysis requires percentiles, skewness, or kurtosis alongside frequency data.
Side effects
- Empty or null input array returns an error or empty histogram
- Non-numeric values in the array cause a validation or parsing error
- Insufficient data points to form meaningful bins may produce degenerate output
- Payment failure via x402 returns a 402 Payment Required response
- Malformed request body returns a 400 Bad Request
- Extreme outliers may produce very sparse bins with most counts at zero
