How this service works
Machine-readable settlement service
Output
A JSON object containing basic descriptive statistics computed over the input array, typically including measures such as mean, median, mode, min, max, count, range, variance, and standard deviation.
Example use cases
Summarize sensor readings dataset
“I have a batch of temperature sensor readings — [22.1, 23.5, 21.8, 24.0, 22.7, 23.1] — can you calculate the basic stats like mean, min, max, and standard deviation for me?”
Check score distribution for a quiz
“Here are the quiz scores from my class: [85, 90, 72, 88, 95, 60, 78, 82, 91, 67]. Can you compute the basic descriptive statistics so I can see how they're distributed?”
Validate financial data spread
“I've got these monthly revenue figures in thousands: [120, 135, 98, 142, 110, 127, 155, 103]. Can you run basic statistics on them so I can see the average, variance, and range?”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/number.stats--basic-statisticsWhen to prefer
Choose this endpoint when you need a quick, pay-per-call computation of basic descriptive statistics on a numeric array without setting up a local statistics library or data science environment. Especially useful in agent pipelines where numeric summaries are needed on demand at low cost ($0.001/call).
Side effects
- Empty or missing input array returns validation error
- Non-numeric values in array may cause computation error or be silently ignored
- Payment failure (402) if USDC payment header is missing or insufficient
- Malformed request body returns 400 error
- Very large arrays may time out depending on hosting limits
