Delx Median is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Computes the median of a list of numbers, providing a robust central tendency measure that is unaffected by outliers.

How this service works
Median of numbers. Use for robust central tendency when outliers pollute averages. Returns the median of the provided numeric list. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
Returns the median value of the provided numeric array as deterministic first-party JSON. The median is the middle value when numbers are sorted — or the average of the two middle values for even-length arrays — making it robust against extreme outliers.
Example use cases
Robust salary benchmarking
“I have a list of salaries from our survey — 42000, 48000, 51000, 53000, 250000, 47000, 49000 — and the CEO salary is skewing things. Can you give me the median so I get a realistic picture of what most employees earn?”
Median sensor reading from IoT data
“My temperature sensors logged these readings over the last hour: 22.1, 22.4, 22.3, 99.9, 22.2, 22.5, 22.0 — one sensor clearly glitched. Give me the median so the spike doesn't mess up my baseline.”
Price analysis for market research
“Here are the prices I scraped for the same product across 10 different sites: 19.99, 21.50, 20.00, 18.75, 145.00, 19.50, 21.00, 20.25, 19.99, 22.00. What's the median price so I can ignore the obvious outlier?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/medianWhen to prefer
Choose this endpoint when you need a robust central tendency measure and your data may contain outliers or skewed distributions that would distort a simple mean. Prefer this over a mean calculation when data includes anomalies, extreme values, or long-tail distributions such as incomes, prices, or sensor readings. It is also ideal when you need a guaranteed deterministic result without any external API key or subscription overhead.
Side effects
- Empty array or missing 'values' field returns a structured validation error (not billed)
- Array exceeding 10,000 items is rejected
- Non-numeric values in the array cause a validation error
- Payment failure or insufficient USDC balance blocks the call
