ONE Engine Array Frequency Analysis
x402
ONE Engine Array Frequency Analysis is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).
Computes element frequency counts for a JSON array, optionally comparing against a second array or applying offset/size windowing.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns an object mapping each unique element in the input array to its occurrence count, optionally windowed by offset/size and compared against a second array's frequency distribution.
Example use cases
Log error code frequency analysis
“I have a list of up to 1000 HTTP status codes from our server logs — can you count how many times each status code appears so I can see which errors are most common?”
Compare tag frequencies across two datasets
“I have two arrays of product tags from two different categories. Can you compute the frequency of each tag in the first array and compare it against the second array's tag frequencies?”
Survey response tallying
“Here are 500 survey answers in an array — each is one of 'Agree', 'Disagree', or 'Neutral'. Count how many times each response appears so I can tally the results.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/frequency/t6?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, cheap ($0.004 per call) pay-per-use frequency count on a JSON array of up to 1000 elements, especially within an autonomous agent workflow on Base using x402 micropayments, without needing to spin up local computation or a heavier data pipeline.
Side effects
- Array exceeds 1000 items — request rejected or truncated
- Invalid JSON array format in 'values' field returns an error
- Non-serializable array elements may cause parsing failures
- Payment not provided or insufficient USDC balance triggers 402 response
- Empty array input may return empty frequency map
