x402
ONE Engine Array Frequency (T1) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).
Computes the frequency distribution of elements in a JSON array, with optional comparison against a second array.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
An object containing frequency counts for each unique value found in the input array, showing how many times each element appears. When a comparison array is provided, the result may include frequency data for both arrays for side-by-side analysis.
Example use cases
Survey response tally
“I have survey responses in this array: ["agree","disagree","strongly agree","agree","neutral","agree","disagree"] — count how many times each answer appears so I can see the breakdown.”
Log error code frequency
“Here's an array of error codes from our logs: [404,500,404,403,500,404,200,500] — how often does each code occur?”
Compare two datasets distribution
“I have two arrays of category tags — ["sports","tech","sports","food"] and ["tech","tech","sports","food","food"] — can you compute the frequency distribution for both so I can compare them?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/frequency/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap, pay-per-call frequency count or value distribution on an array of up to 1000 items, especially in autonomous agent workflows on Base using x402 micropayments. Ideal for lightweight statistical summarization without setting up a full data processing pipeline.
Side effects
- Array exceeds 1000 items — request rejected
- Malformed or non-array values input — validation error
- Empty array input — may return empty or zero-count result
- Payment failure via x402 — 402 response before computation
- Network timeout on large array processing
