How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing tier-1 statistical output for the input array, including computed metrics such as mean, median, min, max, standard deviation, and/or variance depending on the tier level.
Example use cases
Sensor data statistical summary
“I have a batch of temperature readings from my IoT sensors: [22.1, 23.5, 21.8, 24.0, 22.7, 23.1]. Can you compute the full statistical summary — mean, median, min, max, and standard deviation?”
Financial returns distribution analysis
“Here are my monthly portfolio returns for the year: [0.03, -0.01, 0.05, 0.02, -0.02, 0.04, 0.01, 0.06, -0.03, 0.02, 0.05, 0.03]. What are the key stats — average return, variance, min and max?”
Survey response score aggregation
“I collected these satisfaction scores from a user survey: [7, 8, 6, 9, 10, 5, 8, 7, 9, 6, 8]. Can you give me a statistical breakdown — average score, spread, and any other summary stats?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v2/array-stats-pack/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost, fast, pay-per-call statistical summary of a numeric array and are already using the x402 micropayment protocol on Base. It is ideal for autonomous agents that need on-demand descriptive statistics without hosting their own compute, and when cost per call must remain minimal (sub-cent range).
Side effects
- Empty or missing 'values' array returns an error or empty result
- Non-numeric values in the array may cause computation errors or be ignored
- Payment failure via x402 returns a 402 Payment Required response before processing
- Malformed JSON body results in a 400 Bad Request
- Very large arrays may hit Cloudflare Worker size or timeout limits
