How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing tier-4 statistical results for the provided array, which may include measures such as mean, median, variance, standard deviation, percentiles, min, max, and other descriptive statistics depending on the tier output.
Example use cases
Sales data distribution analysis
“I have a list of daily sales figures for last month — [1200, 980, 1450, 760, 1100, 1340, 890, 1500, 670, 1230] — can you compute the full stats breakdown for me, like mean, median, standard deviation, and any other descriptive stats?”
Sensor reading anomaly check
“Here are temperature readings from my IoT sensors over the past hour: [72.1, 71.8, 73.0, 98.4, 72.5, 71.9, 72.3]. Can you run statistical analysis on these values so I can see if that spike looks like a real outlier?”
Model output score evaluation
“I just got confidence scores back from my ML model for a batch of predictions: [0.91, 0.87, 0.54, 0.99, 0.73, 0.68, 0.95, 0.42]. Can you compute summary statistics on these so I can understand how consistent the model is performing?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v2/array-stats-pack/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, pay-per-call statistical computation on a numeric array without setting up your own math library or data pipeline. Ideal for autonomous agents that occasionally need descriptive statistics as part of a larger workflow and want to pay only per use at $0.0018 USDC. Best when already operating within an x402/Base payment ecosystem.
Side effects
- Empty or missing 'values' array returns an error or empty result
- Non-numeric values in the array may cause computation errors
- Payment failure via x402 protocol blocks the request
- Malformed JSON input returns a 400-level error
- Very large arrays may hit payload size limits on Cloudflare Workers
