How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with tier field (value: 2) and a result field containing Tier 2 statistical outputs — likely including mean, median, mode, variance, standard deviation, min, max, range, and possibly skewness or other higher-order descriptive statistics computed over the input array.
Example use cases
Descriptive stats for survey responses
“I have a list of survey scores — [3, 5, 4, 2, 5, 4, 3, 5, 1, 4, 5, 2] — can you run the Tier 2 stats pack on them and give me the full summary?”
Analyze sales performance numbers
“Here are last quarter's weekly revenue figures: [8200, 9100, 7800, 10500, 11200, 9800, 8700, 10100]. Run the array stats pack at Tier 2 so I can see the distribution and key metrics.”
Quality control measurement analysis
“I've got a batch of 15 sensor readings from our production line: [99.1, 98.7, 100.2, 97.5, 99.8, 100.5, 98.3, 99.0, 101.1, 97.9, 100.0, 99.4, 98.6, 100.3, 99.7]. Can you compute the Tier 2 statistical breakdown for me?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v2/array-stats-pack/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a richer statistical summary than Tier 1 offers and your numeric dataset is already in array form. It is ideal for quick one-shot descriptive statistics on a batch of numbers without standing up your own compute. The per-call micropayment model makes it cost-effective for occasional or agent-driven use rather than high-frequency streaming analytics.
Side effects
- Empty or missing values array returns error or empty result
- Non-numeric values in the array may cause computation failure or be silently ignored
- Payment failure via x402 returns 402 status blocking access
- Malformed JSON body returns 400 bad request
- Very large arrays may time out on Cloudflare Workers edge
