ONE Engine Cumulative Sum (T2)
x402
ONE Engine Cumulative Sum (T2) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0007/call, status unknown (last checked 2026-10-02).
Computes the cumulative sum of an array of up to 1000 numbers, with optional scaling, offsetting, and output constraints.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the cumulative sum array derived from the input values, with optional constraints applied such as clamping to min/max bounds, scaling by a factor, adding an offset, rounding to a specified number of decimal digits, and resizing the output array length.
Example use cases
Running total of daily sales
“I have daily sales figures for the past week — [120, 340, 210, 450, 380, 290, 510] — can you compute the running total so I can see how revenue accumulated day by day?”
Cumulative frequency for histogram
“Here are my frequency counts per bucket: [5, 12, 23, 18, 9, 4, 1]. Can you compute the cumulative sums so I can plot a cumulative distribution chart?”
Progressive budget spend tracking
“Compute the cumulative sum of these monthly expenses — [800, 1250, 430, 970, 1100] — and cap each output value at a maximum of 5000 so I can track budget burn rate against my limit.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/cumulative-sum/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, fast, pay-per-call cumulative sum computation without spinning up local compute, especially in an agentic pipeline that uses x402 micropayments on Base. Ideal for autonomous agents that need on-demand numerical prefix-sum calculations with optional normalization (scaling, offsetting, clamping) as part of a larger workflow. Prefer over local computation when the agent lacks a math execution environment or when consistency and simplicity of a hosted API is preferred.
Side effects
- Input array exceeds 1000 elements — request rejected
- Non-finite values (NaN, Infinity) in input array — validation error
- Missing required 'values' field — 400 bad request
- Payment not provided or insufficient — 402 Payment Required
- Malformed JSON body — parsing error
