# Arithmetic Series Sum Calculator

> Arithmetic Series Sum Calculator is a paid API for AI agents from minia2a.uk, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes the sum of an arithmetic series given its parameters

## Facts

- Endpoint: GET https://minia2a.uk/x402/arithmeticSeriesSum?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability arithmetic-series-sum-calculator-8dad497a
```

Example prompt: Can you calculate the sum of an arithmetic series that starts at 3, has a common difference of 5, and runs for 20 terms?

## When to prefer this

Choose this endpoint when you need a quick, paid-per-call arithmetic series sum without standing up your own math logic, especially in agentic pipelines where you want a standardized computation API. Ideal for lightweight agents that need occasional arithmetic series results without bundling a math library.

## Known failure modes

- Missing or invalid query parameters result in an error response
- Non-numeric inputs for series parameters may cause a computation failure
- Large term counts could produce overflow depending on input bounds
- Payment not completed or x402 handshake failure returns 402 status

## How this service works

minia2a service: x402-arithmetic-series-sum

## Output

Returns the computed sum of the arithmetic series — a single numeric value representing the total of all terms in the sequence defined by the given parameters.
