# Wolfram|Alpha Short Answer API

> Wolfram|Alpha Short Answer API is a paid API for AI agents from wolframalpha.x402.paysponge.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a single short plain-text answer to a factual, mathematical, or scientific query using Wolfram|Alpha's computational intelligence engine

## 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 wolfram-alpha-407df988
```

Example prompt: Ask Wolfram|Alpha to compute the integral of x^2 from 0 to 10 and give me the short answer.

## When to prefer this

Use this endpoint when you need a single short, definitive answer to a mathematical, scientific, unit conversion, or factual question and don't need rich structured data or step-by-step explanations. Prefer this over /v2/query when you only need the bottom-line answer in plain text and want the simplest, lowest-latency response. Ideal for quick lookups embedded in agent reasoning chains.

## Known failure modes

- Query not understood or too ambiguous — Wolfram|Alpha returns no result or empty response
- Payment not processed (x402 flow fails) — HTTP 402 returned before answer is delivered
- Rate limit or quota exceeded — HTTP 429 or service unavailable
- Invalid or missing 'input' query parameter — request schema validation error
- Query outside Wolfram|Alpha's knowledge domain — returns generic 'no result' response

## How this service works

GET /v1/result

## Output

A concise plain-text string containing the computed or looked-up answer to the query, such as a number, unit-converted value, date, or factual fact — no markup, just the direct result.
