How this service works

Computational knowledge engine — math, science, geography, history, nutrition, finance, and more. Get answers as text, spoken audio, LLM-optimized data, or full structured results.

Output

Returns a JSON object containing a 'data' field with the spoken-form answer text optimized for voice or LLM consumption, along with payment settlement details (settled and authorized USDC amounts) and a unique request ID with a status URL for tracking.

Example use cases

Real-time nutrition fact lookup

“How many calories and grams of protein are in one cup of cooked quinoa? Give me the answer in metric units.”

Live math problem solving

“What is the spoken answer for the integral of x squared times e to the x, from 0 to 2?”

Geography and distance calculation

“What is the straight-line distance from London to Sydney in kilometers? Use metric units.”

When to prefer

Choose this endpoint when you need a concise, spoken-optimized answer to a factual or computational query — especially for voice assistants, audio pipelines, or LLM reasoning chains where a brief natural-language answer string is preferable over raw structured data. Prefer this over the full/structured Wolfram|Alpha endpoints when you only need the spoken answer text and want minimal payload size. Use the x402 micropayment model when you need pay-per-query billing without API key subscriptions.

Side effects

Query is ambiguous or unrecognized by Wolfram|Alpha — returns empty or no-result data
Timeout exceeded — if computation exceeds the specified timeout seconds, may return partial or no result
Payment failure — x402 micropayment not authorized, request rejected before processing
Invalid units value — only 'metric' or 'imperial' accepted; other strings may cause unexpected behavior
Network/service unavailability — upstream Wolfram|Alpha API unreachable
