Wolfram|Alpha Simple API — returns a full-page image answer to any natural-language query, paid per call via MPP/Tempo.
What it does
This endpoint wraps the Wolfram|Alpha Simple API through the Locus MPP (Micropayment Protocol) gateway. It accepts a natural-language query and returns a single image containing the complete Wolfram|Alpha result page — including all pods, graphs, and formatted data — rendered as a PNG. This is the visual-output variant of the Wolfram|Alpha API suite, useful when you need a screenshot-style answer rather than structured text or audio.
The endpoint is a POST at `/wolframalpha/simple` and requires a JSON body with at least the `i` field (the query string). Optional parameters let you control image width, font size, background/foreground colors, layout style (divider or labelbar), and unit system (metric or imperial). The response on successful payment is an image (HTTP 200).
Pricing is 55,000 base units of pathUSD (currency address `0x20c0…b9537d11c60e8b50`) per request, which equals $0.055 (5.5 cents) per call, settled on Tempo L2. The payment intent is "charge" (one-shot per request). Note: the probe returned 404 on HEAD/GET because this endpoint only accepts POST; the OpenAPI spec and the broader Locus gateway infrastructure confirm the endpoint is available. No response schema or example responses were provided in the source material.
Capabilities
Use cases
- —Generating a visual answer image for embedding in chat or reports
- —Answering math, science, or factual queries as a rendered image
- —Providing Wolfram|Alpha results in contexts where structured parsing isn't needed
- —Displaying rich graphical answers (plots, tables) without client-side rendering
Fit
Best for
- —Agents or apps that need a visual screenshot of Wolfram|Alpha results
- —Quick factual lookups rendered as shareable images
- —Scenarios where image output is preferred over text or structured data
Not for
- —Use cases requiring structured/parseable data (use the Full Results endpoint instead)
- —High-volume batch processing where image overhead is unnecessary
- —Applications needing spoken/audio answers (use the Spoken endpoint instead)
Quick start

}Endpoint
Quality
The OpenAPI spec provides a clear request schema, pricing, and endpoint metadata. However, the probe did not capture a live 402 challenge (POST was not attempted; HEAD/GET returned 404), no response schema or example response is available, and crawled pages all returned generic 404 JSON. Docs are thin — only the OpenAPI block and external references exist.
Warnings
- —Probe returned 404 on HEAD and GET; endpoint is POST-only so liveness via 402 challenge was not confirmed during probing.
- —No response schema provided — the image content type and format are inferred from the 'Simple (Image)' label but not documented in the spec.
- —Currency address 0x20c000000000000000000000b9537d11c60e8b50 is assumed to be pathUSD with 6 decimals; if decimals differ, the stated price of $0.055 would be incorrect.
- —All crawled documentation pages returned 'endpoint does not exist' errors; external docs at paywithlocus.com/skill.md were not fetched.
