One endpoint, a token, and an engine that answers.
Post an expression, read the answer. The surface is one evaluate endpoint described in OpenAPI, with the same engine exposed as an MCP server for agents - and the whole journey from register to first computed answer is four HTTP requests.
It computes from your model, not from your files: Qurak solves what you write down, and does not read spreadsheets or datasets.
It is a computation service, not a runtime: expressions cannot touch files, the network or processes - refused by policy and enforced in a sandbox. What comes back is the mathematics.
Every example here was run by the engine that will run yours.
| You write | It answers |

| PowerMod[7, 128, 13] | 3 |
| FactorInteger[2^32 - 1] | {{3, 1}, {5, 1}, {17, 1}, {257, 1}, {65537, 1}} |
| Nest[#^2 + 1 &, 1, 4] | 677 |
Plot[Exp[-x/5] Sin[2 x], {x, 0, 10}] · Plots render as SVG, in the workbench and over the API.Qurak is an MCP server, so Claude, Cursor, VS Code and any other MCP client can hand it a calculation and get a real answer back instead of a plausible one. There is an HTTP API for everything else. Both are open on the free plan.
