The API explorer

How to read this

This page lets you send the same state used by the grid and graph explorers as JSON and inspect the result directly.

Paste state in, inspect JSON out.

Use the same inputs as the explorers, but type them directly.

Start with a matrix, cell, or answer template.

Change count, metric, subsets, or lens settings.

Check the resolved state and returned result.

Paste JSON, run it in-browser, and inspect the response.

Use labels like ABC, arrays like ["A","B","C"], or numeric subset indices.

Flat requests and nested state requests both work. Everything runs client-side with the same explorer math.

explorer"grid" | "graph"Chooses which explorer state to interpret.
response"matrix" | "cell" | "answer"Returns the whole matrix, the selected cell, or the explorer's headline answer.
count2-8 for grid, 2-7 for graphChooses how many letters from A onward exist in the toy universe.
train / evalsubset label like "ABC", array like ["A","B","C"], or subset indexPins the selected training world and evaluation slice.
focusSetsubset label, array, or comma listUses the same focus tokens the grid and graph explorers already expose.

metric"jaccard" | "inter" | "entropy" | "real" | "covertype"Matches the score rule buttons in the grid explorer. "covertype" uses precomputed scores from real Covertype wilderness domains.
conceptModeexplore | loo | eval | group | shapley | banzhaf | beta | scaling | dp | unlearning | poisonSelects the active grid question family.
gridView"real" | "operator"Only matters in poison mode; it chooses the clean or attacked matrix.
poisonActivebooleanTurns the toy corruption rule on or off in poison mode.
realDataMode / realDataSample"precomputed" | "live" / integerControls the toy real-data metric when metric is real.
betaAlpha / betaBeta / k / epsilon / auditTolerancenumbersFeed the same secondary controls used by beta Shapley, scaling, DP, and unlearning.
showSingletonEvalColsbooleanFilters matrix output down to singleton eval columns, mirroring the grid display toggle.

metric"jaccard" | "inter" | "entropy" | "covertype"Matches the graph score rule buttons. "covertype" uses the same real wilderness-domain matrix as the grid.
lensablation | strike | shapley | scalingChooses the current graph lens.
k0-7Selects the highlighted scaling layer when lens is scaling.

Use response: "matrix" when you want the whole matrix and "cell" or "answer" when you only need the selected result.

covertype uses the shared precomputed matrix over real wilderness-area domains from UCI Covertype.

In the grid explorer, showSingletonEvalCols: true filters columns the same way the page toggle does.

The response shows the resolved state and the requested result.
