Works letter by letter in every script — accents, Cyrillic, Greek, Devanagari, Chinese and right-to-left Arabic — and adds an answer key with every word circled.\n\nMethodology:\n- Words are normalised (Unicode NFC, spaces and punctuation removed, optional capitals with the language’s rules, e.g. Turkish İ) and split into user-perceived characters (Unicode grapheme clusters, UAX #29): one character per cell.\n- Longest words are placed first at random allowed positions (right and down, optionally the two diagonals and all reversed directions); shared letters are preferred when allowed. With automatic size the grid grows from about √(letters × 2) until every word fits.\n- Empty cells get random letters taken from your words, so the filler matches the script. Any word that appears a second time by accident gets its filler letters redrawn, so each word can be found exactly once. Right-to-left word lists are mirrored so “forwards” reads right to left.\n\nChinese, Japanese and Korean grids print only characters in Printshop’s font subsets; missing characters are reported as a warning.", "tags": [ "apps" ], "x-mcp-tool": "printshop_word_search", "x-owner-app": "printshop", "requestBody": { "required": true, "content": { "application/json": { "schema": { "$ref": "#/components/schemas/PrintshopWordSearchInput" }, "examples": { "example1": { "summary": "Space words with diagonals", "value": { "seed": "space-1" } }, "example2": { "summary": "German animals, backwards too", "value": { "words": "Fuchs, Igel, Eichhörnchen, Dachs, Reh, Biber, Hase, Maus, Specht, Eule", "backwards": true, "lang": "de", "seed": "wald" } }, "example3": { "summary": "Arabic words (right to left)", "value": { "words": "شمس\nقمر\nنجمة\nسماء\nبحر\nجبل\nشجرة\nوردة", "lang": "ar", "diagonal": false, "seed": "ar-1" } } } } } }, "responses": { "200": { "description": "Calculation result envelope.", "content": { "application/json": { "schema": { "$ref": "#/components/schemas/PrintshopWordSearchResult" } } } }, "400": { "description": "Malformed JSON body.", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } }, "422": { "description": "Invalid input (see errors[]).", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } }, "429": { "description": "Rate limit exceeded (see Retry-After).", "content": { "application/problem+json": { "schema": { "$ref": "#/components/schemas/Problem" } } } } } } }, "/api/v1/tool": { "get": { "operationId": "getToolDefinition", "summary": "Inputs, output schema and examples for this tool", "responses": { "200": { "description": "Tool definition.", "content": { "application/json": { "schema": { "type": "object" } } } } } } } }, "components": { "schemas": { "Problem": { "type": "object", "description": "RFC 9457 problem details. 422 responses include per-field `errors`.", "required": [ "type", "title", "status", "detail" ], "properties": { "type": { "type": "string" }, "title": { "type": "string" }, "status": { "type": "integer" }, "detail": { "type": "string" }, "code": { "type": "string" }, "errors": { "type": "array", "items": { "type": "object", "required": [ "field", "message" ], "properties": { "field": { "type": "string" }, "message": { "type": "string" } } } } } }, "PrintshopWordSearchInput": { "type": "object", "additionalProperties": false, "properties": { "words": { "title": "Words", "description": "One word per line or separated by commas.
