With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability korea-company-intelligence-resolve-ef36ea9a ``` Example prompt: Can you resolve the Korean company with stock code 005930 and give me its stable companyId, DART corp code, and English name? ## When to prefer this Use this endpoint when you need to identify or canonicalize a South Korean company before performing downstream lookups (DART filings, KONEPS procurement records, financial data). It is the right choice when you have any one of: a KRX stock code, a DART corp code, a Korean business registration number, or a company name, and need to resolve it to a stable cross-registry identifier. Prefer this over general web search when you need a structured, machine-readable result with high confidence from authoritative Korean regulatory sources. ## Known failure modes - No company found for the given input — returns empty companies array with count 0 - Ambiguous name match — ambiguous flag set to true with multiple company candidates returned - Invalid business registration number format — 400 bad request - Invalid stock code format (not 6 alphanumeric chars) — 400 validation error - Company exists in KRX but not registered in DART — partial data returned - Payment not made or x402 auth failure — 402 Payment Required ## How this service works Use when an agent must identify a South Korean company before looking up its profile or public-procurement record. Input: one of business_number (10 digits), dart_corp_code, stock_code (KRX, e.g. 005930) or q (company name, exact match ignoring 주식회사/(주)/spacing); first wins. Output: JSON companies with stable companyId, Korean and English names, stock code, DART code, match type, ambiguous flag. Data: OpenDART, KONEPS. Example: ?stock_code=005930 ## Output A JSON object containing: the original query parameters echoed back, a count of matched companies, an ambiguous boolean flag, and an array of company records each with a stable companyId (e.g. kr-dart-00126380), Korean name, English name, KRX stock code, DART corp code, business registration number, match type (e.g. stock_code, name, business_number), and confidence score. Also includes data sources with retrieval timestamps and attribution strings from OpenDART. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [], "properties": { "q": { "type": "string", "examples": [ "삼성전자" ], "maxLength": 100, "description": "Company name (Korean or English), matched exactly after removing legal-form words" }, "stock_code": { "type": "string", "pattern": "^[0-9A-Za-z]{6}$", "examples": [ "005930" ], "description": "KRX stock code" }, "dart_corp_code": { "type": "string", "pattern": "^\\d{8}$", "examples": [ "00126380" ], "description": "OpenDART corp_code (8 digits)" }, "business_number": { "type": "string", "pattern": "^\\d{3}-?\\d{2}-?\\d{5}$", "examples": [ "1248100998" ], "maxLength": 12, "description": "Business registration number (사업자등록번호), 10 digits" } }, "additionalProperties": false } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "required": [ "query", "count", "ambiguous", "companies", "sources", "attribution", "note" ], "properties": { "note": { "type": "string" }, "count": { "type": "integer" }, "query": { "type": "object", "properties": { "q": { "type": [ "string", "null" ] }, "stockCode": { "type": [ "string", "null" ] }, "dartCorpCode": { "type": "null" }, "businessNumber": { "type": [ "string", "null" ] } } }, "sources": { "type": "array", "items": { "type": "object", "properties": { "provider": { "type": "string" }, "retrievedAt": { "ty … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "note": "companyId is stable: kr-dart- for DART-registered companies, kr-brn- otherwise.
