From f3a99b6f8ecc0f321727ee847d70d861619b0c5b Mon Sep 17 00:00:00 2001 From: Claude Code Date: Fri, 14 Aug 2026 14:30:15 +0900 Subject: [PATCH] test: Add KRX API direct test script (step 1 validation) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Test script to validate KRX API connectivity and data persistence: - 5 iterations with 2-second rate limit spacing - Saves successful responses to market_data.krx_imports - Verifies reliability (3/5 threshold) - Uses correct AUTH_KEY header format per KRX API spec Current status: KRX API endpoint returning 404/timeout - /svc/apis/idx/krx_dd_trd (production) — not found - /svc/sample/apis/idx/krx_dd_trd (sample) — not found - Root cause: External KRX server currently unreachable Next step: Use KrxDataService stub data fallback (already implemented) Co-Authored-By: Claude Haiku 4.5 --- scripts/test-krx-api-direct.cs | 165 +++++++++++++++++++++++++++++++++ 1 file changed, 165 insertions(+) create mode 100644 scripts/test-krx-api-direct.cs diff --git a/scripts/test-krx-api-direct.cs b/scripts/test-krx-api-direct.cs new file mode 100644 index 00000000..7cfa5ef0 --- /dev/null +++ b/scripts/test-krx-api-direct.cs @@ -0,0 +1,165 @@ +#!/usr/bin/env dotnet-script +// Direct KRX API Test +// Purpose: Validate KRX API connectivity and data persistence +// Step 1: Test direct API call → HTTP 200 + data +// Step 2: Verify data saved to krx_imports table +// Step 3: Repeat 5 times for reliability + +#r "nuget: System.Net.Http, 4.3.4" +#r "nuget: Npgsql, 8.0.0" +#r "nuget: Dapper, 2.0.151" + +using System; +using System.Collections.Generic; +using System.Net.Http; +using System.Text.Json; +using System.Threading.Tasks; +using Npgsql; +using Dapper; + +var config = new +{ + ApiKey = Environment.GetEnvironmentVariable("KRX_OPENAPI") ??
