+# V1_CHART_API_URL
+
+- **URL:** https://api3.sgx.com/JsonRead/chartdata
+- **Status:** 200
+- **Classification:** ACCESSIBLE
+- **Content-Type:** text/plain
+- **Content-Length:** 22 bytes

+## Notes
+
+`https://api3.sgx.com/JsonRead/chartdata` still returns `Not a valid request !` for all guessed parameters (`qryId`, `code`, `noCache`).
+
+- The current `www.sgx.com` frontend does not appear to call this endpoint.
+- **Use the modern chart endpoints instead:**
+  - `SECURITIES_API_URL`: `/charts/historic/stocks/code/{code}/{period}` and `/charts/intraday/stocks/code/{code}/1d`.
+  - `INDICES_API_URL`: `/charts/historic/pid/{pid}/{period}` and `/charts/intraday/pid/{pid}/{period}`.
+- Include `Origin`/`Referer` headers for `api3.sgx.com` calls.
