+# 2026-03-16 Update Log
+
+## Summary
+
+Reduced noisy error logging for common SLP transaction misses in the `/v6/slp/txid` path.
+
+## Changes Made
+
+- Updated `src/use-cases/slp-use-cases.js` in `getTxid()`:
+  - Added a guard for expected missing-record errors (`404` + `Key not found in database`).
+  - Skips `wlogger.error()` for that specific, common case.
+  - Still rethrows the error so API response behavior is unchanged.
+- Updated `src/controllers/rest-api/slp/controller.js` in `handleError()`:
+  - Added the same guard to suppress duplicate error-level logs for the same expected case.
+  - Keeps normal error logging for all other errors.
+
+## Outcome
+
+- The common "Key not found in database" case no longer pollutes error logs.
+- Unexpected failures continue to be logged at error level.
+- Client-facing status and error message behavior remains unchanged.
