+## Gemini's Response (April 13, 2026)
+
+**Summary:** Gemini can't run the API calls directly but provided exact copy-paste bash commands for NC1. Critical gotcha: the `$2a$10$` key MUST be wrapped in single quotes or Linux will expand `$2` and `$10` as script args, silently corrupting the key and causing 403s.
+
+**This explains every 403 we've seen all day when testing the key from the command line.**
+
+### The ID Lookup Commands (run on NC1)
+
+```bash
+# Step 1: Set key in single quotes (CRITICAL)
+export CF_API_KEY='$2a$10$OVK9ml7bEJdcfTJhBSuK1O5AFz2qq3mwpb35RTTwVfmdvzOFOA7M'
+
+# Step 2: Fetch version payload
+curl -s -X GET "https://api.curseforge.com/v1/games/432/versions" \
+  -H "Accept: application/json" \
+  -H "x-api-key: ${CF_API_KEY}" > cf_versions.json
+
+# Step 3: Extract Minecraft version IDs
+echo "Minecraft Version IDs:"
+jq -r '.data[] | select(.name=="1.21.1" or .name=="1.20.1" or .name=="1.16.5") | "\(.name): \(.id)"' cf_versions.json
+
+# Step 4: Extract mod loader IDs
+echo "Mod Loader IDs:"
+jq -r '.data[] | select(.name=="NeoForge" or .name=="Forge") | "\(.name): \(.id)"' cf_versions.json
+
+# Step 5: Clean up
+rm cf_versions.json
+```
+
+### Current Status
+
+Cannot run these today — rate limit from ModpackChecker calls is still active. Run tomorrow when quota resets.
+
+**Also to test tomorrow:** Whether the existing Core API key works for uploads, or if a separate Author Token is needed. Michael's approval email says "3rd Party CurseForge API" which may already cover uploads.
+
+---
+
+## Conclusion
+
+**Next steps (tomorrow, after rate limit resets):**
+1. Run the 5-step ID lookup on NC1 to get integer mappings
+2. Test upload endpoint with existing key — if 403, apply for Author Token
+3. Hardcode ID mappings into ffg-build.sh
+4. File Code bridge request for upload integration
