Utility Tools

\n

Endpoint /tools adalah utilitas publik — tidak memerlukan autentikasi.\nBerguna untuk agen LLM yang membutuhkan waktu sisi server, matematika aman,\natau nilai acak.

\n

GET /tools/time

\n

Mengambil waktu server saat ini, zona waktu, dan offset UTC.

\n
curl https://synapse.schaefer.zone/tools/time

Respons:

\n
{\n  "time": "2026-06-27T14:30:00.000Z",\n  "timezone": "Europe/Berlin",\n  "offset": 120\n}

Kasus penggunaan: agen LLM yang perlu tahu "jam berapa sekarang" untuk\npenjadwalan, timestamp, atau perhitungan tanggal relatif.

\n

GET /tools/calc

\n

Kalkulator aman — hanya aritmetika, tanpa eval(). Mendukung +, -, *,\n/, %, (, ), dan angka.

\n
curl "https://synapse.schaefer.zone/tools/calc?expr=(10+5)*3"

Respons:

\n
{\n  "result": 45,\n  "expr": "(10+5)*3"\n}
Gunakan ini alih-alih mencoba melakukan matematika di kepala Anda atau melalui\nparsing string. Ini aman (tidak mungkin injeksi kode) dan akurat.

Operator yang didukung

\n\n

Contoh

\n
curl ".../tools/calc?expr=2+2"          # → 4\ncurl ".../tools/calc?expr=3.14*100"     # → 314\ncurl ".../tools/calc?expr=100%7"        # → 2\ncurl ".../tools/calc?expr=(2+3)*4-1"    # → 19

GET /tools/random

\n

Membuat nilai acak.

\n
# UUID v4\ncurl "https://synapse.schaefer.zone/tools/random?type=uuid"\n# → { "value": "a1b2c3d4-...", "type": "uuid" }\n\n# Integer (rentang default 0-100)\ncurl "https://synapse.schaefer.zone/tools/random?type=int&min=1&max=10"\n# → { "value": 7, "type": "int" }\n\n# Float\ncurl "https://synapse.schaefer.zone/tools/random?type=float&min=0&max=1"\n# → { "value": 0.7234, "type": "float" }\n\n# String hex\ncurl "https://synapse.schaefer.zone/tools/random?type=hex&min=8&max=16"\n# → { "value": "a3f7b2c1", "type": "hex" }\n\n# String alfabet\ncurl "https://synapse.schaefer.zone/tools/random?type=alpha&min=8&max=12"\n# → { "value": "kQmzPwXn", "type": "alpha" }

Kasus Penggunaan untuk Agen LLM

\n

Membuat ID unik

\n
ID=$(curl -s .../tools/random?type=uuid | jq -r .value)\ncurl -X POST .../memory -d "{\\"key\\": \\"task_$ID\\", ...}"

Menghitung persentase

\n
TOTAL=142\nDONE=87\nPERCENT=$(curl -s ".../tools/calc?expr=($DONE*100)/$TOTAL" | jq -r .result)\necho "Progress: $PERCENT%"

Mengambil timestamp saat ini

\n
NOW=$(curl -s .../tools/time | jq -r .time)\ncurl -X POST .../var -d "{\\"key\\": \\"last_run\\", \\"value\\": \\"$NOW\\"}"

Membuat data uji

\n
for i in {1..10}; do\n  NAME=$(curl -s ".../tools/random?type=alpha&min=5&max=10" | jq -r .value)\n  curl -X POST .../memory -d "{\\"key\\": \\"test_$i\\", \\"content\\": \\"$NAME\\"}"\ndone
