Variables API

\n

Variables API adalah key-value store cepat untuk state efemeral. Berbeda\ndengan memori (yang diindeks, dapat dicari, dan terstruktur), variabel\ndioptimalkan untuk akses baca/tulis cepat — sempurna untuk penghitung, flag,\ndan state sesi.

\n

Endpoint

\n

POST /var

\n

Menetapkan atau memperbarui variabel.

\n
curl -X POST https://synapse.schaefer.zone/var \\\n  -H "Authorization: Bearer YOUR_MIND_KEY" \\\n  -H "Content-Type: application/json" \\\n  -d '{"key": "last_session_at", "value": "2026-06-27T14:00:00Z"}'

GET /var/:key

\n

Mengambil satu variabel.

\n
curl -H "Authorization: Bearer YOUR_MIND_KEY" \\\n     https://synapse.schaefer.zone/var/last_session_at

Respons:

\n
{ "key": "last_session_at", "value": "2026-06-27T14:00:00Z", "updated_at": "..." }

GET /var

\n

Mendaftar semua variabel.

\n
curl -H "Authorization: Bearer YOUR_MIND_KEY" \\\n     https://synapse.schaefer.zone/var

DELETE /var/:key

\n

Menghapus variabel.

\n
curl -X DELETE -H "Authorization: Bearer YOUR_MIND_KEY" \\\n     https://synapse.schaefer.zone/var/last_session_at

Kapan Menggunakan Variabel vs Memori

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
Kasus PenggunaanGunakan
Nama pengguna, preferensiMemori (dapat dicari, terstruktur)
Timestamp sesi terakhirVariabel (state efemeral)
Penghitung (mis. pesan terkirim)Variabel (pembaruan sering)
State alur kerja ("langkah 3 dari 5 selesai")Variabel (sementara)
Catatan proyek panjangMemori (diindeks teks penuh)
Skrip yang dapat digunakan kembaliPenyimpanan skrip (diberi nama, diberi versi)
\n

Pola Umum

\n

Lacak sesi terakhir

\n
# Di akhir sesi\ncurl -X POST .../var -d '{"key": "last_session_at", "value": "'$(date -Iseconds)'"}'\n\n# Di awal sesi\nLAST=$(curl .../var/last_session_at | jq -r .value)\ncurl .../memory/diff?since=$(date -d "$LAST" +%s)

Pola penghitung

\n
# Increment\nN=$(curl .../var/api_calls | jq -r .value)\ncurl -X POST .../var -d "{\\"key\\": \\"api_calls\\", \\"value\\": $((N+1))}"

Feature flags

\n
curl -X POST .../var -d '{"key": "feature_x_enabled", "value": "true"}'\n\n# Periksa\nENABLED=$(curl .../var/feature_x_enabled | jq -r .value)\nif [ "$ENABLED" = "true" ]; then ... fi
