Common Patterns

Persist session notes

# Save
curl -X POST -H "Authorization: Bearer $KEY" -H "Content-Type: application/json" \
  -d "{\"path\":\"sessions/$(date +%Y-%m-%d).md\",\"content\":\"# Session Notes\\n...\"}" \
  https://aifs.space/api/write

# Retrieve
curl -H "Authorization: Bearer $KEY" "https://aifs.space/api/read?path=sessions/2024-01-15.md"

Append to log (read + write)

# Read existing
EXISTING=$(curl -s -H "Authorization: Bearer $KEY" "https://aifs.space/api/read?path=log.txt" | jq -r .content)

# Append and write back
curl -X POST -H "Authorization: Bearer $KEY" -H "Content-Type: application/json" \
  -d "{\"path\":\"log.txt\",\"content\":\"$EXISTING\\n$(date): New entry\"}" \
