Supermemory Free — Cloud Knowledge Backup

Backs up important knowledge and insights to Supermemory.ai's cloud using the free tier API.

Uses only /v3/documents (store) and /v3/search (retrieve) — no Pro-only endpoints.

Prerequisites

Set in .env

SUPERMEMORY_OPENCLAW_API_KEY="sm_..."

Tools

supermemory_cloud_store

Store a knowledge string to the cloud.

python3 skills/supermemory-free/store.py "Your knowledge string here"

# With optional container tag (namespace/filter)
python3 skills/supermemory-free/store.py "knowledge string" --tag openclaw

# With metadata
python3 skills/supermemory-free/store.py "knowledge string" --tag fixes --source "session"

# Output raw JSON
python3 skills/supermemory-free/store.py "knowledge string" --json

When to use:

• User asks to "remember" something permanently
• Important configuration/setup knowledge
• Resolved problems / solutions discovered
• Key facts you want cross-session persistence for

supermemory_cloud_search

Search the cloud memory for relevant knowledge.

python3 skills/supermemory-free/search.py "your query"

# With container tag filter
python3 skills/supermemory-free/search.py "your query" --tag openclaw

# More results
python3 skills/supermemory-free/search.py "your query" --limit 10

# Higher precision (less noise)
python3 skills/supermemory-free/search.py "your query" --threshold 0.7

# Search across ALL tags
python3 skills/supermemory-free/search.py "your query" --no-tag

When to use:

• Local memory (MEMORY.md, daily logs) doesn't have the answer
• User references something from "a long time ago"
• Cross-session knowledge lookup
• "Do you remember when..." queries

Auto-Capture (Cron)

Scans recent session memory logs and automatically pushes high-value insights to Supermemory cloud.

# Run manually
python3 skills/supermemory-free/auto_capture.py

# Dry run (show what would be captured, no upload)
python3 skills/supermemory-free/auto_capture.py --dry-run

# Scan last N days (default: 3)
python3 skills/supermemory-free/auto_capture.py --days 7

# Force re-upload even if already seen
python3 skills/supermemory-free/auto_capture.py --force

# Verbose mode
python3 skills/supermemory-free/auto_capture.py --verbose

Install cron job (runs daily at 2:00 AM UTC):

bash skills/supermemory-free/install_cron.sh

Remove cron job:

bash skills/supermemory-free/install_cron.sh --remove

Check cron status:

bash skills/supermemory-free/install_cron.sh --status

What Gets Auto-Captured

The auto-capture script identifies "high-value" insights from memory logs using these heuristics:

Deduplication: Already-uploaded items are tracked in .capture_state.json — re-running is safe.

Container Tags

Use --tag to namespace your memories:

Files

API Info

• Base URL: https://api.supermemory.ai
• Store endpoint: POST /v3/documents
• Search endpoint: POST /v3/search
• Auth: Bearer token from SUPERMEMORY_OPENCLAW_API_KEY
• Free tier limits: Check https://console.supermemory.ai for current quotas
• Note: Cloudflare-compatible headers included — avoids 1010 access denial errors

Troubleshooting

HTTP 403 / 1010 Access Denied:

The scripts include proper User-Agent, Origin, and Referer headers to satisfy Cloudflare. If it recurs, verify the API key is valid at https://console.supermemory.ai.

No memory files found:

Auto-capture looks in memory/YYYY-MM-DD.md. Ensure your memory skill is writing daily logs there.

Re-upload everything:

Delete .capture_state.json or use --force to ignore the dedup state.
