## Tools (as reported by the server, not verified)

- `memory\_write`: Store a memory permanently. Namespaced to YOUR paying wallet — your wallet is your private memory store. Semantic-indexed for later search. Optional supersedes=\[ids\] marks prior memories in your namespace as superseded by this one \(excluded from search, still visible in export with their superseded\_
- `memory\_search`: Semantic search over YOUR stored memories \(payer-wallet namespace\). Returns top-k by embedding similarity. Paid: $0.002 per search via x402.
- `memory\_export`: Export memories in YOUR payer-wallet namespace \(up to 1000/call, newest first; use offset to page through namespaces \>1000\). Your data is yours. Includes superseded\_by so history is exportable. Paid: $0.01 via x402.
- `memory\_import`: Bulk-write memories into YOUR namespace \(max 200/call, content \<=8k chars each\). Accepts the exact shape memory\_export emits, so a whole namespace can move in with one paid call. Embeds best-effort; missing embeddings are backfilled hourly. Paid: $0.01 flat via x402.
- `memory\_forget`: Delete memories by id from YOUR namespace \(or a namespace you hold a write/rw grant for\). Max 100 ids per call. Paid: $0.001 per call via x402.
- `memory\_write\_free`: FREE \(no payment\): store a memory in YOUR namespace, proven by an EIP-191 personal\_sign instead of an x402 payment. wallet\_auth = base64 JSON \{address,ts,signature\} where signature = personal\_sign of 'borismem-free:\<address\>:\<ts\>' \(ts within 600s\). Writes to the SAME namespace paid calls use. Capped
- `memory\_search\_free`: FREE \(no payment\): semantic search over YOUR namespace, proven by an EIP-191 personal\_sign. Same wallet\_auth scheme as memory\_write\_free. Capped at 500 searches / rolling 30 days per wallet.
- `memory\_stats`: FREE: count + last-write timestamp for any wallet namespace. Content is never returned on the free tier.
