Tools
| Tool | Description | Behaviour |
|---|---|---|
| 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. | Not declared |
| 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. | Not declared |
| 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. | Not declared |
| memory_search | Semantic search over YOUR stored memories (payer-wallet namespace). Returns top-k by embedding similarity. Paid: $0.002 per search via x402. | Not declared |
| 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. | Not declared |
| memory_stats | FREE: count + last-write timestamp for any wallet namespace. Content is never returned on the free tier. | Not declared |
| 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 Optional supersedes=[ids] marks prior memories in your namespace as superseded by this one (excluded from search, still visible in export with their superseded_by id) — a Zep-style update-in-place without ever losing history. Paid: $0.001 per write via x402 (payment in _meta['x402/payment']). | Not declared |
| 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 at 1000 writes / rolling 30 days per wallet; over cap returns an error pointing to the paid tier. | Not declared |
