Store a piece of text for later similarity recall - a per-wallet semantic index an agent cannot host in-session. Returns an id. Prefer memory-write for structured state you will look up by exact key; this pair is for fuzzy, meaning-based retrieval. Pair with /api/memory/recall to retrieve by meaning, not exact key.
