Agent memory on a budget: stretch MemoClaw's free tier before you swipe

MemoClaw charges only for embedding or GPT-4o-mini operations, while most maintenance endpoints (list, export, stats, keyword search) are free. By batching stores, caching recalls, gating semantic search behind keyword lookups, and running audit crons on free endpoints, prototype OpenClaw agents can stay under the 100 paid-operation limit for weeks. Paying becomes worthwhile only when multi-agent teams need heavy concurrent recalls or team handoffs.
