Entity-Graph Retrieval Improves AI Agent Memory
Norax AI published a technical blog post on 2026-06-27 describing an entity-graph retrieval method to improve memory retrieval for AI agents. The approach builds an entity graph from a memory store by extracting named entities, creating co-occurrence edges, weighting edges by co-occurrence counts, and grouping entities into communities using the Louvain algorithm. At query time the system extracts entities from the query, finds their communities, computes entity overlap between query and candidate memories (with direct matches scored higher and same-community matches given a smaller boost), and boosts memories that share entities or community membership. The author argues this method finds related memories that semantic/embedding search misses, requires no additional training or external API calls, and adds minimal latency.
x402 Reaches 119M Transactions; Accountability Layer Needed
The Base blockchain’s x402 payment flow has recorded over 119 million cumulative transactions with more than $35M total volume, and nominal gas costs (< $0.0001 per transaction). Cloudflare has integrated x402 into pay‑per‑crawl tooling and nous research uses it for per‑inference billing of the hermes 4 model, demonstrating production viability beyond developer experimentation. The author argues a missing accountability layer is required when autonomous agents act as financial principals spending on behalf of humans. MnemoPay positions itself as that accountability layer — offering an SDK that adds intent-linkage and signed receipts, an agent creditworthiness score (“Agent FICO”), and provenance for authorization — without changing the underlying payment rail. MnemoPay reports 672+ tests, v1.0.0-beta.1, and ~1.4K weekly npm downloads. The post frames this layer as essential as x402 usage moves toward consumer‑scale agent commerce.
