The catalog
Base price 0.001 USDC per request via x402 on Base. Complex or guaranteed calls use the premium tier (0.005–0.01 USDC).
Context EngineLive
Session compaction: squeezes conversation history into a dense, reusable prefix so long sessions stay sharp. Up to −87% tokens.
$8 /mocompaction
Quality GatesLive
Five sequential checks before an answer deploys: completeness, memory-fact match, no hallucinations, style, safety.
0.001 USDC /req5 gates
Exact Hash SearchLive
Deterministic O(1) lookup by SHA-256 hash — ~1 µs, no embeddings, no collisions. Built for dedup and 'seen this before'.
0.001 USDC /req~1 µs
Truth GateSoon
Cross-check facts against known data before writing to memory. Blocks memory poisoning by false claims.

Semantic top-k over the whole memory by meaning, not exact match. Next-gen search on top of the exact hash index.
0.001 USDC /reqsemantic
Memory Write GuardSoon
Blocks prompt injection and 'ignore previous instructions' before they reach storage. Extends the truth gate.
0.001 USDC /reqinjection safe
Exact-Dedup & ConsolidationSoon
O(1) dedup by hash + 3-gram similarity threshold. Duplicates collapse, evidence merges into one node.
0.001 USDC /reqzero dupes
Cache-Stable Prompt LayoutSoon
Canonical prefix first, facts by tier, append-only tail — provider prompt-cache stays valid, up to ×10 fewer tokens.
0.001 USDC /req×10 tokens
Provenance GuardSoon
System prompts and role text never get stored as 'facts'. Every memory carries an auditable source.
0.001 USDC /reqauditable
Context Window GuardSoon
Pre-flight token estimate + auto compaction when the budget is exceeded. The biggest agent pain, handled.
0.001 USDC /reqno overflow
