| What makes it different | - Learns from outcomes and improves over time, unlike vector databases that only perform similarity search
- Works across every AI tool with a single API key, not locked to one platform
- Complementary to RAG: remembers outcomes and lessons, not just document similarity
- Free tier with full API access and MCP server, no credit card required
| - Human-approved mandates enforce intent, not just static limits or merchant category blocks
- Operates outside the agent in the issuer's authorization path, preventing agent bypass or override
- Creates tamper-evident audit trail linked to agent identity, run, and policy version
- Never holds funds or issues cards; integrates with existing issuer infrastructure
- Single mandate and policy core across multiple payment rails and issuers
