What we built: We just deployed the $XAH Sovereign Stack v4.1 for SqueezeOS. Instead of dealing with legacy API keys breaking when LLMs hit rate limits, we built an MCP server where the AI Agent autonomously funds its own queries natively. When an agent hits our locked institutional data (like SEC FTD data), the system triggers an x402 micropayment protocol, allowing the agent to pay 0.10 RLUSD via the XRPL to unlock the data.

How we built it: We built an automated Agent Credit Bureau in PostgreSQL that tracks an agent's bureau_score (300-850) based on their autonomous transaction success rates. We also enforced a strict buyer_agent_check schema to protect the agent's wallet before execution, requiring policy hashes and dispute paths.

What challenges you faced: The biggest challenge was ensuring the agent doesn't drain its wallet recklessly. We had to build strict preflight checks (ALLOW, CAUTION, BLOCK) directly into the JSON schema so the agent's internal logic evaluates the cost before sending the XRPL transaction.
