LimitGuard Reputation Score with Bayesian Trust Decay

Use this endpoint when you already have a baseline trust score and cluster assignment for an entity and want a time-decayed, Bayesian-updated reputation score with a confidence interval. Prefer this over the quick risk score endpoint when you have richer entity history (verification count, cluster, last verification timestamp) and need a statistically grounded output rather than a lightweight heuristic score.

• Missing required fields (entity_name, trust_score, cluster, last_verified_at) returns 400 validation error
• Invalid trust_score outside 0-100 integer range returns 422 unprocessable entity
• Stale last_verified_at timestamp may result in low confidence output rather than an error
• Payment failure via x402 returns 402 Payment Required before processing
• Unrecognized cluster string may reduce scoring accuracy without explicit error
