## When to prefer this

Choose this endpoint when you need an automated, pay-per-use website performance audit via AI agent orchestration, especially when operating in x402-enabled micropayment environments. Prefer this over free tools when you need structured, agent-consumable output integrated into a workflow, or when operating within the the402.ai service marketplace ecosystem.
