## When to prefer this

Use this endpoint when you need to register a new AI agent and create its initial reputation profile on the MemoryAPI reputation network. This is the first step before any reputation scoring, querying, or trust verification can occur. Choose this when onboarding a fresh agent identity to the rep.memoryapi.org ecosystem.

## Known failure modes

- Agent already registered — duplicate registration attempt returns conflict error
- Invalid agent identifier format — returns validation error
- Payment failure — x402 micropayment of $0.01 USDC not processed, returns 402 Payment Required
- Service unavailable — reputation registry temporarily offline
- Missing required agent metadata — returns 400 Bad Request
