沿用現有的 OpenAI、Anthropic、LangChain 或 Vercel AI SDK 程式碼，僅需修改 base URL。
自動故障回退、重試以及跨供應商、跨金鑰的負載平衡，讓單一供應商限流或故障時請求仍能完成。
每次呼叫都可追溯並留下日誌，搭配評測工具與 CLI 可在終端直接查詢日誌與軌跡。

Provision mailboxes on verified domains or a shared myagent.mx address, with clean JSON output that strips signatures and quotes.
Send over HTTP or SMTP using the same mailbox credential as a Bearer token and SMTP password, with Idempotency-Key retries and attachment support.
Bind keys to providers, delivery groups, weights, and quota windows so traffic stays inside the boundaries you set.
Signed webhooks for delivery and receipt events, an SSE stream for live mailbox clients, and typed change polling for resync.
