Sendmux is an email API built for AI agents. It gives each agent a real mailbox on a verified domain or a shared address, lets it send outbound mail through your own providers, and streams inbox events live so agents can react instead of polling.

OrcaRouter is an OpenAI-compatible AI gateway that grades every prompt and routes it to the best-value model, then layers on failover, guardrails, an agent firewall, and compliance tooling for production AI.
Each prompt is graded and routed to the model that clears your quality bar, with configurable fallback chains that retry before a response starts.
Pay provider prices with $0 per-token added on pay-as-you-go and subscriptions, or bring your own provider keys and credits.
PII shielding, jailbreak and injection blocking, and per-call approval for tool and MCP actions run before you are billed.
Request logs, per-prompt receipts, routing and spend dashboards, and copy-as-cURL make every call auditable and attributable.

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.

チームのための協調型受信トレイとメール管理

無料・オープンソース100以上のLLMをフェイルオーバー付きで統合するオープンソースのプロキシとSDKを提供するが、マネージドサービスではなくセルフホストが必要。

Routes requests across frontier models with automatic failover and analytics, serving as a straightforward alternative API proxy.
Gives developers a single OpenAI-compatible endpoint for multiple LLMs with failover, but offers fewer advanced routing rules.
