}'Why RelayX
Cost in every response
Read X-RelayX-Cost-Usd on every call; reconcile any window with GET /v1/usage.
OpenAI-compatible
Swap base_url and your existing SDKs keep working.
CN-friendly egress
Frontier models stay reachable from mainland China.
Outputs on our domain
Images, audio and video come back as URLs on our own R2 — your code never sees an upstream link.
