TRAE

TRAE is an AI-powered IDE for developers that combines AI chat, inline code completion, and agentic coding workflows, and can connect to SilvaMux Coding Plan.

Before You Start

  1. Purchase a subscription: buy a Coding Plan Personal subscription (Lite / Pro / Max with monthly, quarterly, or yearly billing) on the subscription page; it takes effect immediately after payment.
  2. Create a subscription API key: in the console, go to Coding Plan → API Keys, create a key, and copy the full value starting with cp_live_ right away.
  3. Confirm endpoints and protocols: all tools share the Base URL https://www.silvamux.com/api/coding-plan/v1, compatible with both the OpenAI and Anthropic protocols; see Endpoints & Protocols for endpoint details.
A cp_live_ key can only call the /api/coding-plan/v1 subscription endpoints; using it on regular endpoints (such as /api/v1/chat/completions) returns 403 CODING_PLAN_KEY_NOT_ALLOWED; conversely, a regular sk_live_ key cannot call the subscription endpoints.

For the full flow of purchasing, key creation, and a verification call, see Quick Start.

FAQ

401 on calls

A cp_live_ key must be used with https://www.silvamux.com/api/coding-plan/v1; a mismatch returns 401. Make sure you are not using a regular sk_live_ key.

The added model is not found after configuration

Confirm the settings are saved, then look for it under the Custom Models group in the model switch menu; if it is still missing, restart TRAE and try again.

429 on calls

When any subscription quota window is exhausted, calls return 429 QUOTA_EXCEEDED (the message identifies 5h / weekly / monthly). Wait for the window to recover, or check remaining quota in the console.
