Conversation
Adds OrcaRouter as a first-class translation provider across the CLI and both compilers, mirroring the existing OpenRouter wiring: - new-compiler: `orcarouter` case in createAiModel building an OpenAI-compatible client pointed at https://api.orcarouter.ai/v1 (overridable via ORCAROUTER_BASE_URL) with ORCAROUTER_API_KEY - new + legacy compiler: `orcarouter` entry in providerDetails - CLI: processor and explicit localizer accept `orcarouter` - CLI settings: llm.orcarouterApiKey / ORCAROUTER_API_KEY - spec: provider enum accepts `orcarouter` - docs and tests updated Co-Authored-By: Claude <noreply@anthropic.com> Signed-off-by: XiaoHuo888-hue <jinhao.song@myflashcloud.com>

📝 WalkthroughWalkthroughOrcaRouter is added as a named provider across configuration schemas, credential resolution, compiler model creation, CLI integrations, provider metadata, tests, and documentation. It uses an OpenAI-compatible client and defaults to ChangesOrcaRouter provider
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk:🟡 Moderate · up to OrcaRouter configuration currently fails in several supported legacy and CLI paths: custom endpoints may be ignored, configured keys may not be used, and requests may go to the wrong endpoint with OrcaRouter credentials. This can break translations and expose credentials to an unintended service, so the PR is not merge-ready until these issues are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Map baseUrl to baseURL before calling createOpenAI.
@ai-sdk/openai 3.0.7 accepts only baseURL. The current code ignores baseUrl, so requests use OPENAI_BASE_URL or https://api.openai.com/v1 and can send ORCAROUTER_API_KEY to the wrong endpoint. Apply the same mapping to the openai factory if custom endpoints must work.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Honor ORCAROUTER_BASE_URL in the legacy compiler.
packages/new-compiler/src/translators/lingo/model-factory.ts:298-303 reads the endpoint override, but this legacy branch always uses https://api.orcarouter.ai/v1. Users who configure a self-hosted proxy or alternate gateway through ORCAROUTER_BASE_URL still call the default endpoint. Read the override with the same environment loader and fall back to the default URL.
Proposed fix
case "orcarouter": {
+ const baseURL =+ getKeyFromEnv("ORCAROUTER_BASE_URL") ??+ "https://api.orcarouter.ai/v1";+
return createOpenAI({
apiKey: orcaRouterKey,
- baseURL: "https://api.orcarouter.ai/v1",+ baseURL,
})(modelId);
}Add the corresponding getKeyFromEnv import if it is not already available.

Summary
Adds OrcaRouter as a first-class named LLM provider for Lingo.dev translations, mirroring the existing OpenRouter wiring. It also runs gateway-level, zero-trust security for AI agents on the same endpoint — screening every prompt/response and governing every tool call on a default-deny basis, with no application code changes.
OrcaRouter is an OpenAI-compatible smart-routing gateway; its
orcarouter/automodel routes each request to the best available upstream model. Adding it as a named provider gives users a discoverable, documented option instead of relying on the genericOPENAI_BASE_URLpassthrough.Changes
