model/provider: add orcarouter provider - #2558
zsanig22-dotcom wants to merge 1 commit into
Conversation
Add OrcaRouter as a first-class provider in the provider registry, mirroring the existing OpenAI-compatible providers. OrcaRouter is an OpenAI-compatible AI gateway that exposes a provider/model namespace across many models, with adaptive routing and failover behind the same endpoint. - Register the orcarouter provider in model/provider, backed by the OpenAI-compatible model path. - Add VariantOrcaRouter with the default base URL and ORCAROUTER_API_KEY env var, and infer it from api.orcarouter.ai base URLs. - Document orcarouter in the provider example flags.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This PR adds an opt-in OrcaRouter provider that sends prompts, files, responses, and credentials to an external gateway. Caller-supplied HTTP endpoints and unsafe redirects could expose the API key and model data, so the change is mergeable with explicit follow-up to require HTTPS and restrict redirects.

Protect OrcaRouter credentials and data in transit. Require HTTPS for OrcaRouter endpoint selection before attaching ORCAROUTER_API_KEY, and reject redirects to any host other than api.orcarouter.ai. Add regression tests covering matching HTTP endpoints and redirects that leave the approved HTTPS origin.

What changed
Adds OrcaRouter as a first-class provider in
model/provider, mirroring the existingopenai/anthropic/gemini/ollama/hunyuanentries:provider.Model("orcarouter", ...)now resolveshttps://api.orcarouter.ai/v1andORCAROUTER_API_KEYautomatically. OrcaRouter is an OpenAI-compatible AI gateway that, like OpenRouter, exposes a provider/model namespace across many models — while also combining adaptive routing, automatic failover, zero-markup inference, observability, guardrails, and agent-tool governance behind the same endpoint, plus gateway-level zero-trust security for AI agents (screening every prompt/response and governing every tool call on a default-deny basis, with no application code changes).Why
OpenRouter is already referenced in this repo's model metadata; registering OrcaRouter the same way beats forcing users through an anonymous custom base URL.
Testing
go build ./...,go vet,go test ./model/..., gofmt/goimports,golangci-lintall pass.provider.Model("orcarouter", ...)completion againstapi.orcarouter.aireturnedpong(HTTP 200).Notes for reviewers
The factory delegates to
openaiProviderwithVariantOrcaRouterpreset, inheriting all existing OpenAI-compatible behavior. Discord: discord.gg/YEubt8enRA · X: https://x.com/OrcaRouterI'm an engineer on the OrcaRouter team.
