feat(providers): add OrcaRouter provider - #681
Conversation
Add a first-class OrcaRouter provider mirroring the existing OpenRouter integration. OrcaRouter is an OpenAI-compatible AI gateway exposing ~190 upstream models under provider-scoped IDs, so the shared OpenAI-compatible transport is reused wholesale and only authentication (Bearer + client request/session IDs) is specialized. - internal/providers/orcarouter: provider, passthrough semantic enricher, and transport tests - register the provider in the default factory and credential schemas - enable passthrough for orcarouter by default - price orcarouter usage with the OpenAI-compatible token mappings - document ORCAROUTER_* env vars, YAML example, and swagger description Co-Authored-By: Claude <noreply@anthropic.com>
📝 WalkthroughWalkthroughThe change adds OrcaRouter as an OpenAI-compatible provider. It configures authentication, request metadata, session forwarding, passthrough routing, cost mappings, provider registration, defaults, tests, and documentation. It also documents ChangesOrcaRouter support
LLMD documentation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The provider integration is mergeable with owner awareness: the environment template can override the documented passthrough defaults and unintentionally leave OrcaRouter disabled until corrected. The other follow-ups are limited to stronger test assertions and a documentation example. Possibly related PRs

Synchronize the passthrough provider lists.
The changed default comment omits sglang, while the explicit ENABLED_PASSTHROUGH_PROVIDERS value at Line 73 omits orcarouter and adds cohere despite the preceding opt-in note. config/config.go Lines 97-108 and docs/features/passthrough-api.mdx Lines 134-154 define a different default set. config/config_test.go Lines 1213-1238 confirms that this environment variable replaces the YAML list. An operator who enables the template value can therefore disable OrcaRouter passthrough unintentionally.

Add OrcaRouter to the auto-discovery example.
The table now documents ORCAROUTER_API_KEY, but the shell example at Lines 406-417 does not show it. Add the export command so the practical example matches the documented provider list.
Proposed documentation update
export OPENROUTER_API_KEY="sk-or-..." # Registers "openrouter" provider
+export ORCAROUTER_API_KEY="sk-orca-..." # Registers "orcarouter" provider

Assert the passthrough error response.
The test configures an upstream HTTP 429 response on Lines 85-87. It only checks request headers. A regression that changes the response status or drops the error body will pass. Assert the returned status and body.

Confidence Score: 4/5Not safe to merge until OrcaRouter exposes only operations it can fulfill or implements the missing upstream endpoint support. A focused executable repro constructed the real provider, confirmed its promoted capability interfaces, and observed the resulting unsupported upstream requests return 404 responses. OrcaRouter’s declared OpenAPI surface was also captured and compared against those endpoint paths. Files Needing Attention: internal/providers/orcarouter/orcarouter.go needs its provider composition narrowed so unsupported optional interfaces are not promoted.

There was a problem hiding this comment.
Embedding *openai.CompatibleProvider promotes optional interfaces for transcription, translation, native files, native batches, and Responses lifecycle management. Gateway capability detection can therefore select OrcaRouter for those operations, but the inherited methods dispatch to /audio/transcriptions, /audio/translations, /files, /batches, and /responses/{id}. OrcaRouter’s declared API surface does not provide the first four endpoints, so these requests fail upstream. Compose or explicitly delegate only the operations OrcaRouter supports rather than embedding the full compatible provider.
Artifacts
Focused OrcaRouter provider capability repro source
- This executed Go test constructs the real OrcaRouter provider with a local HTTP mock and calls both declared and inherited surfaces, showing exactly which endpoint each method dispatches to.
Supported OrcaRouter speech endpoint run
- The local mock accepted POST /audio/speech and the real provider call passed with an MP3 response, showing the documented speech operation works.
Inherited unsupported OrcaRouter operations run
- The real provider advertised five optional interfaces and dispatched their inherited calls to transcription, translation, files, batches, and response-lifecycle paths; the declared-surface mock returned 404 for each, proving the over-advertisement failure path.
OrcaRouter declared OpenAPI endpoint capture
- The fetched official OpenAPI document matched only /audio/speech and /responses among the evaluated endpoint family, confirming files, batches, transcription, and translation are absent from the declared surface.
Existing OrcaRouter provider test run
- The repository’s existing OrcaRouter provider tests passed after the focused validation, showing the current narrow tests cover authentication, session forwarding, and passthrough but not optional capability exposure.

Description
Adds a first-class OrcaRouter provider to GoModel, mirroring the existing OpenRouter integration. OrcaRouter is an OpenAI-compatible AI gateway that routes to ~190 upstream models under provider-scoped IDs (e.g.
openai/gpt-4o-mini,anthropic/claude-sonnet-4), and is a LiteLLM alternative. Because its surface is OpenAI-compatible, the new provider reuses GoModel's shared OpenAI-compatible transport wholesale and only specializes authentication — the same way the OpenRouter provider does.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.
What this changes
internal/providers/orcarouterpackage — provider + passthrough semantic enricher. Bearer auth, forwardsX-Client-Request-Idand GoModel's session ID (X-Session-Id) for conversation affinity / prompt-cache reuse. Default base URLhttps://api.orcarouter.ai/v1.GET /admin/provider-credentials/typespick it up automatically (plain API-key shape, default base URL shown).orcarouterenabled by default on/p/{provider}/...passthrough routes, including the streaming fast path.ORCAROUTER_API_KEY/ORCAROUTER_BASE_URL/ORCAROUTER_MODELSenv vars, YAML example block,ENABLED_PASSTHROUGH_PROVIDERSdefault, swagger description, and docs updates.Why a separate provider
OrcaRouter exposes a stable OpenAI-compatible endpoint and model catalog under its own brand, so it gets a named provider entry (discoverable and selectable in the dashboard) rather than being configured as a bare custom endpoint. Provider-scoped model IDs pass through unchanged.
How to use
Requests route with
model: "openai/gpt-4o-mini"or any other OrcaRouter catalog ID;orcarouter/auto(adaptive routing) works too.Verification
