What

Adds Eden AI as a provider.

Eden AI is an EU-based, OpenAI-compatible LLM gateway (one API key, one endpoint, many upstream vendors). Its /v3 API speaks the OpenAI Chat Completions protocol, so the provider reuses the existing OpenAI implementation with a different base URL, the same thin-wrapper approach MiniMax uses over the Anthropic provider (NewMiniMax returns *Anthropic; NewEdenAI returns *OpenAI).

Model ids are vendor-prefixed, e.g. edenai/openai/gpt-4o-mini, edenai/anthropic/claude-haiku-4-5, edenai/mistral/mistral-small-latest. parseModel splits on the first /, so edenai selects the provider and the remaining <vendor>/<model> is sent through to Eden AI unchanged.

Changes

  • internal/provider/edenai.go: NewEdenAI (thin wrapper over the OpenAI provider, base URL https://api.edenai.run/v3).
  • internal/provider/registry.go: edenai added to supportedProviders, the New dispatch, and the unsupported-provider error list.
  • internal/config/config.go: edenai -> EDENAI_API_KEY in knownAPIKeyEnvVars.
  • internal/provider/registry_test.go and internal/config/config_test.go: tests mirroring the MiniMax ones (constructor dispatch, base URL override, missing key, Supported, env var, ResolveAPIKey).
  • docs/src/providers.md: Eden AI row in the providers table.
  • CHANGELOG.md: Unreleased entry.

Testing

  • go build ./..., go vet ./..., gofmt and golangci-lint run (v2, the repo's linter) are all clean.
  • go test ./internal/provider/ ./internal/config/ passes (the new tests plus the existing suite, no regression).
  • Live: verified against the real Eden AI API with a real key, through provider.New("edenai", key, "") and Send. Three upstream vendors returned completions: openai/gpt-4o-mini, anthropic/claude-haiku-4-5, mistral/mistral-small-latest.

Summary

This update adds Eden AI support through the existing OpenAI-compatible provider. It registers the provider, resolves EDENAI_API_KEY, supports vendor-prefixed model IDs, documents the base URL override, and adds related tests and configuration documentation.

Changelog

Added

  • Eden AI provider support with https://api.edenai.run/v3 as the default base URL.
  • Support for edenai/<vendor>/<model> model identifiers.
  • EDENAI_API_KEY configuration and API key resolution.
  • AXE_EDENAI_BASE_URL support.
  • Eden AI constructor, registry, and configuration tests.

Use table-driven tests.

It looks like these new test functions are missing out on the table-driven fun! Both test files introduce new flat test functions instead of adopting the repository's standard table-driven test structure. As per coding guidelines, all test files must use table-driven tests with the []struct{name, input, want} pattern.

hey @MVS-source I pushed some changes. Can you rebase?

Eden AI is an EU-based, OpenAI-compatible LLM gateway. Its /v3 API speaks the
OpenAI Chat Completions protocol, so the provider wraps the OpenAI
implementation with a different base URL, mirroring the Atlas Cloud provider.
Model ids are vendor-prefixed (e.g. edenai/openai/gpt-4o-mini): the first path
segment selects the provider and the remainder is sent through as the model.

Wires edenai into the provider registry and the config env-var map, documents it
in README.md and docs/src/providers.md, and adds a CHANGELOG entry.

Thanks for the heads up, rebased onto master and force pushed.

The conflicts were all with the Atlas Cloud provider (#92), which landed in the same three places. That turned out to be useful: it is a cleaner template than what I had, so I aligned the Eden AI provider on it.

What changed since your last look:

  • EdenAI is now a struct embedding *OpenAI and delegating to NewOpenAI(apiKey, WithOpenAIBaseURL(baseURL)), instead of returning a bare *OpenAI and building the HTTP client by hand. Same shape as AtlasCloud.
  • Missing key now returns a ProviderError with ErrCategoryAuth and names the env var, instead of a generic fmt.Errorf. This was CodeRabbit's second point, and Atlas Cloud does the same.
  • Tests moved to the table-driven style, which was CodeRabbit's first point. TestNew_EdenAI and TestResolveAPIKey_EdenAI are tables now, Eden AI joined the existing TestAPIKeyEnvVar_KnownProvider table rather than getting its own function, and there is a new edenai_test.go mirroring atlascloud_test.go.
  • Docs I had missed: the README provider row, the [providers.edenai] block in the config.toml example, and a usage note for the vendor-prefixed model ids.

Verification on the rebased tree:

  • go build ./..., go vet ./... and gofmt are clean
  • go test ./... passes, full suite
  • golangci-lint run reports 0 issues
  • Live against the real API: edenai/openai/gpt-4o-mini, edenai/anthropic/claude-haiku-4-5 and edenai/mistral/mistral-small-latest all return completions. Streaming works through the embedded provider. An invalid key surfaces as auth: Unauthorized. AXE_EDENAI_BASE_URL pointed at the EU host also works, which is why it is mentioned in the docs.

Happy to adjust anything if you would rather I kept the original constructor signature.

Security Misconfiguration

Reachability: Internal
Exploitability: Difficult
CWE: CWE-319 — Cleartext Transmission of Sensitive Information

Require an explicit policy for custom Eden AI URLs. NewEdenAI accepts any configured base URL, and both OpenAI request paths send Authorization: Bearer ... to that URL. A configured http:// endpoint can therefore transmit the key in cleartext.

Do not reject every HTTP URL. The repository intentionally supports HTTP for local or private OpenAI-compatible endpoints, including Ollama and the existing Eden AI test. Require absolute URLs with an input-category ProviderError, and make plain HTTP an explicit opt-in or trusted-endpoint exception. Update tests for HTTPS, relative URLs, and the permitted HTTP exception.
