Provider Registration

Providers are registered via blank imports:

import (
    "github.com/plexusone/omniobserve/llmops"

    // Register one or more providers
    _ "github.com/agentplexus/go-opik/llmops"
    _ "github.com/plexusone/omniobserve/llmops/langfuse"
    _ "github.com/agentplexus/go-phoenix/llmops"
    _ "github.com/plexusone/omniobserve/llmops/slog"
)

// Open by name
provider, err := llmops.Open("opik", llmops.WithAPIKey("..."))

Direct SDK Access

For provider-specific features, use the underlying SDKs directly:

import "github.com/plexusone/omniobserve/sdk/langfuse"  // Langfuse SDK
import "github.com/agentplexus/go-opik"                   // Opik SDK
import "github.com/agentplexus/go-phoenix"                // Phoenix SDK
