Quick Start

package main

import (
    "context"
    "fmt"
    "log"

    pluggedin "github.com/veriteknik/pluggedinkit-go"
)

func main() {
    // Initialize client
    client := pluggedin.NewClient("your-api-key")
    // For local development:
    // client := pluggedin.NewClientWithOptions("your-api-key", "http://localhost:12005", nil)

    ctx := context.Background()

    // List documents
    docs, err := client.Documents.List(ctx, &pluggedin.DocumentFilters{
        Source: pluggedin.SourceAll,
        Limit:  10,
    })
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("Found %d documents\n", docs.Total)

    // Search documents
    results, err := client.Documents.Search(ctx, "machine learning", nil, 10, 0)
    if err != nil {
        log.Fatal(err)
    }
    for _, result := range results.Results {
        fmt.Printf("%s - Relevance: %.2f\n", result.Title, result.RelevanceScore)
    }

    // Query RAG
    answer, err := client.RAG.AskQuestion(ctx, "What are the main features?")
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(answer)
}

Authentication

Get your API key from your Plugged.in Profile:

import (
    "os"
    pluggedin "github.com/veriteknik/pluggedinkit-go"
)

// Using environment variables (recommended)
client := pluggedin.NewClient(os.Getenv("PLUGGEDIN_API_KEY"))

// With custom configuration
import (
    "net/http"
    "time"
)

httpClient := &http.Client{
    Timeout: 120 * time.Second,
}

client := pluggedin.NewClientWithOptions(
    os.Getenv("PLUGGEDIN_API_KEY"),
    os.Getenv("PLUGGEDIN_BASE_URL"),
    httpClient,
)

// Update API key at runtime
client.SetAPIKey("new-api-key")

// Change base URL
client.SetBaseURL("http://localhost:12005")

Core Features

Document Management

List Documents

filters := &pluggedin.DocumentFilters{
    Source:        pluggedin.SourceAIGenerated,
    Tags:          []string{"report", "analysis"},
    Category:      pluggedin.CategoryDocumentation,
    Sort:          pluggedin.SortDateDesc,
    Limit:         20,
    Offset:        0,
    ModelProvider: "anthropic",
}

// Time filters
from := time.Date(2024, 1, 1, 0, 0, 0, 0, time.UTC)
to := time.Date(2024, 12, 31, 23, 59, 59, 0, time.UTC)
filters.DateFrom = &from
filters.DateTo = &to

response, err := client.Documents.List(ctx, filters)
if err != nil {
    log.Fatal(err)
}

for _, doc := range response.Documents {
    fmt.Printf("%s (%d bytes)\n", doc.Title, doc.FileSize)
    fmt.Printf("  Created: %s\n", doc.CreatedAt)
    fmt.Printf("  Tags: %v\n", doc.Tags)
}

Get Document

// Get document metadata only
doc, err := client.Documents.Get(ctx, "document-id", false, false)
if err != nil {
    log.Fatal(err)
}
fmt.Printf("Title: %s\n", doc.Title)
fmt.Printf("Version: %d\n", doc.Version)

// Get document with content and version history
docWithContent, err := client.Documents.Get(ctx, "document-id", true, true)
if err != nil {
    log.Fatal(err)
}
fmt.Println(docWithContent.Content)

// Check last access time
if docWithContent.LastAccessAt != nil {
    fmt.Printf("Last accessed: %s\n", *docWithContent.LastAccessAt)
}

Search Documents

filters := map[string]interface{}{
    "modelProvider": "anthropic",
    "dateFrom":      "2024-01-01T00:00:00Z",
    "tags":          "finance,q4",
}

results, err := client.Documents.Search(ctx, "quarterly report", filters, 10, 0)
if err != nil {
    log.Fatal(err)
}

fmt.Printf("Found %d results for query: %s\n", results.Total, results.Query)

for _, result := range results.Results {
    fmt.Printf("\n%s\n", result.Title)
    fmt.Printf("  Document ID: %s\n", result.DocumentID)
    fmt.Printf("  Relevance: %.2f\n", result.RelevanceScore)
    fmt.Printf("  Snippet: %s\n", result.Snippet)
    fmt.Printf("  Tags: %v\n", result.Tags)
}

Create AI-Generated Document

request := &pluggedin.CreateDocumentRequest{
    Title:   "API Integration Guide",
    Content: "# API Integration Guide\n\n## Introduction\n\n...",
    Metadata: map[string]interface{}{
        "format":   "md",
        "category": "documentation",
        "tags":     []string{"api", "guide"},
        "model": map[string]string{

            "provider": "anthropic",
            "version":  "20240229",
        },
        "prompt":     "Create an API integration guide",
        "visibility": "workspace",
    },
}

doc, err := client.Documents.Create(ctx, request)
if err != nil {
    log.Fatal(err)
}

fmt.Printf("Created document: %s\n", doc.ID)
fmt.Printf("Version: %d\n", doc.Version)

Update Document

request := &pluggedin.UpdateDocumentRequest{
    Operation: pluggedin.OpAppend,
    Content:   "\n\n## New Section\n\nAdditional content here.",
    Metadata: map[string]interface{}{
        "changeSummary": "Added implementation details section",
        "model": map[string]string{
            "name":     "gpt-4",
            "provider": "openai",
            "version":  "0613",
        },
    },
}

response, err := client.Documents.Update(ctx, "document-id", request)
if err != nil {
    log.Fatal(err)
}

fmt.Printf("Updated to version %d\n", response.Version)
fmt.Printf("Updated at: %s\n", response.UpdatedAt)

Delete Document

err := client.Documents.Delete(ctx, "document-id")
if err != nil {
    log.Fatal(err)
}
fmt.Println("Document deleted successfully")

RAG Operations

Simple Query

// Basic question answering
answer, err := client.RAG.AskQuestion(ctx, "What are the deployment procedures?")
if err != nil {
    log.Fatal(err)
}
fmt.Println("Answer:", answer)

// Check availability
status, err := client.RAG.CheckAvailability(ctx)
if err != nil {
    log.Fatal(err)
}
fmt.Printf("RAG Available: %v\n", status["available"])

// Get storage statistics
stats, err := client.RAG.GetStorageStats(ctx, "user-id-from-dashboard")
if err != nil {
    log.Fatal(err)
}
fmt.Printf("Documents: %d\n", stats.DocumentsCount)
fmt.Printf("Estimated storage: %.2f MB\n", stats.EstimatedStorageMB)

Query with Sources

result, err := client.RAG.QueryWithSources(
    ctx,
    "Explain the authentication flow",
    "",
)
if err != nil {
    log.Fatal(err)
}

fmt.Printf("Answer: %s\n", result.Answer)
fmt.Println("\nSources:")
for index, source := range result.Sources {
    var documentID string
    if index < len(result.DocumentIDs) {
        documentID = result.DocumentIDs[index]
    }
    fmt.Printf("- %s (%s)\n", source, documentID)
}

Find Relevant Documents

documents, err := client.RAG.FindRelevantDocuments(
    ctx,
    "user authentication",
    "",
    5, // Top 5 documents
)
if err != nil {
    log.Fatal(err)
}

for _, doc := range documents {
    fmt.Printf("- %s (%s)\n", doc.Source, doc.DocumentID)
}

File Uploads

Important: The Go SDK no longer exposes binary upload helpers. All previous upload functions now return descriptive errors so legacy code fails fast. Continue using DocumentsService.Create for AI-generated content and the Plugged.in web interface (or forthcoming ingestion tools) for binary files.

Error Handling

The SDK provides typed error structs for comprehensive error handling:

doc, err := client.Documents.Get(ctx, "invalid-id", false, false)
if err != nil {
    switch e := err.(type) {
    case *pluggedin.AuthenticationError:
        fmt.Println("Invalid API key - please check your credentials")
        // Refresh API key logic

    case *pluggedin.RateLimitError:
        fmt.Printf("Rate limited. Retry after %d seconds\n", e.RetryAfter)
        // Implement retry with backoff
        time.Sleep(time.Duration(e.RetryAfter) * time.Second)

    case *pluggedin.NotFoundError:
        fmt.Printf("Document not found: %s\n", e.ID)
        // Handle missing document

    case *pluggedin.ValidationError:
        fmt.Printf("Validation error on field '%s': %s\n", e.Field, e.Message)
        // Fix validation issues

    case *pluggedin.APIError:
        fmt.Printf("API error (%d): %s\n", e.StatusCode, e.Message)
        if e.Details != nil {
            fmt.Printf("Details: %v\n", e.Details)
        }

    default:
        fmt.Printf("Unexpected error: %v\n", err)
    }
}

Context and Cancellation

All SDK methods accept a context for cancellation and timeout control:

// With timeout
ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
defer cancel()

docs, err := client.Documents.List(ctx, nil)
if err != nil {
    if errors.Is(err, context.DeadlineExceeded) {
        fmt.Println("Request timed out")
    }
}

// With cancellation
ctx, cancel := context.WithCancel(context.Background())

// Cancel from another goroutine
go func() {
    time.Sleep(5 * time.Second)
    cancel()
}()

// This will be cancelled after 5 seconds
answer, err := client.RAG.AskQuestion(ctx, "Long running query")
if err != nil {
    if errors.Is(err, context.Canceled) {
        fmt.Println("Request was cancelled")
    }
}

Concurrent Operations

Leverage Go’s concurrency for parallel operations:

func fetchDocumentsConcurrently(client *pluggedin.Client) {
    ctx := context.Background()
    documentIDs := []string{"doc1", "doc2", "doc3", "doc4", "doc5"}

    type result struct {
        doc *pluggedin.Document
        err error
    }

    results := make(chan result, len(documentIDs))

    // Fetch documents concurrently
    for _, id := range documentIDs {
        go func(docID string) {
            doc, err := client.Documents.Get(ctx, docID, true, false)
            results <- result{doc, err}
        }(id)
    }

    // Collect results
    for i := 0; i < len(documentIDs); i++ {
        r := <-results
        if r.err != nil {
            fmt.Printf("Error fetching document: %v\n", r.err)
        } else {
            fmt.Printf("Fetched: %s\n", r.doc.Title)
        }
    }
}

Testing

Unit Testing with Interfaces

// Define interface for testing
type DocumentService interface {
    List(ctx context.Context, filters *DocumentFilters) (*ListDocumentsResponse, error)
    Get(ctx context.Context, id string, includeContent, includeVersions bool) (*Document, error)
}

// Test function
func TestDocumentList(t *testing.T) {
    // Mock implementation
    mockService := &MockDocumentService{
        ListFunc: func(ctx context.Context, filters *DocumentFilters) (*ListDocumentsResponse, error) {
            return &ListDocumentsResponse{
                Documents: []Document{{Title: "Test Doc"}},
                Total:     1,
            }, nil
        },
    }

    // Test
    response, err := mockService.List(context.Background(), nil)
    if err != nil {
        t.Fatalf("unexpected error: %v", err)
    }

    if response.Total != 1 {
        t.Errorf("expected 1 document, got %d", response.Total)
    }
}

Integration Testing

func TestDocumentLifecycle(t *testing.T) {
    if testing.Short() {
        t.Skip("skipping integration test")
    }

    client := pluggedin.NewClient(os.Getenv("PLUGGEDIN_API_KEY"))
    ctx := context.Background()

    // Create document
    doc, err := client.Documents.Create(ctx, &CreateDocumentRequest{
        Title:   "Test Document",
        Content: "Test content",
        Metadata: map[string]interface{}{
            "tags": []string{"test"},
        },
    })
    if err != nil {
        t.Fatalf("failed to create document: %v", err)
    }

    // Cleanup
    defer func() {
        _ = client.Documents.Delete(ctx, doc.ID)
    }()

    // Update document
    updateResp, err := client.Documents.Update(ctx, doc.ID, &UpdateDocumentRequest{
        Operation: OpAppend,
        Content:   "\nUpdated content",
    })
    if err != nil {
        t.Fatalf("failed to update document: %v", err)
    }

    if updateResp.Version <= doc.Version {
        t.Errorf("expected version to increase, got %d", updateResp.Version)
    }
}

Benchmarking

func BenchmarkDocumentSearch(b *testing.B) {
    client := pluggedin.NewClient(os.Getenv("PLUGGEDIN_API_KEY"))
    ctx := context.Background()

    b.ResetTimer()
    for i := 0; i < b.N; i++ {
        _, err := client.Documents.Search(ctx, "test query", nil, 10, 0)
        if err != nil {
            b.Fatalf("search failed: %v", err)
        }
    }
}

Advanced Configuration

Custom HTTP Transport

import (
    "net/http"
    "net/url"
    "time"
)

// Custom transport with proxy
proxyURL, _ := url.Parse("http://proxy.example.com:8080")
transport := &http.Transport{
    Proxy:           http.ProxyURL(proxyURL),
    MaxIdleConns:    100,
    IdleConnTimeout: 90 * time.Second,
}

httpClient := &http.Client{
    Transport: transport,
    Timeout:   2 * time.Minute,
}

client := pluggedin.NewClientWithOptions(
    "your-api-key",
    "https://plugged.in",
    httpClient,
)

Environment Variables

// Load from environment
type Config struct {
    APIKey  string
    BaseURL string
    Timeout time.Duration
}

func LoadConfig() *Config {
    timeout, _ := time.ParseDuration(os.Getenv("PLUGGEDIN_TIMEOUT"))
    if timeout == 0 {
        timeout = 60 * time.Second
    }

    return &Config{
        APIKey:  os.Getenv("PLUGGEDIN_API_KEY"),
        BaseURL: os.Getenv("PLUGGEDIN_BASE_URL"),
        Timeout: timeout,
    }
}

// Use configuration
config := LoadConfig()
httpClient := &http.Client{Timeout: config.Timeout}
client := pluggedin.NewClientWithOptions(config.APIKey, config.BaseURL, httpClient)

Rate Limiting

The SDK handles rate limiting automatically:

API Endpoints: 60 requests per minute
Document Search: 10 requests per hour for AI documents
RAG Queries: Subject to plan limits

// Implement retry with exponential backoff
func retryWithBackoff(ctx context.Context, fn func() error) error {
    maxRetries := 5
    baseDelay := 1 * time.Second

    for i := 0; i < maxRetries; i++ {
        err := fn()
        if err == nil {
            return nil
        }

        // Check if it's a rate limit error
        if rateLimitErr, ok := err.(*pluggedin.RateLimitError); ok {
            delay := time.Duration(rateLimitErr.RetryAfter) * time.Second
            fmt.Printf("Rate limited, waiting %v\n", delay)
            time.Sleep(delay)
            continue
        }

        // Exponential backoff for other errors
        delay := baseDelay * time.Duration(1<<i)
        fmt.Printf("Error: %v, retrying in %v\n", err, delay)
        time.Sleep(delay)
    }

    return fmt.Errorf("max retries exceeded")
}
