Installation

go get github.com/WaveSpeedAI/wavespeed-go

API Client

Run WaveSpeed AI models with a simple API:

import "github.com/WaveSpeedAI/wavespeed-go"

output, err := wavespeed.Run(
    "wavespeed-ai/z-image/turbo",
    map[string]any{"prompt": "Cat"},
)
if err != nil {
    log.Fatal(err)
}

fmt.Println(output["outputs"].([]any)[0])  // Output URL

Authentication

Set your API key via environment variable (You can get your API key from https://wavespeed.ai/accesskey):

export WAVESPEED_API_KEY="your-api-key"

Or pass it directly:

import "github.com/WaveSpeedAI/wavespeed-go/api"

client := api.NewClient(api.WithAPIKey("your-api-key"))
output, err := client.Run(
    "wavespeed-ai/z-image/turbo",
    map[string]any{"prompt": "Cat"},
)

Options

All parameters are optional. Use option functions to customize behavior:

output, err := wavespeed.Run(
    "wavespeed-ai/z-image/turbo",
    map[string]any{"prompt": "Cat"},
    wavespeed.WithTimeout(60),           // Max wait time in seconds
    wavespeed.WithPollInterval(1.0),     // Status check interval
    wavespeed.WithSyncMode(true),        // Enable synchronous mode
    wavespeed.WithMaxRetries(3),         // Maximum task retries
)

Sync Mode

Use WithSyncMode(true) for a single request that waits for the result (no polling).

Note: Not all models support sync mode. Check the model documentation for availability.

output, err := wavespeed.Run(
    "wavespeed-ai/z-image/turbo",
    map[string]any{"prompt": "Cat"},
    wavespeed.WithSyncMode(true),
)

Retry Configuration

Configure retries at the client level:

import "github.com/WaveSpeedAI/wavespeed-go/api"

client := api.NewClient(
    api.WithAPIKey("your-api-key"),
    api.WithClientMaxRetries(0),       // Task-level retries (default: 0)
    api.WithMaxConnectionRetries(5),   // HTTP connection retries (default: 5)
    api.WithRetryInterval(1.0),        // Base delay between retries in seconds (default: 1.0)
)

Upload Files

Upload images, videos, or audio files:

import "github.com/WaveSpeedAI/wavespeed-go"

// Simple upload
url, err := wavespeed.Upload("/path/to/image.png")
if err != nil {
    log.Fatal(err)
}
fmt.Println(url)

// With timeout
url, err := wavespeed.Upload("/path/to/image.png", wavespeed.WithUploadTimeout(30))
