sdkrouter 0.1.16

Unified SDK for AI services with OpenAI compatibility

SDKRouter

Unified Python SDK for AI services with OpenAI compatibility. Access 300+ LLM models through a single interface, plus vision analysis, image generation, audio (TTS/STT with real-time analysis), CDN, URL shortening, and HTML cleaning tools.

Installation

pip install sdkrouter

Quick Start

from sdkrouter import SDKRouter, Model

client = SDKRouter(api_key="your-api-key")

# OpenAI-compatible chat completions with Model builder
response = client.chat.completions.create(
    model=Model.cheap(),  # or "openai/gpt-4o-mini" for direct ID
    messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)

Features

Chat Completions (OpenAI-Compatible)

from sdkrouter import Model

# Non-streaming with smart model
response = client.chat.completions.create(
    model=Model.smart(),
    messages=[{"role": "user", "content": "Explain quantum computing"}],
    max_tokens=500,
)

# Streaming with fast model
for chunk in client.chat.completions.create(
    model=Model.fast(streaming=True),
    messages=[{"role": "user", "content": "Count to 5"}],
    stream=True,
):
    print(chunk.choices[0].delta.content or "", end="")

# Direct model ID still works
response = client.chat.completions.create(
    model="anthropic/claude-sonnet-4",
    messages=[{"role": "user", "content": "Hello!"}],
)

Intent-Based Model Routing

Use the Model builder for IDE autocomplete and validation, or raw alias strings:

from sdkrouter import Model

# Model builder (recommended) — IDE autocomplete on methods and kwargs
response = client.chat.completions.create(
    model=Model.cheap(),  # Cheapest available model
    messages=[{"role": "user", "content": "Hello!"}]
)

response = client.chat.completions.create(
    model=Model.smart(),  # Highest quality model
    messages=[{"role": "user", "content": "Write a poem"}]
)

response = client.chat.completions.create(
    model=Model.balanced(),  # Best value (quality/price ratio)
    messages=[{"role": "user", "content": "Summarize this article"}]
)

# Raw string syntax also works
response = client.chat.completions.create(
    model="@cheap",
    messages=[{"role": "user", "content": "Hello!"}]
)

LLM Models API

# List available models with pagination
models = client.llm_models.list(page=1, page_size=50)
for m in models.results:
    print(f"{m.model_id}: context={m.context_length}")

# Get model details
model = client.llm_models.get("openai/gpt-4o-mini")
print(f"Context: {model.context_length} tokens")
print(f"Vision: {model.supports_vision}")
print(f"Price: ${model.pricing.prompt}/M input")

# List providers
providers = client.llm_models.providers()
for p in providers.providers:
    print(f"{p.name}: {p.model_count} models")

# Calculate cost
cost = client.llm_models.calculate_cost(
    "openai/gpt-4o-mini",
    input_tokens=1000,
    output_tokens=500,
)
print(f"Input: ${cost.input_cost_usd:.6f}")
print(f"Output: ${cost.output_cost_usd:.6f}")
print(f"Total: ${cost.total_cost_usd:.6f}")

# Statistics
stats = client.llm_models.stats()
print(f"Total models: {stats.total_models}")
print(f"Vision models: {stats.vision_models}")

Token Utilities

from sdkrouter.utils import count_tokens, count_messages_tokens

# Count tokens in text
tokens = count_tokens("Hello, world!")
print(f"Tokens: {tokens}")

# Count tokens in messages
messages = [
    {"role": "system", "content": "You are helpful."},
    {"role": "user", "content": "Hello!"},
]
tokens = count_messages_tokens(messages)
print(f"Message tokens: {tokens}")

Logging

Built-in logging with Rich console output and file persistence:

from sdkrouter import get_logger

# Get a configured logger
log = get_logger(__name__)
log.info("Processing request")
log.debug("Debug details: %s", data)
log.error("Something failed", exc_info=True)

# With custom settings
log = get_logger(__name__, level="DEBUG", log_to_file=True)

Features

• Rich console output with colors and formatted tracebacks
• Automatic file logging with date-based rotation
• Auto-detection of project root for log directory
• Cross-platform log paths (macOS, Windows, Linux)
• Fallback to standard logging if Rich not installed

from sdkrouter import setup_logging, get_log_dir, find_project_root

# Configure logging globally
setup_logging(
    level="DEBUG",        # DEBUG | INFO | WARNING | ERROR | CRITICAL
    log_to_file=True,     # Write to file
    log_to_console=True,  # Output to console
    app_name="myapp",     # Log file prefix
    rich_tracebacks=True, # Rich exception formatting
)

# Get log directory path
log_dir = get_log_dir()  # e.g., /project/logs or ~/Library/Logs/sdkrouter

# Find project root
root = find_project_root()  # Searches for pyproject.toml, .git, etc.

Async Support

All features support async operations:

from sdkrouter import AsyncSDKRouter, Model
import asyncio

async def main():
    client = AsyncSDKRouter(api_key="your-api-key")

    # Async chat with Model builder
    response = await client.chat.completions.create(
        model=Model.cheap(),
        messages=[{"role": "user", "content": "Hello!"}]
    )

    # Async structured output
    result = await client.parse(
        model=Model.smart(json=True),
        messages=[...],
        response_format=MyModel,
    )

    # Async audio
    response = await client.audio.speech(input="Hello!", voice="nova")
    result = await client.audio.transcribe(file=audio_bytes)

    # Async streaming TTS
    async for item in client.audio.speech_stream(input="Stream me!", voice="nova"):
        ...

    # Parallel requests
    results = await asyncio.gather(
        client.vision.analyze(image_url="..."),
        client.cdn.list(),
        client.llm_models.stats(),
    )

asyncio.run(main())

Configuration

from sdkrouter import SDKRouter

# Environment variables (auto-loaded)
# SDKROUTER_API_KEY - API key
# SDKROUTER_BASE_URL - Custom base URL

# Direct configuration
client = SDKRouter(
    api_key="your-key",
    base_url="https://your-server.com",
    timeout=60.0,
    max_retries=3,
)

# Use OpenRouter directly
client = SDKRouter(
    openrouter_api_key="your-openrouter-key",
    use_self_hosted=False,
)

Type Safety

All responses are fully typed with Pydantic models:

from sdkrouter import Model
from sdkrouter.tools import (
    VisionAnalyzeResponse,
    OCRResponse,
    CDNFileDetail,
    ShortLinkDetail,
    CleanResponse,
    LLMModelDetail,
    ImageGenerateResponse,
    ImageGenerationDetail,
)

# IDE autocomplete works
result: VisionAnalyzeResponse = client.vision.analyze(...)
result.description  # str
result.cost_usd     # float
result.usage.total_tokens  # int

# Image generation types
gen: ImageGenerateResponse = client.image_gen.generate(...)
gen.image_cdn_url  # str
gen.cost_usd       # str (decimal)
gen.duration_ms    # int

Helpers

Re-exported parsing utilities from sdkrouter_cleaner:

from sdkrouter import json_to_toon, JsonCleaner, html_to_text, extract_links, extract_images

# Convert JSON/dict to TOON format
toon_str = json_to_toon({"name": "Product", "price": 29.99})

# Clean and normalize messy JSON strings
cleaner = JsonCleaner()
cleaned = cleaner.clean(messy_json_string)

# Extract plain text from HTML
text = html_to_text("<p>Hello <b>world</b></p>")
# "Hello world"

# Extract all links from HTML
links = extract_links("<a href='/page'>Link</a>", base_url="https://example.com")

# Extract all image URLs from HTML
images = extract_images("<img src='/img.png'>", base_url="https://example.com")
