Quick Start

from sdkrouter import SDKRouter

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

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

Features

Chat Completions (OpenAI-Compatible)

# Non-streaming
response = client.chat.completions.create(
    model="anthropic/claude-sonnet-4",
    messages=[{"role": "user", "content": "Explain quantum computing"}],
    max_tokens=500,
)

# Streaming
for chunk in client.chat.completions.create(
    model="openai/gpt-4o",
    messages=[{"role": "user", "content": "Count to 5"}],
    stream=True,
):
    print(chunk.choices[0].delta.content or "", end="")

Structured Output (Pydantic)

Get type-safe responses with automatic JSON schema generation:

from pydantic import BaseModel, Field
from sdkrouter import SDKRouter

class Step(BaseModel):
    explanation: str = Field(description="Explanation of the step")
    result: str = Field(description="Result of this step")

class MathSolution(BaseModel):
    steps: list[Step] = Field(description="Solution steps")
    final_answer: float = Field(description="The final answer")

client = SDKRouter()
result = client.parse(
    model="openai/gpt-4o",
    messages=[
        {"role": "system", "content": "You are a math tutor. Show your work."},
        {"role": "user", "content": "Solve: 3x + 7 = 22"},
    ],
    response_format=MathSolution,
)

solution = result.choices[0].message.parsed
for i, step in enumerate(solution.steps, 1):
    print(f"{i}. {step.explanation} → {step.result}")
print(f"Answer: x = {solution.final_answer}")

Vision Analysis

result = client.vision.analyze(
    image_url="https://example.com/image.jpg",
    prompt="Describe this image",
)
print(result.description)
print(f"Cost: ${result.cost_usd:.6f}")

Quality Tiers

Tier	Model	Use Case
fast	gpt-4o-mini	Quick analysis, lower cost
balanced	gpt-4o	Default, good quality/cost ratio
best	claude-sonnet-4	Highest accuracy

result = client.vision.analyze(
    image_url="https://example.com/image.jpg",
    model_quality="best",  # fast | balanced | best
)

OCR (Text Extraction)

result = client.vision.ocr(
    image_url="https://example.com/document.jpg",
    language_hint="en",  # optional
)
print(result.text)

OCR Modes

Mode	Speed	Accuracy	Use Case
tiny	Fastest	Basic	Simple text, receipts
small	Fast	Good	Standard documents

maximum	Slow	Best	Complex layouts, handwriting

result = client.vision.ocr(
    image_url="https://example.com/document.jpg",
    mode="maximum",  # tiny | small | base | maximum
)

CDN File Storage

# Upload bytes
file = client.cdn.upload(
    b"file content",
    filename="document.txt",
    is_public=True,
)
print(file.url)
print(file.short_url)

# Upload from URL
file = client.cdn.upload(
    url="https://example.com/image.png",
    filename="image.png",
)

# List files
files = client.cdn.list(page=1, page_size=20)
for f in files.results:
    print(f"{f.filename}: {f.size_bytes} bytes")

# Get file details
file = client.cdn.get("file-uuid")

# Delete file
client.cdn.delete("file-uuid")

# Statistics
stats = client.cdn.stats()
print(f"Total files: {stats.total_files}")
print(f"Total size: {stats.total_size_bytes} bytes")

URL Shortener

# Create short link
link = client.shortlinks.create(
    target_url="https://example.com/very-long-url-here",
    custom_slug="my-link",  # optional
    max_hits=1000,  # optional limit

print(result.cleaned_html)
print(f"Original: {result.original_size} bytes")
print(f"Cleaned: {result.cleaned_size} bytes")
print(f"Compression: {result.compression_ratio:.1f}x")

Async Cleaning with Agent

For complex HTML or when you need extraction patterns:

# Submit and wait for results (recommended)
result = client.cleaner.clean_async(
    html_content,
    url="https://example.com/article",  # source URL for context
    task_prompt="Extract main article content, ignore navigation",
    output_format="markdown",
    wait=True,  # poll until complete
)
print(result.cleaned_html)

# Or submit without waiting (for manual polling)
job = client.cleaner.clean_async(
    html_content,
    task_prompt="Extract product details",
)
print(f"Job queued: {job.request_uuid}")

# Poll job status manually
status = client.cleaner.job_status(job.request_uuid)
print(f"Status: {status.status}")

# Get extraction patterns (reusable for similar pages)
patterns = client.cleaner.patterns(job.request_uuid)
for p in patterns.patterns:
    print(f"Selector: {p['selector']} ({p['type']})")

# Get full result
result = client.cleaner.get(job.request_uuid)
print(result.cleaned_html)

Web Search

Search the web using Anthropic's web_search tool:

from sdkrouter import SDKRouter, UserLocation

client = SDKRouter()

# Basic web search
result = client.search.query("latest AI developments 2026")
print(result.content)
print(f"Cost: ${result.cost_usd}")

# View citations
for citation in result.citations:
    print(f"- {citation.title}: {citation.url}")

# Search with domain filtering
result = client.search.query(
    "Python tutorials",
    allowed_domains=["python.org", "realpython.com"],
    blocked_domains=["spam-site.com"],
)

# Localized search
result = client.search.query(
    "weather forecast",
    user_location=UserLocation(country="US", city="San Francisco"),
)

# Fetch and analyze specific URL
result = client.search.fetch(
    "https://example.com/article",
    prompt="Extract the main points from this article",
)

Mode-Based Search

Use progressive search modes for different levels of analysis:

from sdkrouter import SDKRouter, SearchMode

client = SDKRouter()

# Research mode: LLM ranking + summary
results = client.search.query_async(
    "best Python web frameworks 2026",
    mode=SearchMode.RESEARCH,
    task_prompt="Rank by popularity and documentation quality",
    max_results=20,
    wait=True,
)
for item in results.ranked_results:
    print(f"- {item.title} (relevance: {item.relevance}, score: {item.relevance_score})")
print(f"Summary: {results.summary}")

# Get full results with metrics
result = client.search.results(str(results.uuid))
if result.agent_metrics:
    m = result.agent_metrics
    print(f"Duration: {m.total_duration_ms}ms")
    print(f"Cost: ${m.cost_usd}")

Analyze Mode: Entity Extraction

# Analyze mode adds entity extraction
results = client.search.query_async(
    "latest AI startup funding rounds 2026",
    mode=SearchMode.ANALYZE,
    task_prompt="Focus on funding news",
    wait=True,
)

# Get full results with entities
result = client.search.results(str(results.uuid))
if result.entities:
    for company in result.entities.companies or []:
        print(f"Company: {company.value} - {company.entity_context}")
    for amount in result.entities.amounts or []:
        print(f"Amount: {amount.value}")

Comprehensive Mode: Deep Analysis

# Comprehensive mode: fetches URL content for synthesis
results = client.search.query_async(
    "climate change policy updates 2026",
    mode=SearchMode.COMPREHENSIVE,
    task_prompt="Compare policy approaches across countries",
    wait=True,
    timeout=600.0,
)

result = client.search.results(str(results.uuid))
print(f"Synthesis: {result.synthesis}")
print(f"Detailed analysis: {len(result.detailed_analysis or [])} sources")

Search Modes

Mode	Capabilities	Use Case
search	Direct web search	Fast, simple queries
research	+ LLM ranking, summary	Ranked results with insights
analyze	+ Entity extraction	Extract companies, people, amounts
comprehensive	+ URL fetch, synthesis	Deep content analysis
investigate	+ Multi-query, cross-analysis	Complex investigations

Embeddings

Create text embeddings for semantic search and similarity:

# Single text embedding
result = client.embeddings.create("Hello, world!")
embedding = result.data[0].embedding
print(f"Dimensions: {len(embedding)}")

# Batch embeddings
texts = ["Python programming", "JavaScript coding", "Machine learning"]
result = client.embeddings.create(texts)
for i, item in enumerate(result.data):
    print(f"[{i}] {len(item.embedding)} dimensions")

# Custom model (larger dimensions)
result = client.embeddings.create(
    "Hello, world!",
    model="openai/text-embedding-3-large",  # 3072 dimensions
)

Available Models

Model	Dimensions	Use Case
openai/text-embedding-3-small	1536	Fast, cheap, default
openai/text-embedding-3-large	3072	Higher quality
openai/text-embedding-ada-002	1536	Legacy

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")
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",
    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
import asyncio

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

    # Async chat
    response = await client.chat.completions.create(
        model="openai/gpt-4o",
        messages=[{"role": "user", "content": "Hello!"}]
    )

    # Async structured output
    result = await client.parse(
        model="openai/gpt-4o",
        messages=[...],
        response_format=MyModel,
    )

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

asyncio.run(main())
