📦 Installation

pip install respan

Or with Poetry:

poetry add respan

🔑 Quick Start

1. Set up your API key

export RESPAN_API_KEY="your-api-key-here"

Or create a .env file:

RESPAN_API_KEY=your-api-key-here
RESPAN_BASE_URL=https://api.respan.ai  # optional

2. Basic Usage

from respan import DatasetAPI, ExperimentAPI, EvaluatorAPI

# Initialize clients
dataset_client = DatasetAPI(api_key="your-api-key")
experiment_client = ExperimentAPI(api_key="your-api-key")
evaluator_client = EvaluatorAPI(api_key="your-api-key")

# Create a dataset from logs
dataset = dataset_client.create({
    "name": "My Dataset",
    "description": "Dataset for evaluation",
    "type": "sampling",
    "sampling": 100
})

# List available evaluators
evaluators = evaluator_client.list()
print(f"Available evaluators: {len(evaluators.results)}")

# Run evaluation
evaluation = dataset_client.run_dataset_evaluation(
    dataset_id=dataset.id,
    evaluator_slugs=["accuracy-evaluator", "relevance-evaluator"]
)

🏗️ Core APIs

Dataset API

Manage datasets and run evaluations on your AI model outputs:

from respan import DatasetAPI, DatasetCreate

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

# Create dataset
dataset = client.create(DatasetCreate(
    name="Production Logs",
    type="sampling",
    sampling=1000
))

# Add logs to dataset
client.add_logs_to_dataset(
    dataset_id=dataset.id,
    start_time="2024-01-01T00:00:00Z",
    end_time="2024-01-02T00:00:00Z"
)

# Run evaluations
evaluation = client.run_dataset_evaluation(
    dataset_id=dataset.id,
    evaluator_slugs=["accuracy-evaluator"]
)

Experiment API

Run A/B tests with different model configurations:

from respan import ExperimentAPI, ExperimentCreate, ExperimentColumnType

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

# Create experiment
experiment = client.create(ExperimentCreate(
    name="Prompt A/B Test",
    description="Testing different system prompts",
    columns=[
        ExperimentColumnType(
            name="Version A",
            model="gpt-4",
            temperature=0.7,
            prompt_messages=[
                {"role": "system", "content": "You are a helpful assistant."},
                {"role": "user", "content": "{{user_input}}"}
            ]
        ),
        ExperimentColumnType(
            name="Version B", 
            model="gpt-4",
            temperature=0.3,
            prompt_messages=[
                {"role": "system", "content": "You are a concise assistant."},
                {"role": "user", "content": "{{user_input}}"}
            ]
        )
    ]
))

# Run experiment
results = client.run_experiment(experiment_id=experiment.id)

Evaluator API

Discover and use AI evaluators:

from respan import EvaluatorAPI

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

# List all evaluators
evaluators = client.list()

# Get specific evaluator details
evaluator = client.get("accuracy-evaluator")
print(f"Evaluator: {evaluator.name}")
print(f"Description: {evaluator.description}")

Prompt API

Manage prompts and their versions:

from respan import PromptAPI
from respan_sdk.respan_types.prompt_types import Prompt, PromptVersion

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

# Create a prompt
prompt = client.create()

# Create a version for the prompt
version = client.create_version(prompt.id, PromptVersion(
    prompt_version_id="v1",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Hello!"}
    ],
    model="gpt-4o-mini",
    temperature=0.7
))

# List all prompts
prompts = client.list()

# Get specific prompt with versions
prompt_details = client.get(prompt.id)

Log API

Create and manage AI application logs:

from respan import LogAPI, RespanLogParams

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

# Create log entry
log = client.create(RespanLogParams(
    model="gpt-4",
    input="What is machine learning?",
    output="Machine learning is a subset of AI...",
    status_code=200,
    prompt_tokens=10,
    completion_tokens=50
))

🔄 Async Support

All APIs support both synchronous and asynchronous operations:

import asyncio
from respan import DatasetAPI

async def main():
    client = DatasetAPI(api_key="your-api-key")
    
    # Use 'await' with 'a' prefixed methods for async
    datasets = await client.alist()
    dataset = await client.aget(dataset_id="123")
    
    print(f"Found {datasets.count} datasets")

asyncio.run(main())
