Python SDK

pip install atlast-ecp

wrap() — Zero-Code Integration

The simplest way to add evidence recording:

from openai import OpenAI
from atlast_ecp import wrap

client = wrap(OpenAI())
# Every call is now recorded — no other changes needed

Supports: OpenAI, Anthropic, Google Gemini, LiteLLM

from anthropic import Anthropic
from atlast_ecp import wrap

client = wrap(Anthropic())
response = client.messages.create(
    model="claude-3-sonnet-20240229",
    messages=[{"role": "user", "content": "Hello"}]
)
# Automatically recorded with latency, model, tokens, flags

Streaming

Streaming is fully supported. The SDK records after the stream completes:

stream = client.chat.completions.create(
    model="gpt-4",
    messages=[{"role": "user", "content": "Write a poem"}],
    stream=True
)
for chunk in stream:
    print(chunk.choices[0].delta.content, end="")
# Record created after stream ends

record() — Explicit Recording

For full control:

from atlast_ecp import record

record(
    in_content="Summarize this document: ...",
    out_content="The document discusses three key points...",
    model="gpt-4",
    latency_ms=1200,
    tokens_in=500,
    tokens_out=200,
    cost_usd=0.01,
    session_id="sess_abc",
)

record_minimal() — Lightweight

Minimum viable record (no signing, no chaining):

from atlast_ecp import record_minimal

record_minimal(
    in_content="input",
    out_content="output",
    model="gpt-4",
)

Framework Adapters

LangChain

from atlast_ecp.langchain import ATLASTCallbackHandler

handler = ATLASTCallbackHandler(session_id="my-session")
chain.invoke({"input": "..."}, config={"callbacks": [handler]})

CrewAI

from atlast_ecp.crewai import ATLASTCrewCallback

crew = Crew(
    agents=[...],
    tasks=[...],
    callbacks=[ATLASTCrewCallback(session_id="crew-run-1")],
)

AutoGen

from atlast_ecp.autogen import ecp_middleware

agent = ConversableAgent(
    "assistant",
    middleware=[ecp_middleware(session_id="autogen-1")],
)
