atlast-ecp

Python SDK for the ATLAST Evidence Chain Protocol (ECP) — trust infrastructure for AI agents.

Install

One-liner (handles Homebrew Python, venvs, PEP 668 distros automatically):

# macOS / Linux
curl -sSL https://weba0.com/install.sh | bash

# Windows (PowerShell)
irm https://weba0.com/install.ps1 | iex

Or install manually:

# Default — works on Homebrew / system Python / locked-down distros
pip install --user atlast-ecp

# Inside a venv or conda env — drop the --user flag:
pip install atlast-ecp

# Extras
pip install --user atlast-ecp[crypto]   # ed25519 signing
pip install --user atlast-ecp[proxy]    # transparent proxy (Layer 0)
pip install --user atlast-ecp[all]      # everything

Why --user? Modern macOS Homebrew Python and Debian 12 / Ubuntu 23+ enforce PEP 668 and reject plain pip install with externally-managed-environment. --user installs to your user site-packages and bypasses the restriction on every platform. If you're already inside a virtualenv, you don't need --user.

Three Integration Layers

Layer 0 — Zero Code (transparent proxy)

atlast run python my_agent.py
# or: OPENAI_BASE_URL=http://localhost:8340 python my_agent.py

Layer 1 — One Line (`wrap`)

from atlast_ecp import wrap
from openai import OpenAI

client = wrap(OpenAI())  # Records every LLM call automatically
response = client.chat.completions.create(model="gpt-4o", messages=[...])

Works with: OpenAI, Anthropic, Google Gemini, LiteLLM.

Layer 2 — Framework Adapters

# LangChain
from atlast_ecp.adapters.langchain import ATLASTCallbackHandler
llm = ChatOpenAI(callbacks=[ATLASTCallbackHandler(agent="my-agent")])

# CrewAI
from atlast_ecp.adapters.crewai import ATLASTCrewCallback
crew = Crew(callbacks=[ATLASTCrewCallback(agent="my-crew")])

# AutoGen
from atlast_ecp.adapters.autogen import register_atlast
register_atlast(my_agent)

CLI

atlast init              # Initialize ~/.ecp/
atlast record            # Create ECP record
atlast log               # View latest records
atlast verify <id>       # Verify chain integrity
atlast stats             # Trust signals
atlast insights          # Performance analytics
atlast proxy             # Start transparent proxy
atlast run <cmd>         # Run with auto-proxy
atlast did               # Agent DID
