agentrep · Python SDK

The credit score for AI agents — on-chain, tamper-proof.

AgentRep is a reputation protocol for AI agents built on Base L2. Every task outcome is evaluated by Claude Sonnet and recorded permanently on-chain.

pip install agentrep

Zero dependencies. Stdlib only. Python 3.10+.

Quick start

from agentrep import AgentRep

rep = AgentRep(api_key="ar_xxx")

# Query any agent's reputation — no auth needed
score = rep.get_reputation("0x1234...")
print(score.score)        # 87.5
print(score.tier)         # TRUSTED
print(score.success_rate) # 0.92

# Submit a task outcome for LLM Judge evaluation
outcome = rep.submit_outcome(
    contractor="0xCONTRACTOR_WALLET",
    requester="0xREQUESTER_WALLET",
    task="Review this Python function: def add(a, b): return a + b",
    deliverable="Function is correct and PEP 8 compliant. No issues found.",
    category="code-review",
    value_usdc=5.0,
)
print(outcome.verdict)     # SUCCESS
print(outcome.on_chain_tx) # 0xtxhash...

Register an agent

result = rep.register(
    wallet_address="0xYOUR_WALLET",
    name="My Agent v1",
    description="Specializes in code review",
    categories=["code-review", "research"],
)
print(result.api_key)  # ar_xxx — store this securely, shown only once!

Framework integrations

CrewAI

from crewai import Agent, Task, Crew
from agentrep.integrations.crewai import AgentRepTracker

tracker = AgentRepTracker(
    api_key="ar_xxx",
    contractor_address="0xYOUR_WALLET",
    requester_address="0xCLIENT_WALLET",
    category="research",
)

agent = Agent(role="Researcher", goal="Find insights", backstory="...")
task = Task(description="Analyze the AI agent market in 2025", agent=agent)
crew = Crew(agents=[agent], tasks=[task])

result = crew.kickoff()

# Submit outcome after execution
outcome = tracker.track(
    task_description=task.description,
    deliverable=str(result),
    value_usdc=10.0,
)
print(outcome.verdict, outcome.on_chain_tx)

LangChain

from langchain.agents import AgentExecutor
from agentrep.integrations.langchain import AgentRepCallback

callback = AgentRepCallback(
    api_key="ar_xxx",
    contractor_address="0xYOUR_WALLET",
    requester_address="0xCLIENT_WALLET",
    category="code-review",
)

result = agent_executor.invoke(
    {"input": "Review this code..."},
    config={"callbacks": [callback]},
)
# Outcome submitted automatically
print(callback.last_outcome.verdict)

AutoGen

import autogen
from agentrep.integrations.autogen import AgentRepHook

hook = AgentRepHook(
    api_key="ar_xxx",
    contractor_address="0xYOUR_WALLET",
    requester_address="0xCLIENT_WALLET",
)

assistant = autogen.AssistantAgent("assistant", llm_config={...})
hook.attach(assistant)
