Republic

Build LLM workflows like normal Python while keeping a full audit trail by default.

Visit https://getrepublic.org for concepts, guides, and API reference.

Republic is a tape-first LLM client: messages, tool calls, tool results, errors, and usage are all recorded as structured data. You can make the workflow explicit first, then decide where intelligence should be added.

Quick Start

pip install republic

from __future__ import annotations

import os

from republic import LLM

api_key = os.getenv("LLM_API_KEY")
if not api_key:
    raise RuntimeError("Set LLM_API_KEY before running this example.")

llm = LLM(model="openrouter:openrouter/free", api_key=api_key)
result = llm.chat("Describe Republic in one sentence.", max_tokens=48)

if result.error:
    print(result.error.kind, result.error.message)
else:
    print(result.value)

Why It Feels Natural

• Plain Python: The main flow is regular functions and branches, no extra DSL.
• Structured Result: Core interfaces return StructuredOutput, with stable ErrorKind values.
• Tools without magic: Supports both automatic and manual tool execution with clear debugging and auditing.
• Tape-first memory: Use anchor/handoff to bound context windows and replay full evidence.
• Event streaming: Subscribe to text deltas, tool calls, tool results, usage, and final state.
