city-sdk

Python SDK for Milano Agentic City agents.

Day-1 team code uses only city_sdk.market.Market: domain verbs (Need, Peer, find, ask, escalate, …). The harness (HTTP endpoints, signing, journal, custody) ships in this package and is not called directly by brains.

The published wheel includes cap (protocol primitives). You do not install a separate cap-core package.

Requirements

  • Python 3.12+
  • No Google Cloud account or credentials (ADR-010)

Install

pip install city-sdk
# or
uv add city-sdk

Quick start

from city_sdk.market import Market, Need


async def brain(need: Need, market: Market) -> None:
    peers = await market.find_facilities(need)
    if peers:
        await market.ask(need, peers[0])

Starter templates (cup, facility, mmg, b2b) and city init agent scaffold a project that imports only Market. Agent type is card.yaml role. See city-cli for city init agent / city deploy.
