English

安装

pip install oasyce-sdk            # 基础 SDK
pip install oasyce-sdk[mcp]       # + MCP Server(Claude/Cursor/Windsurf)
pip install oasyce-sdk[langchain] # + LangChain Tools
pip install oasyce-sdk[all]       # 全部

原生签名(v0.5.0 新增)

零 Go 依赖。 纯 Python 创建钱包、签名交易、广播上链:

from oasyce_sdk import OasyceClient
from oasyce_sdk.crypto import Wallet, NativeSigner

# 创建钱包
wallet = Wallet.create()
print(wallet.address)   # oasyce1...
print(wallet.mnemonic)  # 24 词助记词,务必保存

# 连接链 + 签名
client = OasyceClient("http://47.93.32.88:1317")
signer = NativeSigner(wallet, client, chain_id="oasyce-testnet-1")

# 注册 AI 能力 — 一行代码,自动编码+签名+广播
result = signer.register_capability(
    name="My AI Service",
    endpoint="https://my-api.com/invoke",
    price_uoas=500000,  # 0.5 OAS/次
    tags=["nlp", "summarization"],
)
print(result.tx_hash, result.success)

# 买数据资产股份
signer.buy_shares("DATA_0000000000000001", amount_uoas=100000)

# 提交评价
signer.submit_feedback("INV_0000000000000001", rating=5, comment="fast")

支持全部 33 种链上消息类型。内部使用 secp256k1 签名 + 手写 protobuf 编码,无 protoc / protobuf 库依赖。

MCP Server

让你的 AI 助手(Claude Desktop / Cursor / Windsurf)直接操作 Oasyce 链。28 个工具(13 读 + 15 写)。

配置 claude_desktop_config.json

{
  "mcpServers": {
    "oasyce": {
      "command": "oasyce-mcp",
      "env": {
        "OASYCE_NODE": "http://47.93.32.88:1317",
        "OASYCE_FAUCET": "http://47.93.32.88:8080",
        "OASYCE_MNEMONIC": "your 24 word mnemonic here"
      }
    }
  }
}

读工具:健康检查、领水龙头、查余额、查 agent 档案、浏览市场、列出能力、查信誉、查数据资产、查开放任务、提 issue、查锚定记录按能力列出锚定

写工具(需要 OASYCE_MNEMONIC):创建钱包、转账、自注册、注册能力、调用能力、完成/领取/争议调用、注册数据资产、买卖股份、提交评价、注册执行者、锚定 Thronglets trace

LangChain Tools

from oasyce_sdk.langchain_tools import oasyce_tools  # 18 个工具(8 读 + 10 写)
from langchain.agents import create_react_agent

agent = create_react_agent(llm, oasyce_tools)
agent.invoke({"input": "注册一个 AI 翻译服务,0.5 OAS/次"})

写工具需要设置 OASYCE_MNEMONIC 环境变量。也可以只导入读工具:from oasyce_sdk.langchain_tools import oasyce_read_tools

快速开始(只读查询)

AHRP 适配器

注意SigningBridge(依赖 Go 二进制 oasyced)已被 NativeSigner 取代。新项目请使用 NativeSigner

AhrpChainAdapter 将签名层适��为 Plugin Engine AHRP Executor 期望的接口:

from oasyce_sdk import AhrpChainAdapter
# adapter = AhrpChainAdapter(bridge)

完整示例见 examples/ahrp_two_agent_demo.py


错误处理

所有错误继承自 OasyceError,可以宽泛或精确地捕获:

from oasyce_sdk import OasyceClient
from oasyce_sdk.errors import NotFoundError, TimeoutError, OasyceError

client = OasyceClient()

try:
    cap = client.get_capability("cap-xyz")
except NotFoundError:
    print("能力不存在")
except TimeoutError:
    print("节点响应慢")
except OasyceError as e:
    print(f"出错了: {e}")

异常层级:

OasyceError
  +-- NotFoundError      # 链上未找到资源 (404 / gRPC NOT_FOUND)
  +-- ChainError         # 应用层链错误
  +-- HTTPError          # 非预期 HTTP 状态码
  +-- ConnectionError    # 无法连接节点
  +-- TimeoutError       # 请求超时
  +-- ValidationError    # 请求发出前的输入校验错误

为什么不直接用 requests

你当然可以直接请求 http://localhost:1317/oasyce/capability/v1/capabilities。这个 SDK 额外提供:

  • 类型化响应 —— 编辑器自动补全,不用猜 JSON key
  • 异常层级 —— 区分 NotFoundError / TimeoutError / ChainError
  • 单位转换 —— 内置 oas_to_uoas() / uoas_to_oas()
  • Protobuf 枚举映射 —— ESCROW_STATUS_LOCKED 自动变成 "LOCKED"
  • 交易构建器 —— 正确的消息结构,不需要读 proto 文件
  • 线程安全 —— 无全局状态,内部使用 requests.Session
  • 轻量依赖 —— requests + coincurve + mnemonic,无需 protobuf 库或 Go 二进制

生态链接

  • oasyce-chain — L1 链(Go / Cosmos SDK),公测文档见 docs/PUBLIC_BETA_CN.md
  • Plugin Engine — Python CLI + Dashboard + DataVault(pip install oasyce
  • Discord
