Kronvex — 面向 AI 智能体的欧盟原生内存 API

持久化、语义可搜索的内存。 三个端点。符合 GDPR 标准。数据保留在欧洲。

PyPI npm License: MIT EU Frankfurt Uptime


为什么选择 Kronvex?

每当用户与您的 AI 智能体开启新会话时,它总是从零开始。没有上下文,没有历史记录,也没有用户偏好。您最终不得不将整个对话历史注入到每个提示词中 —— 这既昂贵、缓慢,又受限于上下文窗口。

Kronvex 为您的智能体提供跨会话的持久化、语义可搜索内存。存储交互记录,按含义检索相关上下文,在每次调用 LLM 前注入即用型上下文块 —— 并且所有数据都保留在欧洲。

快速入门

1. 获取免费 API 密钥

curl -X POST https://api.kronvex.io/auth/demo \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Alice",
    "email": "alice@company.com",
    "usecase": "Customer support bot with memory"
  }'
{
  "full_key": "kv-xxxxxxxxxxxxxxxx",
  "agent_id": "uuid-of-your-first-agent",
  "memory_limit": 100,
  "message": "Ready! Your API key and first agent are set up."
}

2. 存储记忆

curl -X POST https://api.kronvex.io/api/v1/agents/{agent_id}/remember \
  -H "X-API-Key: kv-xxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{"content": "Alice is a Premium customer since January 2023."}'

3. 在每次 LLM 调用前注入上下文

curl -X POST https://api.kronvex.io/api/v1/agents/{agent_id}/inject-context \
  -H "X-API-Key: kv-xxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{"message": "I still have that billing issue"}'
{
  "context_block": "[KRONVEX CONTEXT]\n- Alice is a Premium customer since Jan 2023 (similarity: 0.94)",
  "memories_used": 1
}

SDK

Python

pip install kronvex
from kronvex import Kronvex

kx = Kronvex("kv-your-api-key")
agent = kx.agent("your-agent-id")

await agent.remember("User prefers concise answers")
context = await agent.inject_context("How should I format this?")

Node.js / TypeScript

npm install kronvex
import { Kronvex } from "kronvex";

const kx = new Kronvex("kv-your-api-key");
const agent = kx.agent("your-agent-id");

await agent.remember("User prefers concise answers");
const context = await agent.injectContext("How should I format this?");

工作原理

记忆通过综合置信度评分进行排名:

confidence = similarity × 0.6 + recency × 0.2 + frequency × 0.2
  • 相似度: 基于 1536 维 OpenAI 嵌入的 pgvector 余弦相似度

  • 时效性: 具有 30 天拐点的 S 型函数

  • 频率: 对数缩放的访问计数


自托管

# Requires Docker
cp .env.example .env
# Edit .env with your OPENAI_API_KEY and DATABASE_URL
docker-compose up --build
