Built for Every Workflow为各种工作流而构建

Developer Daily Workflow开发者日常工作流

Verify API responses without leaving the terminal. Run codegen to paste production-ready code directly into your project.无需离开终端即可验证 API 响应，并通过 codegen 将生产可用代码直接放入项目。

developer
$ qveris discover "geocoding API"
$ qveris call 1 --params '{"address":"SF"}'
$ qveris codegen python

Agent Automation PipelinesAgent 自动化管道

Let your AI agent discover and call APIs through shell pipes — zero schema injection overhead.让 AI Agent 通过 Shell 管道发现并调用 API，不产生 Schema 注入开销。

agent
$ qveris discover "weather forecast" --json --limit 1 |
  jq -r ".results[0].tool_id" |
  xargs -I {} qveris call {} --json

Batch Data Collection批量数据采集

Combine with shell pipes for batch operations across multiple inputs — one loop, unlimited symbols.结合 Shell 管道对多个输入执行批量操作，一个循环即可处理任意数量的股票代码。

batch
$ for symbol in AAPL GOOGL MSFT; do
    qveris call finance.stock_quote \
      --params "{\"symbol\":\"$symbol\"}" --json
  done | jq -s "."

Frequently Asked Questions常见问题

What is QVeris CLI?什么是 QVeris CLI？
QVeris CLI is a command-line tool that lets developers and AI agents discover, inspect, and execute 10,000+ API capabilities using natural language — from any terminal, without documentation hunting or boilerplate code. It runs as a subprocess, which means zero tool schema injection into LLM context windows.QVeris CLI 是命令行工具，让开发者和 AI Agent 能够从任意终端用自然语言发现、检查和执行 10,000+ 项 API 能力，无需翻阅文档或编写样板代码。它作为子进程运行，因此不会把 Tool Schema 注入 LLM 上下文窗口。
How does QVeris CLI reduce LLM prompt tokens?QVeris CLI 如何减少 LLM Prompt Tokens？
Unlike MCP Server which injects full tool schemas into LLM context (often thousands of tokens for 50+ tools), CLI runs as a subprocess — one shell command in, JSON result out. This cuts prompt token overhead by up to 80% compared to MCP at scale, because tool schemas never enter the LLM context window. The agent only sees the structured JSON result, not the tool definition.MCP Server 会把完整 Tool Schema 注入 LLM 上下文，50+ 个 Tool 往往需要数千 Tokens；CLI 则以子进程运行，输入一条 Shell 命令，输出 JSON 结果。由于 Tool Schema 不进入上下文窗口，大规模使用时可将 Prompt Token 开销降低最多 80%。Agent 只会看到结构化 JSON 结果，而不是 Tool 定义。
Is QVeris CLI free to use?QVeris CLI 可以免费使用吗？
Install is free. Discovery and inspection are always free — zero credit cost. Credits are only consumed when you execute a live tool call (1–100 credits per call). New users get 1,000 free credits on signup with no credit card required. Credits never expire.安装免费，发现和检查也始终免费，不会消耗 Credit。只有执行实时 Tool 调用时才会消耗 Credits（每次 1–100）。新用户注册可获得 1,000 免费 Credits，无需信用卡，且 Credits 永不过期。
What's the difference between QVeris CLI and MCP Server?QVeris CLI 与 MCP Server 有什么区别？
CLI is best for terminal workflows, scripts, and agent automation pipelines — it runs as a subprocess with no schema injection overhead. MCP Server is best for IDE-embedded agents like Cursor and Claude Desktop where tool schemas need to be in the context window. Both connect to the same QVeris network — you can use both simultaneously depending on the workflow.CLI 适合终端工作流、脚本和 Agent 自动化管道，以子进程运行且没有 Schema 注入开销。MCP Server 更适合 Cursor 和 Claude Desktop 等 IDE 内嵌 Agent，因为这些场景需要 Tool Schema 进入上下文窗口。两者连接同一个 QVeris 网络，可根据工作流同时使用。
Which AI agent frameworks work with QVeris CLI?哪些 AI Agent 框架可以使用 QVeris CLI？
QVeris CLI works with any agent framework that can execute shell commands: Claude Code, OpenCode, Cursor terminal, OpenClaw, and custom agent scripts. Any framework that can run a subprocess can use QVeris CLI — there is no SDK dependency, no language-specific binding required.QVeris CLI 适用于任何能够执行 Shell 命令的 Agent 框架，包括 Claude Code、OpenCode、Cursor Terminal、OpenClaw 和自定义 Agent 脚本。只要框架能运行子进程，就可以使用 QVeris CLI；无需 SDK 依赖，也不要求特定语言绑定。
