Longbridge Developers platform expert. Use when: (1) querying market data or executing trades via CLI (`longbridge` command), (2) writing Python/Rust programs using the `longbridge` SDK, (3) configuring the Longbridge MCP server for AI tools (Cursor, Claude Code, ChatGPT), (4) integrating Longbridge docs into LLM/RAG systems via llms.txt or Markdown API. Covers all markets: HK, US, CN (SH/SZ), SG, Crypto. Triggers on `longbridge` imports, stock symbols (TSLA.US, 700.HK), API key setup, order placement, WebSocket subscriptions, or any Longbridge platform capability question.

Longbridge Developers Platform

Full-stack financial data and trading platform: CLI, Python/Rust SDK, MCP, and LLM integration.

Official docs: https://open.longbridge.com llms.txt: https://open.longbridge.com/llms.txt

First-Time Setup

Before using any Longbridge feature, check which tools are available:

CLI — run

longbridge --version

to check. If not installed:

bash

# macOS
brew install --cask longbridge/tap/longbridge-terminal

# Any platform
curl -sSL https://github.com/longbridge/longbridge-terminal/raw/main/install | sh

Then authenticate:

bash

longbridge login

MCP (for AI tools) — if the user wants to query data or trade directly inside the AI chat (without writing code), add the hosted MCP server:

bash

# Claude Code
claude mcp add longbridge https://openapi.longbridge.com/mcp

First tool call triggers an OAuth browser flow. See references/mcp.md for other clients (Cursor, ChatGPT, Zed).

Authentication Overview

Method	Credential	Best for
OAuth 2.0 ⭐	`client_id` only, no secret	CLI, SDK scripts, MCP
API Key	`APP_KEY` + `APP_SECRET` + `ACCESS_TOKEN`	Legacy / server-side

OAuth token cache:

~/.longbridge/openapi/tokens/<client_id>

Register OAuth client: POST

https://openapi.longbridge.com/oauth2/register

Rate Limits

REST API: max 10 calls/second
SDK auto-refreshes OAuth tokens
WebSocket subscriptions: subject to quote package limits
