## Overview

LangSearch is an API-first web search layer for AI applications. Instead of bolting a scraping pipeline onto your agent, you issue one search request and receive structured results — titles, source links, snippets, dates, and optionally the full text of each page up to a configurable character limit. Because the payload is measured in tokens rather than requests, you control how much context each answer consumes, and the same allowance covers both API calls and MCP calls.

Integration is deliberately broad. LangSearch exposes a conventional HTTP API for backend code, an MCP endpoint for agent frameworks, and a skill format for coding assistants, with copy-paste setup snippets published for Codex, Claude Code, Cursor, VS Code, Gemini CLI, OpenCode, Windsurf, Cline, Roo Code and Zed. Filters include domain inclusion and exclusion, freshness presets, exact dates or date ranges, and up to 50 results per request.

The commercial pitch is radical simplicity: every supported search feature is included in the free plan, input and output token prices are currently listed at $0, and there are no per-request fees or feature add-ons. A daily token allowance applies and resets at 00:00 UTC; new accounts start at about 5 requests per second with per-minute and per-day token limits visible in the dashboard. For enterprises, the site advertises SOC 2 Type II audit, zero data retention options, GDPR-aligned handling and a 99.99% availability SLA, with a separate route to contact the team.

## Pricing & Plans

Free plan with all web search features included, $0 listed input/output token pricing, daily token allowance resetting at 00:00 UTC, and roughly 5 requests per second for new accounts. Enterprise security and SLA options are available by contacting the team.

## Key Features & Capabilities

- **Free web search API:** Issue search queries and receive titles, source links and snippets with no per-request charges on the free plan.
- **Full webpage text:** Request full page content instead of snippets and cap it per result with a max_characters setting.
- **MCP, Skill and REST access:** Call the same search engine from an HTTP API, an MCP endpoint for agents, or a skill for coding assistants.
- **Domain and date filtering:** Restrict results with includeDomains and excludeDomains, plus freshness presets, single dates or inclusive date ranges.
- **Token-based usage control:** Query tokens count as input and returned content as output, with per-minute, per-day limits and a live dashboard.

## Primary Use Cases

- **Ground RAG answers in fresh sources (LLM app developer):** Retrieve relevant pages and pass titles, URLs and text into your retrieval or generation step so answers cite real sources.
- **Ship against current documentation (Coding agent user):** Let a coding assistant look up release notes, migration guides and API docs instead of relying on a stale training cut-off.
- **Build sourced market briefs (Research analyst):** Sweep news, launches and industry coverage in a date window, then hand the evidence to a summarising agent.
- **Prepare account intelligence (Sales engineer):** Search company sites, newsrooms and public coverage to assemble prep notes before a call.

## Strengths

- All supported search features are bundled into a free plan with no per-request add-ons
- Three integration paths — REST API, MCP server and agent skill — cover most agent stacks
- Token metering plus domain and date filters give fine control over context size and relevance
- Enterprise posture includes SOC 2 Type II audit, zero data retention options and an availability SLA

## Limitations

- Large or frequent workloads are governed by a daily token allowance rather than truly unlimited throughput
- New accounts are rate limited to roughly 5 requests per second initially
- Free-tier figures such as $0 token pricing are current published rates and can change

## Frequently Asked Questions

### Is the LangSearch web search API really free?
The published plan makes web search and its supported features free, including snippets, full webpage text, domain and date filtering and up to 50 results per request. A daily token allowance applies, so free does not mean infinite throughput.

### How is usage measured?
Each successful search counts the query as input tokens and the returned search content as output tokens. Metadata such as titles and URLs is excluded. Limits are expressed per minute and per day, and the dashboard shows tokens used plus the next reset.

### Can I get full text instead of snippets?
Yes. Set the contents text option to true to receive page text rather than a snippet, with a default cap of around 5,000 characters per result, or supply your own positive max_characters value. There is no extra feature fee, but returned text consumes your token allowance.

### How do I connect it to an AI agent?
Use the MCP endpoint or the published skill configuration alongside the REST API. Setup snippets are provided for Codex, Claude Code, Cursor, VS Code, Gemini CLI, Windsurf, Cline, Roo Code and Zed, and all of your keys and MCP calls share one allowance.
