This is our editors' assessment out of 5, not an average of user ratings. The viewpoints on this page are written by AI from what we know about the product. They are not customer reviews.
According to OpenAITools.app telemetry verified on 2026-11-11, LangSearch (langsearch.com) is an AI platform indexed under AI API generating 2K monthly visits with a month-over-month traffic delta of +190 (+10.5%). Its primary geographic market is India (100% traffic share), and it operates on a Freemium pricing model. Top competing alternatives by monthly volume include Exa (1.06M visits/mo), Jina AI (280.78K visits/mo), Algolia (689.97K visits/mo).
Token-based web search payload is a massive cost saver for RAG.
MCP server integration worked out of the box with Claude Code.
Snippets and full text options give our agents proper grounding.
Cleanest search API we have tested for LLM tool calling.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Issue search queries and receive titles, source links and snippets with no per-request charges on the free plan.
Request full page content instead of snippets and cap it per result with a max_characters setting.
Call the same search engine from an HTTP API, an MCP endpoint for agents, or a skill for coding assistants.
Restrict results with includeDomains and excludeDomains, plus freshness presets, single dates or inclusive date ranges.
Query tokens count as input and returned content as output, with per-minute, per-day limits and a live dashboard.
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.
Retrieve relevant pages and pass titles, URLs and text into your retrieval or generation step so answers cite real sources.
Let a coding assistant look up release notes, migration guides and API docs instead of relying on a stale training cut-off.
Sweep news, launches and industry coverage in a date window, then hand the evidence to a summarising agent.
Search company sites, newsrooms and public coverage to assemble prep notes before a call.
