## LangSearch

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.

- **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.

**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

## OpenAI Platform

While ChatGPT serves end users, openai.com and the OpenAI Developer Platform (developers.openai.com) provide the foundational API, SDKs, and enterprise infrastructure powering thousands of production AI applications worldwide. In late 2026, OpenAI's API catalog is anchored by the GPT-6 and GPT-6.1 model suite—all featuring a 1.05-million-token context window and up to 128K output tokens. The lineup spans GPT-6 Astra for frontier reasoning and mission-critical research, GPT-6.1 Sol for near-Astra intelligence at one-fifth the price, GPT-6.1 Terra for fast visual reasoning and computer use, and GPT-6 Luna for ultra-high-volume, low-latency tasks, alongside specialized models like `gpt-5.3-codex` and `gpt-6-astra-law`.

The OpenAI Platform has evolved well beyond basic chat completion endpoints. Through the unified `v1/responses` API, developers can orchestrate stateful multi-step agents equipped with built-in server-side tools—including live web search, vector file search, code interpreter sandboxes, and GUI computer use—without stitching together external orchestration frameworks. Every flagship model supports configurable reasoning effort (`none`, `low`, `medium`, `high`, `xhigh`, and `max`), strict JSON schema Structured Outputs, and multimodal image/audio inputs, while `gpt-live-1` powers per-second billed speech-to-speech voice agents.

OpenAI bills API usage on a transparent consumption model scaled across usage tiers (Build, Launch, and Grow, scaling up to 40M+ tokens per minute). In 2026, aggressive price cuts on the 6.x generation dropped entry-level intelligence on GPT-6 Luna to $0.10 per million input tokens and $0.50 per million output tokens, while GPT-6.1 Sol runs at $2/$10 and flagship GPT-6 Astra sits at $10/$50. Engineering teams can cut spend by 90% on repeated context using automatic Prompt Caching, save 50% on asynchronous workloads via the Batch API, and enforce regional data residency with a 10% compliance uplift.

**Pricing & Plans:** Usage-based pay-per-token API billing: GPT-6 Astra at $10/1M input and $50/1M output tokens; GPT-6.1 Sol at $2/1M input and $10/1M output; GPT-6.1 Terra at $1/1M input and $5/1M output; GPT-6 Luna at $0.10/1M input and $0.50/1M output; GPT-Live-1 voice at $0.05/minute; 90% discount on cached inputs and 50% off via Batch API.

- **GPT-6 & GPT-6.1 Model Lineup with 1.05M Context:** Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
- **Configurable Reasoning Effort Controls:** Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
- **Responses API & Native Computer Use Tools:** Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
- **GPT-Live-1 Realtime Voice API:** Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
- **90% Prompt Caching Discount & Batch API:** Cached input tokens bill at just 10% of standard input rates, while asynchronous 24-hour Batch API jobs cut both input and output token costs by 50%.

**Strengths:** 100-fold cost flexibility from GPT-6 Luna ($0.10/$0.50 per 1M tokens) up to frontier GPT-6 Astra ($10/$50 per 1M tokens); Unified 1.05M-token context window and 128K output limit across the entire flagship GPT-6 and GPT-6.1 family; 90% discount on cached input tokens and 50% Batch API discount dramatically reduce production inference bills; Industry-standard SDKs, Structured Outputs, and built-in Responses API tools minimize boilerplate agent code

**Limitations:** Long-context requests exceeding the standard window threshold trigger roughly 2x higher per-token billing rates; Flagship GPT-6 Astra ($10 input / $50 output per 1M tokens) is significantly more expensive than Claude Opus 5.5 ($4/$20) and Grok 4.7 ($2/$6); Regional data residency endpoints incur a 10% price uplift on models released after March 2026
