# Postman > Postman is the AI-native API platform where developers and their coding agents design, test, document, govern, and distribute APIs. Agents work with Postman through the Postman CLI and agent skills, the Postman plugin for coding agents, and the Postman MCP servers. The Context Graph gives agents a live map of an organization's APIs, services, and dependencies. Postman supports HTTP, GraphQL, gRPC, MCP, MQTT, WebSocket, and other API protocols.

Technical Synthesis & Agentic Ingestion Analysis: postman.com
Automated Engineering Assessment1. HTML-to-Token Efficiency & LLM Context Window Cost
An unauthenticated HTTPS GET request to https://www.postman.com/ returns an initial HTML payload of 464.4 KB, corresponding to approximately 118,892 UTF-8 tokens when ingested raw by an AI coding agent, retrieval pipeline, or headless browser. After stripping inline <script>, <style>, <svg>, and DOM markup tags, the human-readable text footprint measures 11,040 tokens (43.1 KB)—yielding an HTML Signal-to-Noise Ratio of 9.3%.
Because postman.com publishes a valid /llms.txt manifest (measuring 5,375 tokens across 171 lines), AI retrieval agents that read /llms.txt instead of scraping the raw DOM reduce token consumption by 95.5%—cutting 1,000-read inference input costs from $148.6150 to $6.7188 at frontier model rates ($1.25/1M tokens), or $1.8813 on Gemini 4 Hydrogen ($0.35/1M).
2. Indexed Structure Inside postman.com/llms.txt
Sitecube’s specification linter verified 14 H2 section headings and 93 Markdown links inside https://postman.com/llms.txt under the primary heading "Postman".
Documented sections include: Connect a coding agent to Postman</code>, <code>Give agents access to Postman and govern AI traffic over MCP</code>, <code>Get started and choose a plan</code>, <code>Indexes</code>, <code>Look up the API reference, releases, support, and status</code>, <code>Design, build, test, and mock APIs</code>, <code>Collaborate on and distribute APIs</code>, <code>Govern and operate APIs at enterprise scale.
Key canonical endpoints referenced in the manifest include
Postman for Agents (https://www.postman.com/home.md), Postman CLI (https://www.postman.com/product/postman-cli.md), Postman plugin for coding agents (https://learning.postman.com/docs/postman-plugin/overview.md), Postman agent skills on GitHub (https://github.com/postmanlabs/postman-plugin), Context Graph (https://www.postman.com/context-graph.md).
3. Edge Delivery, TLS Handshake & Security Header Assessment
Traffic for postman.com resolves to 162.159.129.53 via Cloudflare running Next.js, achieving a measured Time to First Byte (TTFB) of 947 ms (DNS lookup: 3 ms, TCP connect: 6 ms, TLS handshake: 422 ms). The port 443 TLS certificate is issued by Let's Encrypt with 65 days remaining before expiration (valid through 2027-01-19). Outbound email authentication via SPF is present and DMARC (_dmarc.postman.com) is enforced.
