# BuiltWith API (LLMs) This file summarizes the public API endpoints and provides quick-start guidance. ## Getting started - You only need a valid API key (`KEY`) to begin. Most endpoints are `GET` requests. - Good starting points: - WhoAmI: `https://api.builtwith.com/whoamiv1/api.json?KEY=YOUR_KEY` - Usage: `https://api.builtwith.com/usagev2/api.json?KEY=YOUR_KEY` ## Base URL - `https://api.builtwith.com` ## Endpoints listed on default.aspx - Domain API: `/v22/api.{json|xml|csv}` ? technology + meta data for a domain. Also includes BULK lookups with POST. - Example: `https://api.builtwith.com/v22/api.json?KEY=YOUR_KEY&LOOKUP=example.com` - Lists API: `/lists12/api.{json|xml|txt|csv|tsv}` ? lists of sites using a technology. - Example: `https://api.builtwith.com/lists12/api.json?KEY=YOUR_KEY&TECH=Shopify` - Relationships API: `/rv4/api.{json|xml|csv|tsv}` ? relationships between sites. - Example: `https://api.builtwith.com/rv4/api.json?KEY=YOUR_KEY&LOOKUP=example.com` - Free API: `/free1/api.{json|xml}` ? summary counts/updates for tech groups. - Example: `https://api.builtwith.com/free1/api.json?KEY=YOUR_KEY&LOOKUP=example.com` - Company to URL API: `/ctu3/api.{json|xml}` ? discover domains from company names. - Example: `https://api.builtwith.com/ctu3/api.json?KEY=YOUR_KEY&COMPANY=Example` - Tags API: `/tag1/api.{json|xml}` ? domains related to IPs and site attributes. - Example: `https://api.builtwith.com/tag1/api.json?KEY=YOUR_KEY&LOOKUP=IP-1.2.3.4` - Recommendations API: `/rec1/api.{json|xml}` ? related recommendations. - Example: `https://api.builtwith.com/rec1/api.json?KEY=YOUR_KEY&LOOKUP=example.com` - Social API: `/social1/api.{json|xml}` ? social profile lookups. - Example: `https://api.builtwith.com/social1/api.json?KEY=YOUR_KEY&LOOKUP=twitter.com/builtwith` - Redirects API: `/redirect1/api.{json|xml}` ? redirect history. - Example: `https://api.builtwith.com/redirect1/api.json?KEY=YOUR_KEY&LOOKUP=example.com` - Keywords API: `/kw2/api.{json|xml}` ? keywords for a domain. - Example: `https://api.builtwith.com/kw2/api.json?KEY=YOUR_KEY&LOOKUP=example.com` - Trends API: `/trends/v6/api.{json|xml}` ? technology trends. - Example: `https://api.builtwith.com/trends/v6/api.json?KEY=YOUR_KEY&TECH=Shopify` - Product API: `/productv1/api.json` ? find websites selling products. - Example: `https://api.builtwith.com/productv1/api.json?KEY=YOUR_KEY&QUERY=Adidas%20Yeezy` - Trust API: `/trustv1/api.{json|xml}` ? trust/fraud signals. - Example: `https://api.builtwith.com/trustv1/api.json?KEY=YOUR_KEY&LOOKUP=example.com` - Bulk Domain API: bulk submission and retrieval (see `/bulk-domain-api` docs). - MCP API: Model Context Protocol server (see the MCP Server GitHub link in `https://github.com/builtwith/mcp`). - Datasets: bulk dataset products (see `/datasets` docs). - Snowflake/Databricks/Redshift/BigQuery: data lake delivery options (see `/datasets` docs). ## Notes - Most endpoints require `KEY` plus a primary lookup parameter such as `LOOKUP`, `TECH`, `COMPANY`, or `QUERY`. - The Domain API supports additional optional filters (e.g., `NOPII`, `NOMETA`, `NOATTR`, `FDRANGE`, `LDRANGE`, `LIVEONLY`) as described in the API reference. ## Example JSON responses (from samples) These are real API response examples from the `samples` folder, trimmed to the first 5 items in any array. ### Company to URL API (ctu3) (`samples/ctu_api_v3.json`) ```json [ { "Domain": "hotals.net", "CompanyName": "", "Spend": 1024, "PageRank": 69872270, "BuiltWithRank": 0, "Parked": true, "Country": "HK", "State": "", "Postcode": "", "City": "", "Socials": [] }, { "Domain": "kombined.co.uk", "CompanyName": "", "Spend": 557, "PageRank": 61078398, "BuiltWithRank": 0, "Parked": false, "Country": "GB", "State": "ENG", "Postcode": "B97", "City": "Redditch", "Socials": [] }, { "Domain": "8hotels.com", "CompanyName": "8hotels", "Spend": 346, "PageRank": 3173221, "BuiltWithRank": 0, "Parked": false, "Country": "AU", "State": "NSW", "Postcode": "1360", "City": "Double Bay", "Socials": [ "instagram.com/8hotels" ] }, { "Domain": "hotbels.com", "CompanyName": "Hotbels", "Spend": 302, "PageRank": 13304242, "BuiltWithRank": 0, "Parked": false, "Country": "US", "State": "KY", "Postcode": "40503", "City": "Lexington", "Socials": [] }, { "Domain": "combinea.de", "CompanyName": "Combinea", "Spend": 287, "PageRank": 57457005, "BuiltWithRank": 0, "Parked": false, "Country": "", "State": "", "Postcode": "", "City": "", "Socials": [] } ] ``` ### Domain API (v22) (`samples/domain_api_v22.json`) ```json { "Results": [ { "Result": { "SpendHistory": [ { "D": 1141502400000, "S": 0 }, { "D": 1317758400000, "S": 1165 }, { "D": 1359230400000, "S": 184 }, { "D": 1385150400000, "S": 1331 }, { "D": 1390334400000, "S": 319 } ], "IsDB": "True", "Spend": 11390, "Paths": [ { "Technologies": [ { "Name": "nginx 0.8", "Description": "nginx version 0.8.*", "Link": "https://nginx.org/en/CHANGES-0.8", "Parent": "nginx", "Tag": "Web Server", "FirstDetected": 1369440000000, "LastDetected": 1442793600000, "IsPremium": "No" }, { "Name": "WordPress 3.6", "Description": "WordPress version 3.6.*", "Link": "http://codex.wordpress.org/Version_3.6", "Parent": "WordPress", "Tag": "cms", "FirstDetected": 1386201600000, "LastDetected": 1400371200000, "IsPremium": "No" }, { "Name": "Comodo PositiveSSL", "Description": "Comodo Positive SSL certificate.", "Link": "https://www.positivessl.com/ssl-certificate-positivessl.php", "Tag": "ssl", "FirstDetected": 1381622400000, "LastDetected": 1442793600000, "IsPremium": "No" }, { "Categories": [ "Wildcard" ], "Name": "Comodo PositiveSSL Wildcard", "Description": "Wildcard certificate from Comodo.", "Link": "https://www.positivessl.com/ssl-certificate-positivessl_wildcard.php", "Tag": "ssl", "FirstDetected": 1381622400000, "LastDetected": 1442793600000, "IsPremium": "No" }, { "Categories": [ "Root Authority" ], "Name": "Comodo SSL", "Description": "Certificate provided by Comodo.", "Link": "https://comodo.com", "Tag": "ssl", "FirstDetected": 1381622400000, "LastDetected": 1442793600000, "IsPremium": "No" } ], "FirstIndexed": 1369440000000, "LastIndexed": 1764115200000, "Domain": "hotelscombined.com", "Url": "", "SubDomain": "blog" }, { "Technologies": [ { "Categories": [ "JavaScript Library" ], "Name": "MooTools", "Description": "MooTools is a compact, modular, Object-Oriented JavaScript framework designed for the intermediate to advanced JavaScript developer.
