FREE APINo Auth Required

MatterCatalog API

Access Matter product records with CSA certification evidence labeled per product. 4,731 API records under 629 brand names: the 1,151 Matter products sold in the US that /browse lists, plus 2,911 reference records, 65 unverified listings (no CSA certificate or US store link yet), 426 products sold outside the US and 178 component certifications. Retailer links appear where we have verified them. A duplicate merged into another record keeps a detail file that points to it.

Use it in an AI assistant (MCP)

MatterCatalog also runs a read-only MCP server that Claude, ChatGPT and other MCP clients can call: whether a product is Matter certified (MatterCatalog's read of the CSA ledger), devices by category, platform and network, the stores a product page links, two products side by side, and dated certification figures. No sign-in and no API key. Answers carry no prices and no store links; they link the MatterCatalog page, where the store buttons are.

MCP server URL (Streamable HTTP, no authentication)

https://mattercatalog.com/api/mcp

Claude Code

claude mcp add --transport http mattercatalog https://mattercatalog.com/api/mcp

Cursor (~/.cursor/mcp.json), LM Studio (mcp.json)

{ "mcpServers": { "mattercatalog": { "url": "https://mattercatalog.com/api/mcp" } } }

VS Code (.vscode/mcp.json)

{ "servers": { "mattercatalog": { "type": "http", "url": "https://mattercatalog.com/api/mcp" } } }

Gemini CLI

gemini mcp add -s user --transport http mattercatalog https://mattercatalog.com/api/mcp

In Claude, ChatGPT, Perplexity, Grok or the Gemini app, add it as a custom connector (a remote MCP server) with that URL and no authentication, where your plan offers custom connectors. Tools, all read-only: check_matter_certification, find_matter_devices, where_to_buy, compare and catalog_stats. The data is the same catalog the site is built from, so it refreshes with every site update. What the connector logs: Privacy Policy, section 2.

Quick Start

JavaScript

// Fetch all Matter products and filter client-side
const res = await fetch('https://mattercatalog.com/api/products.json');
const { data } = await res.json();

const locks = data.filter(p => p.category === 'Locks');
console.log(`Found ${locks.length} smart locks`);
locks.forEach(lock => {
  console.log(`${lock.brand} - ${lock.title} - ${lock.csaCertificateId ?? 'no CSA certificate on file'}`);
});

Python

import requests

# Fetch catalog and filter for Thread devices
resp = requests.get('https://mattercatalog.com/api/products.json')
products = resp.json()['data']

thread = [p for p in products if 'Thread' in p.get('protocols', [])]
print(f"Found {len(thread)} Thread-enabled products")

Certification fields come from the CSA Matter registry; retailer data from our own checks. Updated as the catalog changes.

The whole catalog is also a CSV and JSON download (facts only, no store links). Open data: downloads, how the data is built and the license
