REST/JSON API for single and batch MAC/OUI lookups, vendor directory search, and health checks. Requires a free API key via Authorization Bearer or api_key query/body. Live API at api.macadress.com: GET /v1/mac/:mac and POST /v1/mac/batch, answering 401 with an explicit "missing API key" message. Operated by ApisOS FZE. The declared apis.json 404s, but an OpenAPI 3.1.0 IS published -- at macadress.com/static/openapi.yaml?v=ceee2d51, a versioned asset path that probing the conventional locations never finds. llms.txt is served and is where the real endpoints and the MCP subdomain are named.
