At the bottom of their “Use Cases” page, SerpApi lists the following companies and organizations as customers (“They trust us. You are in good company. Join them.”):

• Airbnb
• Nvidia
• Meta
• Shopify
• Perplexity
• KPMG
• Ahrefs
• Grubhub
• Samsung
• AI21labs
• United Nations (!)
• Thomson Reuters
• BrightLocal
• Experian

From an August 21, 2025 report in The Information (paywalled up the wazoo, alas), however:

OpenAI also isn’t the only Google rival to use SerpApi data. SerpApi’s website previously listed Apple as a customer. In addition to partnering with Google on search, the iPhone maker develops technology to power searches in Safari — a lucrative deal that the judge overseeing the DOJ case could also nix.

Was Apple removed from the list because they’re no longer (or never were?) a customer, or because they remain a customer but don’t want to be listed?
