X1 was a San Francisco fintech behind the X1 Card, a smart Visa credit card that set limits based on income rather than credit score, backed by Craft Ventures. Robinhood acquired X1 in 2023 and folded the product into what is now the Robinhood Gold Card; x1creditcard.com and api.x1creditcard.com redirect to robinhood.com (probed 2026-07-21). X1 never published a public developer API, ships no SDK packages, and has no GitHub organization, so this profile records the acquisition and the domain-security posture of the remaining domain and points to the Robinhood profile in the API Evangelist network.
