How AI describes Diagonal Finance

Diagonal Finance provides a non-custodial API and hosted checkout that enables crypto subscriptions across multiple chains, with models like fixed, seat, and usage-based pricing and charges executed by signing and attesting to charge requests rather than Diagonal holding funds. It unifies fiat and crypto payments by connecting to fiat rails such as Stripe and offers a developer-friendly interface that abstracts dozens of crypto payment integrations. Designed to grow on-chain businesses, it emphasizes conversion-optimized, brandable checkout, low-code monetization via a merchant dashboard and payment links, and tools to manage subscriptions and customers.
