aid: blink-ledger-systems name: Blink Ledger Systems description: >- Blink (Blink Ledger Systems Inc.) builds online identity and payment technologies for digital publishers. A single Blink account works across publishers, giving readers one universal login and frictionless payment so they can subscribe, donate, or buy an individual article or podcast with one click, or enable autopay for small frequent purchases. Publishers integrate three products — Blink Identity, Blink Pay and Blink Donate — through one hosted JavaScript SDK that places Blink-managed panels into the page, a dashboard-configured User Journeys rules engine, four server-side JSON endpoints for OAuth2 login, and a signed webhook notification stream covering subscription, payment and donation events. Founded 2017; incorporated in the US in 2018 and surfaced in the API Evangelist network as a Polychain portfolio company. accessModel: pricing: unknown onboarding: self-serve trial: false try_now: false public: false label: Self-serve signup confidence: medium source: - authentication generated: '2026-07-22' method: derived image: https://blink.net/resources/favicon.png url: https://raw.githubusercontent.com/api-evangelist/blink-ledger-systems/refs/heads/main/apis.yml x-type: company x-source: vc-portfolio x-backed-by: - polychain x-tier: profiled x-tier-reason: enriched-from-public-docs specificationVersion: '0.20' created: '2026-07-17' modified: '2026-07-20' tags: - Company - Infrastructure - Payments - Identity - Authentication - OAuth - Publishing - Media - Subscriptions - Donations - Micropayments - Paywall - Webhooks maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io apis: - aid: blink-ledger-systems-sdk name: Blink SDK for JavaScript description: >- Browser SDK exposing window.blinkSDK.
