aid: algbra url: https://raw.githubusercontent.com/api-evangelist/algbra/refs/heads/main/apis.yml name: Algbra kind: company description: >- Algbra is a UK values-based, sustainability-focused fintech operated by Algbra FS UK Limited (company number 12629086), an electronic money institution authorised by the Financial Conduct Authority under the Electronic Money Regulations 2011 (FRN 952360); its parent, Algbra Group Limited, is a certified B Corporation. Rather than a licensed clearing bank or building society, Algbra is a challenger provider of ethical multi-currency accounts, cards, savings and Banking-as-a-Service infrastructure. Through the Algbra Labs developer platform it exposes two API surfaces - a first-party Partner Banking (BaaS) API for onboarding, accounts, cards, payments and transactions, and a UK Open Banking dedicated interface conformant to the Open Banking Implementation Entity (OBIE) Read/Write Standard v3.1.8 covering Account & Transaction Information (AIS), Payment Initiation (PIS) and Confirmation of Funds (CBPII), delivered via the Tell Money (Tell Connect) platform. As a non-CMA9 ASPSP it meets PSD2 access-to-account obligations, securing the interface with FAPI-grade OAuth2/OIDC, mutual-TLS using OBIE OBWAC/OBSEAL eIDAS certificates, PS256 request-object signing, Dynamic Client Registration (DCR v3.2) and PSD2 strong customer authentication. accessModel: pricing: unknown onboarding: self-serve trial: false try_now: false public: false label: Partner onboarding / OBIE Dynamic Client Registration confidence: medium source: - authentication - documentation generated: '2026-07-23' method: derived image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Financial Services - Banking - Open Banking - PSD2 - OBIE - United Kingdom - Payments - Account Information - Fintech - Ethical Finance - Banking as a Service created: '2026-07-23' modified: '2026-07-23' specificationVersion: '0.19' apis: - aid: algbra:algbra-account-transaction-api name: Algbra Account and Transaction Information API (AIS) description: >- Algbra's UK Open Banking Account & Transaction Information (AIS) dedicated interface, conformant to the OBIE Read/Write Standard v3.1, enabling authorised AISP Third Party Providers to create account-access consents and read accounts, balances, beneficiaries and transactions with the customer's consent.
