Algbra

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.

Algbra publishes 16 API contracts indexed on the APIs.io network, including Accounts API, Transactions API, Automated Payments API, and 13 more. Tagged areas include Financial Services, Banking, Open Banking, PSD2, and OBIE.

The Algbra catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Algbra’s developer surface includes authentication, sandbox, getting-started guide, documentation, signup flow, engineering blog, pricing, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

6 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 50.2 — up to +12.5 composite points
Access Clarity scores 44.7 — up to +11.1 composite points
Operational Transparency scores 18.4 — up to +10.6 composite points

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
EU/EEA Payment and E-Money Institutions (PSD2 passports)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 3

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
