Lanistar

Lanistar was a London-based consumer fintech founded in 2019 by Gurhan Kiziloz, known for a heavily influencer-marketed "polymorphic" Mastercard debit card with an on-card keypad and display that generated single-use PIN and CVV2 codes. Lanistar Limited operated as an EMD agent of Modulr FS Limited under FCA authorisation, with cards issued by AF Payments Limited, and pivoted its consumer launch to Brazil where it offered a mobile account, Pix transfers and in-app crypto buying and selling. The company never operated a developer program: no public API, developer portal, OpenAPI or other machine-readable contract, SDK, or public GitHub repository was ever published. Lanistar Limited (company number 12091938) was placed into compulsory liquidation by a court winding-up order filed 14 April 2025, and its public surface has since gone dark — lanistar.com and lanistar.app no longer resolve to any web host, the lanistar.co.uk domain is listed for sale by a domain broker, and the com.lanistar Google Play listing has been removed. This profile is retained as a historical record; there is no API surface to enrich.

Lanistar is profiled on the APIs.io network. Tagged areas include Company, Defunct, Financial Services, Fintech, and Banking.

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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

13 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 0.0 — up to +25.0 composite points
Developer Ergonomics scores 0.0 — up to +20.0 composite points
Access Clarity scores 0.0 — up to +20.0 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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. This rating is computed from the provider profile at artifacts.apis.io/lanistar/apis.yml: open an issue on github.com/api-evangelist/lanistar to ask a question or point us at an artifact you publish.

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
Brazil BCB Authorized Institutions (Banco Central do Brasil register beyond Pix)	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.

  the company. lanistar.com.br is an unrelated Brazilian influencer-marketing site ("Lanislar Creator") and is deliberately
  not wired as a Website pointer.
