Zeta
Zeta is a next-generation banking and payment card processing platform for banks and financial institutions, offering a cloud-native omnistack to launch and manage credit, debit, prepaid, BNPL, and fleet card programs alongside loans and deposits. Its product suite spans Tachyon (core processing and real-time APIs and events), Neutrino (digital app experiences), Elena (conversational AI), Saturn (servicing and back-office operations), Luminos (engagement and rewards), and Zeus (data and analytics). Founded by Bhavin Turakhia and Ramki Gaddipati and backed by SoftBank Vision Fund, Zeta processes 25+ million cards across seven countries for institutions including HDFC Bank, Pluxee, and Sparrow. Zeta's platform is delivered to enterprise banking partners; its APIs are partner-gated rather than published on a public developer portal.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Zeta the way a machine reads it — 2 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Zeta scores 16.2/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Zeta
Each block below is one kind of artifact we hold for Zeta. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
