Tabby

Tabby is the MENA region's largest buy-now-pay-later (BNPL) provider, founded in 2019 by Hosam Arab (ex-Namshi) and Daniil Barkalov, originally in Dubai and now headquartered in Riyadh ahead of a planned IPO. Tabby reached a $3.3B valuation in a February 2025 Series E ($160M co-led by Blue Pool Capital and Hassana Investment Company), making it the most valuable fintech in the Middle East, and reports 15M+ users, 40,000+ merchants, and $10B+ in annualized transaction volume across KSA, UAE, and Kuwait. The Tabby API powers split-purchase checkouts (Pay-in-4 interest-free, monthly plans up to 12 months), payment lifecycle management, webhooks, and dispute resolution, complemented by Tabby Card (Visa-enabled), Tabby Shop discovery, Tabby Care purchase protection, and the Tabby Plus loyalty programme. Public developer surface includes a versioned REST API across two regional hosts (api.tabby.ai for UAE/Kuwait, api.tabby.sa for KSA), an OpenAPI 3.1 specification, iOS / Android / Flutter / React Native SDKs, and certified Magento 2, Shopify, WooCommerce, Salla, Zid, OpenCart, ExpandCart, Matjrah, Salesforce, and Odoo plugins.

agent ready

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles Tabby the way a machine reads it — 26 machine-readable artifacts across 4 APIs, 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 — Tabby scores 59.2/100 (developing), with a separate agent-readiness read of 48/100 (agent ready). 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 Tabby

Each block below is one kind of artifact we hold for Tabby. 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.

APIs 4

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Tabby Checkout API

Checkout is a whole process of customer data collection and payment authorization.

Tabby Disputes API

The Disputes API is designed to simplify the process of handling disputes and help merchants resolve issues with customer orders more efficiently. Merchants can use this API to ...

Tabby Payments API

The core of tabby is a payments flow enabling you to handle payments at your webstore.

Tabby Webhooks API

Manage webhook endpoints.

Open Collections 1

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Cost, billing, and metering signals for API financial operations.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Spectral Rules 2

Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

JSON Schema 7

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Examples 5

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Example request and response payloads for these APIs.

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.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
