Tab
Tab (tab.travel) is a London-based payment platform built specifically for independent tourism and hospitality businesses — hotels, hostels, tour operators, retreat centers and activity providers. It lets these merchants take card payments wherever their guests are, from in-advance deposits and online booking pages to in-person, on-the-move transactions via a mobile app, and to plug into an existing booking engine, PMS or OTA ecosystem. Tab natively handles 140+ currencies, pays out weekly in the merchant's local currency, and advertises transparent pricing from 2.9% per transaction with no hidden fees. Founded in 2015 by Mark Datta and backed by Y Combinator (W2015), Tab also operates a consumer-facing social-commerce guide for discovering and booking travel. This profile is maintained by the API Evangelist network; Tab does not currently publish a public developer API, SDKs or API documentation.
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.
Tab is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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 — Tab scores 17.8/100 (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.

The organization behind the API
Tab is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
