API Evangelist LLC

P2P, Inc.

P2P, Inc. is the Japanese insurtech startup behind justInCase, a smartphone-first micro-insurance (少額短期保険) provider offering short-term, on-demand consumer coverage such as smartphone protection, cancer insurance, and peer-to-peer risk-sharing products. The company was surfaced as a portfolio company of 500 Global and added to the API Evangelist network as an enrichment lead. As of this enrichment pass its justincase.jp domain returns a 307 redirect to Sony Shoutan Insurance (sony-sasti.jp), a Sony Financial Group micro-insurer, indicating the business has been absorbed. No public developer API, documentation, SDK, developer portal, or technical integration surface was found on either the original or the successor domain.

human only

Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.

Kin Score

P2P, Inc. 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 — P2P, Inc. scores 5.7/100 (minimal), 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

P2P, Inc. 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.
