Mos
Mos is a consumer fintech that helps students find and win money for college. Founded in 2017 by Tunisian human-rights activist Amira Yahyaoui and backed by Sequoia Capital, Lux Capital and Expa, the company began as a financial-aid application service — FAFSA filing plus human advisor support — then added a fee-free student checking account and debit card in 2021. Mos shut the banking product down and cut staff in 2023 after press and investor scrutiny of its account metrics, refocusing on its original financial-aid business. The live product at mos.com is a scholarship-matching app: students swipe through awards drawn from a database the company describes as $160 billion in available funding, with college financial-planning tools and access to a personal advisor. Sequoia's own company page records Mos as acquired in 2025; the acquirer is not disclosed. Mos ships only an end-user consumer app — it publishes no developer portal, API documentation, SDK or machine-readable contract of any kind.
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.
API Evangelist profiles Mos the way a machine reads it — 1 machine-readable artifact, 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 — Mos scores 9.0/100 (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.
Why this profile is thin
Mos ships only a consumer scholarship-matching app — mos.com serves a marketing page plus four legal pages and nothing else; app.mos.com now 301s to the marketing site, and the one real API host, api.mos.com, is an AWS API Gateway that answers 403 Forbidden to every anonymous request including its root, so there is no developer portal, reference, spec or SDK to read.
This is an honest zero, not a gap in our research. Mos does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Mos
Each block below is one kind of artifact we hold for Mos. 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 1
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.

This is an independent, third-party profile of Mos, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
