CommonBond
CommonBond was a New York City based financial technology lender founded in 2011 by David Klein, Michael Taormina and Jessup Shean that refinanced student loans for university graduates and originated in-school loans for MBA, law, medical and engineering students, later adding Parent PLUS refinancing and a solar/green home-improvement lending product. It raised institutional debt and equity financing, including a $35M Series B in 2015 and a $150M lending partnership with Nelnet, and operated a consumer lending platform at commonbond.co with an externally documented Postman based API at api-docs.commonbond.co. The company exited student loan refinancing in 2022 after the federal payment and interest pause removed much of the refinance market, pivoted to solar lending, and subsequently wound down. As of this profile the commonbond.co domain is parked and every path on it, including the former API documentation host, returns HTTP 410 Gone, so no public API surface remains to profile.
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.
CommonBond 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 — CommonBond scores 4.6/100 (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
CommonBond wound down after exiting student loan refinancing in 2022; commonbond.co is now a ParkingCrew "Buy this domain" holding page and every path on it — including the former Postman documented API host api-docs.commonbond.co — answers HTTP 410 Gone, and the CommonBond GitHub organization holds zero public repositories.
This is an honest zero, not a gap in our research. CommonBond 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.

The organization behind the API
CommonBond 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.
← All providers · Data indexed from github.com/api-evangelist/commonbond · machine-readable index on apis.io
This is an independent, third-party profile of CommonBond, 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.
