Nesto
Nesto Inc. is a Montreal-headquartered Canadian digital mortgage lender and mortgage technology provider, founded in 2018 and licensed across Canadian jurisdictions. It sits on the financing side of the residential real estate value chain rather than the listings side — originating, underwriting, and servicing mortgages direct-to-consumer at nesto.ca, and, following its 2024 acquisition of CMLS Group, administering roughly CA$73 billion in residential and commercial mortgage assets. Its Nesto Cloud business (nestocloud.ca) sells the same origination, underwriting, and servicing platform to banks, credit unions, and commercial lenders as SaaS or fully outsourced BPO, and advertises "seamless API integrations with your existing systems and third-party providers" alongside a Maestro AI underwriting engine. That API surface is not publicly documented: there is no developer portal, no published reference, no OpenAPI or other machine-readable contract, and no self-serve signup. Access is a commercial engagement negotiated with the Nesto Cloud team. As a mortgage lender Nesto sits outside the listings syndication layer entirely — no RESO Web API or Data Dictionary certification, no RESO UPI usage, and no CREA Data Distribution Facility participation is published or discoverable. The company's only machine-readable public artifact is a security.txt whose disclosure scope explicitly names "Web applications, APIs, and customer-facing services", confirming APIs exist while none are documented for outside developers. Its compliance posture is, by contrast, published and audited — SOC 1 Type II, SOC 2 Type II and ISO 27001:2022 with a Vanta trust center — and its GitHub organization (nestoca) ships MIT-licensed developer-platform tooling such as the joy GitOps CLI, though no client SDK for any Nesto service.
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.
API Evangelist profiles Nesto the way a machine reads it — 3 machine-readable artifacts, 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 — Nesto scores 26.9/100 (emerging), with a separate agent-readiness read of 7/100 (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.

How we profile Nesto
Each block below is one kind of artifact we hold for Nesto. 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 3
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.
