AltoIRA
Alto (AltoIRA) is a Nashville-based self-directed IRA platform that lets everyday investors hold alternative assets — private equity, venture funds, startups, real estate, farmland, private credit and cryptocurrency — inside tax-advantaged Traditional, Roth and SEP retirement accounts. Alto Trust Company acts as the IRA custodian and Alto Securities, LLC (FINRA/SIPC) operates the Alto Marketplace of curated private-market offerings. Alto reports custody of roughly $2B in assets for about 30,000 self-directed IRA investors and support for more than 2,500 issuers who have raised capital on the platform. For issuers and investment platforms, Alto publishes a partner REST API (the "AltoIRA.com API") on a ReadMe developer hub that covers OAuth investor handoff, offering creation, document upload, investor invitation, investment retrieval, refunds, cancellations, distributions and capital calls, plus an investment-status webhook feed.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles AltoIRA the way a machine reads it — 19 machine-readable artifacts across 5 APIs, 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 — AltoIRA scores 53.5/100 (developing), with a separate agent-readiness read of 47/100 (agent ready). 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 AltoIRA
Each block below is one kind of artifact we hold for AltoIRA. 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.
APIs 5
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
AltoIRA Handoffs API
These are the endpoints you will redirect your investors to (these are NOT api endpoints so you cannot use the Try it out tool)
AltoIRA Investment API
The actions are performed as the manager of an offering, not as a specific user. Authentication uses the `Basic Auth` header (same as the Offering endpoints)
AltoIRA OAUTH API
Provides access to an investor's account. Generates a token to be used with the "user" endpoints below
AltoIRA Offering API
The actions are performed as the manager of an offering, not as a specific user. Authentication uses the `Basic Auth` header
AltoIRA User API
These actions are performed within the context of a specific user (uses OAuth2 with an `Authorization: Bearer` header)
Open Collections 6
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

OPEN COLLECTIONMCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVEREvent Specifications 2
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
Alto Investment Status Webhooks
Alto pushes investment-lifecycle events to a Platform Partner's registered webhook endpoint so the partner can track an investor's progress through the Direction of Investment (...

ASYNCAPISecurity 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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
OAuth scopes governing access to this provider's APIs.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of AltoIRA, 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.
