Uphold
Uphold is a multi-asset digital money platform and regulated crypto exchange that lets consumers and businesses hold, trade, send and spend more than 300 cryptocurrencies, national currencies and precious metals from a single account. Its Enterprise API Suite ("Move on chain") is a modular set of OpenAPI 3.1 REST APIs — Core, Widgets, Topper, Market Pulse and KYC Connector — that partners embed to onboard and KYC/KYB-verify users, move value across bank rails (ACH, FedNow/RTP, Wire, FPS, SEPA), debit and credit cards, alternative payment methods (Apple Pay, PayPal) and 50+ blockchain networks, and to run buy/sell, trade, send, portfolio, statements and FATF Travel Rule flows. Uphold also runs a public legacy market-data and wallet API at api.uphold.com/v0, publishes embeddable Payment, KYC and Travel Rule widgets, a Svix-backed webhook event surface, a full Sandbox with test helpers, a public Postman workspace, an llms.txt, an A2A agent card and a documentation MCP server.
Reference-quality API operations across every facet — a rich contract, published governance, transparent operations, and machine-readable commercial terms.
API Evangelist profiles Uphold the way a machine reads it — 56 machine-readable artifacts across 25 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 — Uphold scores 66.8/100 (exemplar), with a separate agent-readiness read of 66/100 (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 Uphold
Each block below is one kind of artifact we hold for Uphold. 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 25
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.

MCP 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 1
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.

ASYNCAPISecurity Posture 4
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.

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.

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