First Digital Trust
First Digital Trust Limited (trading as First Digital) is a Hong Kong-headquartered, technology-driven trust and custody institution serving the digital asset industry — blockchain startups, money service businesses, exchanges and token issuers. It provides multi-asset trust and custody across major fiat currencies, digital assets and securities, plus fiat gateways, settlement and clearing, payments rails, accounting and compliance infrastructure. It markets a developer-facing product, "Open Trust APIs" — an industry-standard RESTful API suite covering client onboarding, KYC/AML data access, account information, instruction initiation, reporting, webhooks and an SSO authentication service — but publishes no public developer portal, API reference or machine-readable specification; API access is reached through a client relationship. The firm is licensed as a Trust or Company Service Provider in Hong Kong (TC006771) and registered under section 78(1) of the Trustee Ordinance (Cap. 29), and is SOC 1 Type 2, SOC 2 Type 2 and ISO 27001 certified.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles First Digital Trust the way a machine reads it — 7 machine-readable artifacts across 1 API, 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 — First Digital Trust scores 36.8/100 (thin), with a separate agent-readiness read of 28/100 (agent aware). 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
First Digital markets "Open Trust APIs" with seven named capability areas (onboarding, KYC/AML, account information, instruction initiation, reporting, webhooks, SSO) but the product page carries no reference, no base URL, no signup and no spec — its only call to action is "Become a Client"; the client portal is Microsoft Entra sign-in and the public help center holds only end-user Client Portal articles.
An API exists — we simply could not reach the contract without credentials or a sales conversation. This one is First Digital Trust's to change: publishing the reference and a machine-readable spec at a public URL, while keeping key issuance behind whatever gate they like, would let an integrator evaluate the API before committing to a call.

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 First Digital Trust
Each block below is one kind of artifact we hold for First Digital Trust. 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 1
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.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

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.

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 First Digital Trust, 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.
