Protego Trust Bank
Protego Trust Bank is a Seattle, Washington digital-asset trust bank built for institutional clients, offering crypto-asset custody, trading, lending/borrowing and issuer services, with custody-related fiduciary services such as staking-as-a-service, protocol governance and voting, and fork and airdrop handling. Protego Trust Company received OCC conditional approval in February 2021 to convert into a national trust bank; that approval lapsed in February 2023 after pre-conversion requirements were not met. On 13 February 2026 the OCC granted parent Protego Holdings Corporation preliminary conditional approval (Corporate Decision #1366, control number 2025-Charter-342009) to charter National Digital Trust Company, Seattle. Protego's marketing material has described API endpoints for trading and liquidity aggregation, but the company publishes no public developer portal, API reference or machine-readable contract, and as of this profile its own web properties do not complete a TLS handshake.
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.
API Evangelist profiles Protego Trust Bank 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 — Protego Trust Bank scores 1.1/100 (minimal), with a separate agent-readiness read of 3/100 (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
Protego has no reachable web surface at all - protegotrust.com, www.protegotrust.com and protegotrust.co each terminate the TLS handshake with a fatal internal_error alert and present no certificate (Webflow proxy hosts with no provisioned certificate), plain HTTP 301s into that same dead origin, api/docs/developer subdomains do not resolve, and no developer portal, API reference or spec appears at any Protego URL in the public web archive going back to 2020.
This is an honest zero, not a gap in our research. Protego Trust Bank 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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Protego Trust Bank
Each block below is one kind of artifact we hold for Protego Trust Bank. 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.
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 things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
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.

This is an independent, third-party profile of Protego Trust Bank, 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.
