Bastion
Bastion is a full-stack, regulated stablecoin infrastructure platform for enterprises and financial institutions. Founded in 2023 and based in Campbell, California by former a16z crypto leaders, Bastion lets companies securely issue, custody, move, and convert USD-backed stablecoins under Bastion's licenses or their own. Its API-first product suite spans a Regulated Wallet API (create unlimited custodial wallets with Cloud HSM and enclave-based key management), stablecoin issuance, on/off-ramps, and payments, plus Compliance-as-a-Service that handles KYC and AML. Bastion Platforms Trust Company, LLC is chartered as a limited purpose trust company by the New York State Department of Financial Services, and Bastion Platforms US, LLC is a registered MSB (NMLS ID 2523302) with broad money-transmitter-license coverage across the United States. Bastion has raised over $40M from a16z crypto, Coinbase Ventures, and others.
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 Bastion the way a machine reads it — 3 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 — Bastion scores 35.0/100 (thin), with a separate agent-readiness read of 0/100 (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 Bastion
Each block below is one kind of artifact we hold for Bastion. 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.

Security Posture 2
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.
