Stablesea
Stable Sea is a financial technology platform providing global cash management and liquidity for companies building in stablecoins. The Stable Sea Terminal lets businesses consolidate on-chain and off-chain accounts, settle money across 40+ countries, run fiat-to-stablecoin on/off-ramps for transactions up to $50M, earn yield through tokenized money-market funds, and hold Bitcoin in insured custody. The Stable Sea Terminal API is a bearer-authenticated REST API (OpenAPI 3.1) for managing organizations, liquidity providers and exchange rates, external payment instruments, offerings, quotes, and payout orders — with idempotent writes on all create operations. Surfaced as a Kindred Ventures portfolio company and enriched into the API Evangelist network.
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 Stablesea the way a machine reads it — 4 machine-readable artifacts across 2 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 — Stablesea scores 34.7/100 (thin), with a separate agent-readiness read of 17/100 (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.
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 Stablesea
Each block below is one kind of artifact we hold for Stablesea. 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 2
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.
Stablesea Liquidity Providers API
The Liquidity Providers API from Stablesea — 2 operation(s) for liquidity providers.
Stablesea Organizations API
The Organizations API from Stablesea — 11 operation(s) for organizations.
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.
