TreasurySpring
TreasurySpring is a digital platform for institutional cash management that helps organisations holding large excess cash balances minimise risk, maximise return and optimise time by diversifying across secure counterparties via standardised Fixed Term Funds (FTFs). Its Public API (OpenAPI 3.1) gives an authorised user programmatic access to their entities, fund cells, obligor exposures, indications, subscriptions, holdings, tasks and a normalised event stream — the full FTF lifecycle from subscription to live holding — with OAuth 2.0 auth, offset and cursor pagination, webhooks, and a published, read-only Model Context Protocol (MCP) server for AI agents.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles TreasurySpring the way a machine reads it — 32 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 — TreasurySpring scores 48.1/100 (developing), with a separate agent-readiness read of 46/100 (agent native). 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. 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 TreasurySpring
Each block below is one kind of artifact we hold for TreasurySpring. 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 13
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.
TreasurySpring Calendar API

TreasurySpring Cells API
Get information about Cells
TreasurySpring Entities API
Get information about Entities
TreasurySpring Event Checkpoints API
Server-managed cursors for stateless event stream consumers. In most cases, checkpoints are not needed. If your system can persist data locally (e.g. in a database, file, or key...
TreasurySpring Events API

TreasurySpring Holdings API
Get information about holdings. For how subscriptions become holdings and how holdings move through their lifecycle, see the FTF Lifecycle section.
TreasurySpring Indications API

TreasurySpring OAuth API
OAuth 2.0 endpoint to exchange your Client Credentials for a token. This token can then be used to access the API.

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 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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

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