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.

TreasurySpring publishes 13 APIs on the APIs.io network, including Calendar API, Cells API, Entities API, and 10 more. Tagged areas include Company, Fintech, Cash Management, Treasury, and Investments.

The TreasurySpring catalog on APIs.io includes 1 event-driven AsyncAPI specification.

TreasurySpring’s developer surface includes authentication, sandbox, getting-started guide, engineering blog, signup flow, support, and 21 more developer resources.

scored 2026-09-08 · rubric v0.20.0
Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/treasuryspring: open an issue to ask a question, or submit a pull request to add artifacts.

  name: TreasurySpring Event Checkpoints API
  description: '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-value
    store), store the `cursor` value from `GET /event` yourself and pass it as `start_cursor` on the next request.


    **When to use checkpoints:**


    Use this endpoint if your system runs in an environment that cannot reliably persist state between invocations — for example,
    a stateless function, a script with no backing store, or a system that delegates position tracking to TreasurySpring entirely.


    A checkpoint is a named record stored server-side that remembers where your last successful sync run ended. Instead of
    storing the cursor yourself, you store it here and retrieve it at the start of each sync run:


    1. **Create** a checkpoint once: `PUT /event/checkpoint/{name}` — the cursor is initialised to the current end of the
    event stream.

    2. **Read** the checkpoint at the start of each sync run: `GET /event/checkpoint/{name}` → `cursor`, `checkpointVersion`.

    3. **Fetch events** from that cursor: `GET /event?start_cursor={cursor}`.

    4. **Advance** the checkpoint after successful processing: `PATCH /event/checkpoint/{name}` with `expectedCheckpointVersion`
    and `newCursor`. The `checkpointVersion` acts as a safety check — if another process has already advanced the checkpoint
    since you last read it, the request returns a 409 Conflict with the current state so you can reconcile before retrying.


    Checkpoints are scoped to the authenticated API user.'
