Juniper Square

Juniper Square is a fund operating system for the private markets, used by 2,300+ general partners across private equity, venture capital, commercial real estate, and private credit to raise capital, run fund administration and fund accounting, and manage the LP experience. Its GPX platform unifies investor data, fund accounting, payments, compliance, and reporting, and exposes them through a developer API (broad read/write coverage delivered as a developer-led engagement), pre-built connectors (HubSpot, Preqin, Outlook, DocuSign, Yardi IM/Voyager, Lob), and Headless GPX — an MCP server that brings the platform to any MCP-compatible AI client (Claude, Copilot, ChatGPT, Gemini) with authentication, permissions, and audit inherited from the customer's existing configuration.

Juniper Square is listed with 1 API on the APIs.io network. Tagged areas include Company, Investment Management, Private Markets, Fund Administration, and Fund Accounting.

Juniper Square’s developer surface includes getting-started guide, engineering blog, documentation, and 19 more developer resources.

scored 2026-10-31 · rubric v0.25.0
Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
  • Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
  • Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
  • Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
  • A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
  • Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
  • Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

Kin Score — facets with the most composite points still available (weight × headroom):
Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.
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 the provider profile at artifacts.apis.io/junipersquare/apis.yml: open an issue on github.com/api-evangelist/junipersquare to ask a question or point us at an artifact you publish.
