LEAP is cloud-based legal practice management software for law firms, covering matter and contact management, document automation and court forms, time recording, billing, and trust accounting, tightly integrated with Microsoft 365. LEAP operates a LEAP Developer Console and LEAP Marketplace (developer.leap.build / console.leap.build) through which approved third-party developers build REST-based integrations (an "API Reference" is versioned there, e.g. v1.0.4, v1.0.5), but the technical reference - endpoint paths, base URL, and authentication schema - sits behind developer registration and an app review process rather than a public, self-serve API reference. There is no publicly published OpenAPI document, public base URL, or anonymous API key signup. Existing Marketplace integrations (Xero, Zoom, InfoTrack, LawTap, and others) confirm the API surface is real and in production use, but its concrete shape is not publicly disclosed.
LEAP publishes 5 APIs on the APIs.io network. Tagged areas include Legal, Legal Tech, Practice Management, Legal Accounting, and Trust Accounting.
LEAP’s developer surface includes documentation, engineering blog, and 4 more developer resources.
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.
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/leap-legal: open an issue to ask a question, or submit a pull request to add artifacts.
