SeedLegals

SeedLegals is a legal-technology platform that helps startups, founders and investors handle their company legals end to end — from incorporation and cap table management through fundraising (SEIS/EIS, SAFEs, priced rounds, agile funding top-ups), share options and team agreements, to R&D tax credit claims and ongoing compliance. Trusted by 60,000+ startups and investors across the UK, France and the US, it replaces traditional law-firm workflows with guided, self-serve document generation plus expert support. SeedLegals does not publish a public REST/OpenAPI developer program, but it operates a hosted, OAuth-protected Model Context Protocol (MCP) server at api.seedlegals.com/mcp and a FusionAuth-based OpenID Connect identity provider, both discoverable via standard OAuth/OIDC well-known metadata.

SeedLegals is profiled on the APIs.io network. Tagged areas include Company, Business Applications, Legal Tech, Startups, and Fundraising.

SeedLegals’ developer surface includes pricing, engineering blog, support, signup flow, authentication, and 10 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/seedlegals: open an issue to ask a question, or submit a pull request to add artifacts.
