Osmaura

Osmaura is a Y Combinator (Summer 2026) startup building opportunity intelligence for corporate law firms. It monitors public web signals, the government record, and a firm's own context to identify companies approaching a legal need before they begin looking for outside counsel, then briefs the right partner on why the moment may matter. Coverage centers on regulatory change, market movement such as hiring and funding, litigation activity, and company milestones, mapped to practice areas including immigration, startups, and commercial litigation. Osmaura ships a production REST API — the Osmaura Prospect API — documented publicly with an OpenAPI 3.1 definition. It returns dated, human-reviewed "editions" of ranked prospect dossiers that deliberately keep source-backed data separate from analyst conclusions, and every government-derived record carries an official link, a reproducible record locator, and a data-through date. Access is bearer-key authenticated, scoped to one organization, gated behind a $1,000/month plan, and reached through a private invitation link. Founded by MIT graduates Kali Abeje and Jity Woldemichael.

Osmaura publishes 1 API on the APIs.io network: Prospect API. Tagged areas include Company, Legal, LegalTech, Artificial Intelligence, and Sales Enablement.

Osmaura’s developer surface includes authentication, signup flow, support, documentation, API reference, getting-started guide, pricing, and 14 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector 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.
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/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
