World Labs announces the World API

What to verify next

The World Labs announcement and current documentation should be checked for endpoints, access requirements, supported inputs, output formats, rate limits, and examples. Do not assume that every Marble capability is exposed through the API unless the docs say so.

Limits before overclaiming

An API direction is not the same as a mature public platform. Keep the page anchored in documented access and avoid overstating stability, pricing, or production readiness.

Do not imply every Marble capability is already exposed as a stable general API.

How to use this signal

Read this update as a change to World API, Marble, not as a standalone verdict on the whole market. The stable dossier keeps the slower facts: organization, access, source trail, strengths, and limitations. The release signal records the narrower event and points readers toward the page that should remain useful after the news cycle moves on.

If the update affects a comparison path such as HY-World 2.0 vs Marble, Genie 3 vs Marble, use that guide for the practical decision. The source list below is kept on the page so readers can verify the claim directly, check whether access has changed, and avoid repeating a stronger capability statement than the cited material supports.
