World Labs docs (captured 2026-10-23): API credits cost $1.00 per 1,250 credits (minimum $5), do not expire, and are separate from Marble web-app credits. Per world: Marble 1.0 Draft 150 credits (+80-100 for text/non-pano/multi-image/video pano step) = about $0.12-0.20; Marble 1.0/1.1 1,500 credits (+0-100) = about $1.20-1.28; Marble 1.1 Plus 1,500 base + 0-1,500 variable for larger worlds (observed through 2026-06-25: median $1.28, mean $1.71, max ~$2.48); HQ mesh export 3,500 credits (~$2.80). Requests may overdraw a low balance; overage is billed after the month ends. Docs recommend Marble 1.1 to start, Plus for the largest worlds. Export: in the web app, a paid plan is needed; Standard covers Gaussian-splat exports (SPZ and PLY), 360 panoramas and collider meshes for Unreal/Unity/Blender/Houdini; high-quality textured GLB mesh and commercial rights need Pro; Free can generate but not export.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Observed-cost statistics (median/mean/max through 2026-06-25) are as stated on the docs page.

Limitations: Web-app plan prices not captured; FAQ versions disagree on PLY via API (search snippets), not resolved here.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
