Native API responses
Every versioned public fixture returned a timestamped native transcript in production.
YouTube transcript reliability, measured in public.
The September 3, 2026 production run covers 200 public videos selected for caption metadata. It measures HTTP response success with shared cache enabled. It does not measure arbitrary-video coverage or transcript accuracy.

Production results
Run on 3 September 2026 with deployment 6ead6a6. Generated work is covered by separate end-to-end fixtures.
200 / 200
Observed latency
The run mixed shared-cache responses with uncached extraction at three concurrent workers.
Generated transcript
A captionless public fixture completed through download, processing and persistence.
Native isolation
Native extraction remained available while the generated worker was active.
Reproduce the method.
The methodology defines the video categories, cache rules, latency measurement and exclusions. The current aggregate result is available without republishing transcript content.
