Uploads and clips are kept for 7 days for live keys or 1 day for test keys, long enough to align them and fetch the clips. Clips are kept from when the job finishes, and job results stay. Voice-search audio is not kept.

See errors and retries for how to respond to a rate limit. Search is metered per request; voice search and alignment per second of audio. Pricing is on request: the account's owner asks for live access in the console, and we set up billing together.
