How long does TTAPI store files? Where are they stored? Is persistence supported?

Storage & Persistence

TTAPI provides temporary storage for generated content. Files’ expiration times vary depending on the storage node where they are located.

Storage Domain (Host)	Expiration	Description
`https://cdn.ttapi.io`	1 month+	TTAPI’s native storage service
`https://cloudflarer2.ttapi.io`	3 days	Cloudflare R2 storage node
`https://cdn2.suno.ai` `https://delivery.eu2.bfl.ai` …	Sync with official	Original provider’s CDN, follows their official retention policy

As the platform provides temporary relay storage, please keep the following in mind to ensure your business stability:

Timely Persistence: We recommend downloading and uploading files to your own cloud storage (e.g., Aliyun OSS, AWS S3) as soon as you receive the results.
Avoid Direct Linking: Do not use the platform’s temporary file URLs as long-term access links in your production environment.
