# MAX_SIGNED_TRANSFORM_TTL_SECONDS

```ts
const MAX_SIGNED_TRANSFORM_TTL_SECONDS: number;
```

Defined in: packages/asset-client/dist/index.d.ts:578

The longest life a signed transform URL may claim: **7 days**.

⚠️ Must equal `MAX_SIGNED_TRANSFORM_TTL_SECONDS` on the origin
(`transform.signing.ts`), which enforces it on every verify — asking for
more here would only build a URL the platform answers 401 to, which is why
this throws instead.
