FAQ.
Straight answers about credits, accounts, limits, and how the API behaves.
What is Verinio?
Verinio is an API platform with three services: Fetch (download media from a URL), Transcript (extract YouTube captions), and Metadata (inspect, sanitize, or compress file metadata). It's built for developers, automations, and AI agents that need these as a plain HTTP call instead of self-hosted tooling.
Do I need an account to use Verinio?
Only for actions that cost credits. Any action priced at 0 credits works for anyone, signed in or not - no daily limit. The moment an action costs more than 0 credits, it requires a signed-in account with enough credits; there's no separate free-preview tier. Check current per-action pricing on pricing.
What happens if I try a paid action without enough credits?
You'll see a dialog telling you to sign in (if you're not signed in) or to buy more credits (if you're signed in but below the required amount) - either on the site or as a clear NOT_AUTHENTICATED / NOT_ENOUGH_CREDITS error from the API.
Do credits expire?
No. Credits are bought once, in a pack, and never expire. See current packs and pricing.
How do I create an account?
There's no separate signup form — buying your first credit pack creates your account automatically and signs you in. From there you can set a password on the dashboard to sign back in later.
How does API authentication work?
Every API request carries an Authorization: Bearer YOUR_API_KEY header. Your key is shown once when created and can be regenerated from the dashboard at any time — regenerating immediately disables the old key.
How is a download priced?
Fetch downloads are priced by file size — about 3.5 credits per MB, with a 5-credit minimum — because bandwidth is the real cost driver. Every other action (info lookups, transcript downloads, metadata processing) has a flat per-action cost. See current pricing or the services overview.
Am I charged if a request fails?
No. Failed requests — an unsupported URL, a missing transcript, an oversized file — are not charged.
Can AI agents use Verinio directly?
Yes — Verinio is designed for that. It's a plain HTTP API with one Bearer key and structured JSON responses, so any agent framework that can make an HTTP request can call it as a tool. See the AI agent integration guide.
What sources does Fetch support?
Fetch supports a range of common media source URLs; unsupported URLs return a clear error rather than a partial or broken download. Check a URL's support by calling the info endpoint first — failed lookups are never charged regardless.
I lost my API key. Can I recover it?
Yes — use Recover API Key with your account email, or sign in to the dashboard and generate a new one.
