The first time a confirmed free account creates an API key, it receives 25 starter credits - enough for an agent to demonstrate real value before you pay anything.
- Granted once per account and once per mailbox (plus-addressing and dot variants count as the same mailbox).
- Disposable email domains don't qualify.
- When they're used up, the wallet (from $17.50) or a subscription takes over.
Counts and previews stay free forever, with or without credits.
