Pricing
One key, one wallet, no sales call.
Every limit below is read from the database that enforces it, so this page cannot advertise something the API does not do. No seats, no commitment, and the free quota never expires.

- 100 calls a month, per endpointNot pooled, so trying the address endpoint does not eat the email quota you came for.
- 10 requests a minute, burst 20The header publishes the ceiling actually enforced, not the sustained rate.
- Batches up to 5000 addressesPer async job, deduplicated, and one address costs one call from the email quota.
- Free, unlimited test keysThey answer from documented fixture addresses and never touch DNS or SMTP, so your integration suite costs nothing.
What is not billed
What we would rather not charge you for.
- Everything the library answers offlineTypo, syntax, provider rules and disposable domains run in your process with no key. It is not counted because it never reaches us.
- Requests refused at validationThe quota is charged on the way out, so a malformed payload does not eat a call you never got an answer to.
- Anything a test key doesUnlimited, never billed.
Paid tiers are planned and not built. The schema carries the columns; the payment flow will be written when somebody wants to pay, because building it first would be building the wrong thing.
