Pricing

2 credits a message.

That is the entire price list. Credits are the shared Ounie currency — one credit is one cent — and they come from the same wallet every other Ounie app draws on. No subscription, no minimum, no seats, and nothing to cancel.

With an Ounie account

2 credits

per message · $0.02 in plain money

  • Reserved before the send, settled once the provider accepts it.
  • A refused message refunds in full, pool-exact.
  • Works over REST, MCP, the dashboard and the fleet master key.

Keyless, for agents

$0.024

per message · USDC on Base, via x402

  • No account, no key, no signup. POST and you get a 402 with terms.
  • Verified before the send and settled only after it goes — an on-chain settlement is final, so a failure is caught before the money moves.
  • Send-only. A keyless caller has no account to hold an address against, so there is no inbox on this rail.

Free, forever

Anything that does not put a message on the wire costs nothing. That includes every way of being told no, which matters more here than it does on most APIs — an agent that has to pay to discover a limit will keep paying to rediscover it.

  • Reading your own send log, and every entry in it
  • Listing and filtering your sends
  • Being refused — a suppressed recipient, a tripped ceiling, a malformed message
  • A message the provider refuses (refunded in full, pool-exact)
  • Minting and revoking API keys
  • get_pricing and get_sending_policy over MCP, with no key at all

What the price carries

That part was never the product.

What money cannot buy here

The ceilings are not a plan tier.

There is no volume tier, no enterprise unlock and no way to pay for a higher recipient limit. The limits exist to protect the sending reputation that every user of this app shares, so selling exemptions from them would be selling the thing itself.
