- Up to 10,000 settlements per month
- No API key required
Beyond the Free Tier
Beyond the free tier, pricing is simple and predictable:Per Transaction
$0.001 per transaction
Minimum transaction amount: Transactions must be at least $0.001. This requirement will be removed after the credit system is turned on for merchants.
Builder friendly
At this pricing, the facilitator remains extremely builder friendly. It costs the same — even slightly less — than what merchants would otherwise pay in raw network fees and RPC costs, while preserving all the benefits of x402 for their users.Pricing examples
Credit System
To maintain access beyond 10,000 settlements/month, merchants log into a dashboard and top up credits.- 1 credit = 1 settled transaction
- Credits never expire
