This page describes a planned direction, not shipped functionality. See Rate Limits & Quotas for the current, live access model.

​
The vision

Pay-per-call access to the API using USDC over the x402 protocol, no account, no API key, no daily quota tiers. Each request would be metered and paid for individually at the moment it’s made, directly from a wallet.

​
What’s actually live today

Access is gated by quota tiers, not payment:
  • Guest: 3 messages/network, no key.
  • Wallet-linked: 50 messages/day (UTC), via a portable ltk_ key obtained by connecting a wallet at /cli. See Authentication.
Connecting a wallet today verifies you hold a wallet in order to raise your rate limit. No funds move. The @x402/core, @x402/evm, and @x402/svm packages are present in the codebase as dependencies but are not yet wired into the inference path.
