Platform
API keys and wallet identity for autonomous callers.
Machine identity is how a caller proves who it is: an API key for account-based access, or a wallet address on the keyless x402 rail. Identity binds usage and spend limits to the caller.
Capabilities
What Machine Identity provides
API keys
Account callers present a key. Keys are scoped, rotatable, and attributed in usage.
Wallet identity (x402)
On the keyless rail, the paying wallet is the identity — no key to store or leak.
Per-key limits
Spending limits and rate limits attach to the identity so a compromised key is bounded.
Control cost
Spend stays bounded
- Per-key spend limits cap exposure.
- Rotate or revoke a key without touching the balance.
- Usage is attributed per identity for clean accounting.
