upto: settles actual usage
Compliant · POST /api/x402/upto-correct · Schemes (exact / upto / batch)
Authorizes a maximum but settles only the actual usage (~60%).
Explanation
Demonstrates correct upto behavior: the client authorizes a maximum but the server settles only the actual (lower) usage, so the buyer pays for what they used. This is the compliant baseline for metered pricing.
What to watch
settledAmount is below the authorized max.
Facilitator
Settled against the live Radius testnet facilitator (https://facilitator.testnet.radiustech.xyz). A valid payment runs a real /verify and /settle on-chain.
