const response = await fetch("https://cassandra.dropwatchhq.com/x402/pay", {

});

console.log(response.status);
console.log(Object.fromEntries(response.headers));
console.log((await response.text()).slice(0, 1000));

// A valid 402 is a quote, not a completed paid call.

This sends no payment. Inspect the 402 response before adding a wallet-enabled client.

Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
