Billing as code.

Ingest usage in one call

Events are idempotent, ordered and available for billing within milliseconds.

import Rivox from "@rivox/node";
const rivox = new Rivox(process.env.RIVOX_KEY);

await rivox.events.ingest({
  customer: "cus_acme_ai",
  event: "tokens.output",
  value: 18_420,
  timestamp: Date.now(),
});

React to billing events

Signed, versioned and retried with exponential backoff.
