Skip to main content
Faremeter is a collection of composable TypeScript libraries for making and accepting web3 payments over HTTP. It is built on the x402 protocol and the HTTP 402 Payment Required standard. 
pnpm add @faremeter/rides

import { payer } from "@faremeter/rides"

await payer.addLocalWallet(process.env.PAYER_KEYPAIR_PATH)
const response = await payer.fetch("https://helius.api.corbits.dev")
Faremeter handles wallet detection, payment negotiation, and settlement transparently. Your code makes HTTP requests. Faremeter handles the payments.
