Quick start

Install the payment SDK and make a chat completion request: 
import { payer } from "@faremeter/rides";

// Load your Solana keypair
await payer.addLocalWallet(process.env.PAYER_KEYPAIR);

const response = await payer.fetch("https://openrouter.api.corbits.dev/api/v1/chat/completions", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    model: "anthropic/claude-sonnet-4-20250514",
    messages: [{ role: "user", content: "Hello from Corbits!" }],
  }),
});

const data = await response.json();
console.log(data.choices[0].message.content);

Notes

  • OpenRouter supports both OpenAI-compatible (/chat/completions) and Anthropic-compatible (/messages) request formats.
  • Model availability and pricing varies by provider. The Corbits proxy price is per-request; upstream model costs are included.
  • Payment is handled at the proxy layer via x402 — the @faremeter/rides SDK manages the challenge/response cycle automatically.
