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

const response = await payer.fetch("https://corbits-claude.api.corbits.dev/v1/messages", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "anthropic-version": "2023-06-01",
  },
  body: JSON.stringify({
    model: "claude-sonnet-4-20250514",
    max_tokens: 1024,
    messages: [{ role: "user", content: "Hello from Corbits!" }],
  }),
});

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

Notes

  • Requests are proxied to the Anthropic API. Request and response formats match the Anthropic API reference.
  • Include the anthropic-version header in your requests as required by the Anthropic API.
  • Payment is handled at the proxy layer via x402 — the @faremeter/rides SDK manages the challenge/response cycle automatically.
