Vercel AI SDK verifiable receipts

Install the shipped package

npm install zambo-ai-sdk ai @ai-sdk/openai zod

Published package: zambo-ai-sdk on npm.

The complete example uses the Vercel AI SDK, Zod, and its OpenAI provider. Set OPENAI_API_KEY in the model provider's runtime environment. That provider credential is separate from Zambo; the adapter calls Zambo's public endpoint without a Zambo account or key.

Wire the integration

createZamboTool(options) returns a tool for the Vercel AI SDK. Each result includes Verifiable receipt: <url> when the endpoint returns a receipt. The tool also exposes lastReceiptUrl and receiptUrls.

import { generateText, tool } from "ai";
import { openai } from "@ai-sdk/openai";
import { createZamboTool } from "zambo-ai-sdk";
import { z } from "zod";

const zambo = createZamboTool({
  description: "Run a bounded goal through the live Zambo endpoint.",
  parameters: z.object({ goal: z.string() }),
});

const { text } = await generateText({
  model: openai("gpt-5"),
  prompt: "Summarize the top story about AI agents today.",
  tools: { zambo: tool(zambo) },
});

console.log(text);
console.log("Verifiable receipt:", zambo.lastReceiptUrl);
console.log("All receipts:", zambo.receiptUrls);
