What is Vercel AI SDK?
TypeScript toolkit for building AI-powered applications with React Server Components, streaming, and tool calling.
Searching Amazon Bestsellers with Vercel AI SDK
This integration lets your Vercel AI SDK agent search Amazon Bestsellers in real time via the Scavio API. The agent gets back structured JSON with products, badge, sales_volume, price -- ready for reasoning and decision-making.
Setup
Bash
npm install ai @ai-sdk/anthropic zodCode Example
Here is a complete Vercel AI SDK agent that searches Amazon Bestsellers using Scavio:
import { generateText, tool } from "ai";
import { anthropic } from "@ai-sdk/anthropic";
import { z } from "zod";
// There is no bestsellers endpoint and Amazon search takes no sort parameter, so this is the marketplace's default ranking for the query, not the Best Sellers chart. Store position per ASIN on each run to see movement.
const result = await generateText({
model: anthropic("claude-sonnet-4-5"),
tools: {
scavioSearch: tool({
description: "Query Amazon Bestsellers for real-time results",
parameters: z.object({ query: z.string() }),
execute: async ({ query }) => {
const res = await fetch("https://api.scavio.dev/api/v1/amazon/search", {
method: "POST",
headers: {
"Authorization": "Bearer " + process.env.SCAVIO_API_KEY,
"Content-Type": "application/json",
},
body: JSON.stringify({ query, country: "us" }),
});
if (!res.ok) throw new Error("Scavio API error: " + res.status);
return res.json();
},
}),
},
prompt: "electronics bestsellers",
});
console.log(result.text);Full Working Example
A production-ready example with error handling:
import { generateText, tool } from "ai";
import { anthropic } from "@ai-sdk/anthropic";
import { z } from "zod";
// There is no bestsellers endpoint and Amazon search takes no sort parameter, so this is the marketplace's default ranking for the query, not the Best Sellers chart. Store position per ASIN on each run to see movement.
const result = await generateText({
model: anthropic("claude-sonnet-4-5"),
maxSteps: 5,
tools: {
scavioSearch: tool({
description: "Query Amazon Bestsellers for real-time results",
parameters: z.object({ query: z.string() }),
execute: async ({ query }) => {
const res = await fetch("https://api.scavio.dev/api/v1/amazon/search", {
method: "POST",
headers: {
"Authorization": "Bearer " + process.env.SCAVIO_API_KEY,
"Content-Type": "application/json",
},
body: JSON.stringify({ query, country: "us" }),
});
if (!res.ok) throw new Error("Scavio API error: " + res.status);
return res.json();
},
}),
},
prompt: "electronics bestsellers",
});
console.log(result.text);Pricing
Scavio offers a free tier with 50 credits on signup (1 credit per search). No credit card required. This is enough to build and test your Vercel AI SDK integration. Paid plans start at $30/month for higher volumes.
