What is Vercel AI SDK?
TypeScript toolkit for building AI-powered applications with React Server Components, streaming, and tool calling.
Searching Reddit Comments Tree with Vercel AI SDK
This integration lets your Vercel AI SDK agent search Reddit Comments Tree in real time via the Scavio API. The agent gets back structured JSON with comment text, authors, scores, depth -- 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 Reddit Comments Tree using Scavio:
import { generateText, tool } from "ai";
import { anthropic } from "@ai-sdk/anthropic";
import { z } from "zod";
// Comments are fetched per post: get a post_id from POST /api/v1/reddit/search, or resolve a URL with POST /api/v1/reddit/post. Deeper replies come from POST /api/v1/reddit/post/comments/replies using a row's reply_cursor.
const result = await generateText({
model: anthropic("claude-sonnet-4-5"),
tools: {
scavioSearch: tool({
description: "Query Reddit Comments Tree for real-time results",
parameters: z.object({ query: z.string() }),
execute: async ({ query }) => {
const res = await fetch("https://api.scavio.dev/api/v1/reddit/post/comments", {
method: "POST",
headers: {
"Authorization": "Bearer " + process.env.SCAVIO_API_KEY,
"Content-Type": "application/json",
},
body: JSON.stringify({ post_id: query, sort: "TOP" }),
});
if (!res.ok) throw new Error("Scavio API error: " + res.status);
return res.json();
},
}),
},
prompt: "t3_1u1143i",
});
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";
// Comments are fetched per post: get a post_id from POST /api/v1/reddit/search, or resolve a URL with POST /api/v1/reddit/post. Deeper replies come from POST /api/v1/reddit/post/comments/replies using a row's reply_cursor.
const result = await generateText({
model: anthropic("claude-sonnet-4-5"),
maxSteps: 5,
tools: {
scavioSearch: tool({
description: "Query Reddit Comments Tree for real-time results",
parameters: z.object({ query: z.string() }),
execute: async ({ query }) => {
const res = await fetch("https://api.scavio.dev/api/v1/reddit/post/comments", {
method: "POST",

"Authorization": "Bearer " + process.env.SCAVIO_API_KEY,
"Content-Type": "application/json",

});
if (!res.ok) throw new Error("Scavio API error: " + res.status);
return res.json();
},
}),
},
prompt: "t3_1u1143i",
});
console.log(result.text);Pricing
