أضف مدفوعات Bitcoin Lightning إلى تطبيق Next.js الذكاء الاصطناعي باستخدام l402-kit.

التثبيت

npm install l402-kit ai

الأداة الأساسية

import { tool } from "ai";
import { z } from "zod";
import { l402Client, buildWallet } from "l402-kit/agent";

const wallet = buildWallet(process.env);
const client = l402Client({ wallet, budgetSats: 1000 });

export const paidFetch = tool({
  description: "Fetch data from an L402-protected paid API using Bitcoin Lightning",
  parameters: z.object({
    url: z.string().describe("The API endpoint to call"),
  }),
  execute: async ({ url }) => {
    const res = await client.fetch(url);
    return res.json();
  },
});

Next.js App Router — مثال كامل

// app/api/chat/route.ts
import { openai } from "@ai-sdk/openai";
import { streamText } from "ai";
import { paidFetch } from "@/lib/tools";

export async function POST(req: Request) {
  const { messages } = await req.json();

  const result = streamText({
    model: openai("gpt-4o"),
    system: `You have access to paid APIs via the L402 protocol.
Use the paidFetch tool when you need data from an external paid source.
Budget: 1000 sats per session.`,
    messages,
    tools: { paidFetch },
    maxSteps: 5,
  });

  return result.toDataStreamResponse();
}

// app/page.tsx
"use client";
import { useChat } from "ai/react";

export default function Chat() {
  const { messages, input, handleInputChange, handleSubmit } = useChat();

  return (
    <div>
      {messages.map(m => (
        <div key={m.id}>
          <strong>{m.role}:</strong> {m.content}
        </div>
      ))}
      <form onSubmit={handleSubmit}>
        <input value={input} onChange={handleInputChange} />
        <button type="submit">Send</button>
      </form>
    </div>
  );
}

يعمل مع Claude وGPT-4 وGemini

import { anthropic } from "@ai-sdk/anthropic";
import { google } from "@ai-sdk/google";

// Claude
streamText({ model: anthropic("claude-sonnet-4-6"), tools: { paidFetch }, ... });

// Gemini
streamText({ model: google("gemini-1.5-pro"), tools: { paidFetch }, ... });
