For teams shipping agents into production

Give your AI agent infinite tools with one API call

Stop wiring one-off endpoints for every capability. Anytool turns prompts into reusable tools running in isolated Bun containers. Generated in seconds, cached forever, with per-user keys and per-tool state.

10 free generations/month • 1,000 runs/month See it work live →

Add one meta-tool, get a growing library of tools

Integrates with any LLM framework. The mental model: each tool is just (input) => Promise<output> your agent can call.

Vercel AI SDK Example

import { generateText, tool } from 'ai'
import { openai } from '@ai-sdk/openai'
import { z } from 'zod'

const anytool = tool({
  description: 'Generate, cache, and run tools on demand',
  parameters: z.object({
    prompt: z.string(),
    input: z.string()
  }),
  execute: async ({ prompt, input }) => {
    const res = await fetch('https://anytoolhq.com/api/tool', {
      method: 'POST',
      headers: { 
        'Authorization': `Bearer ${process.env.ANYTOOL_KEY}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({ prompt, input })
    })
    return res.json()
  }
})

// Your LLM now has a personal tool library
await generateText({
  model: openai('gpt-5'),
  tools: { anytool },
  prompt: 'Generate a QR code for https://example.com'
})

Works with AI SDK, LangChain, or any LLM framework. See docs →
