OpenZoo AI Provider for the Vercel AI SDK

Community provider for the Vercel AI SDK that gives access to OpenZoo — pay-per-call, OpenAI-compatible inference with no signup and no API key required (each request settles via x402 or card) — via its hosted endpoint (https://api.openzoo.fun/v1) or a local gateway (npx openzoo, http://localhost:8402/v1) that pays automatically from a burner wallet.

Installation

npm install openzoo-ai-provider

Setup

There is nothing to set up. OpenZoo accepts any API key — the provider defaults to the OPENZOO_API_KEY environment variable if present, and otherwise sends the literal sk-openzoo. You never need to create an account or set a variable.

Usage

import { openzoo } from 'openzoo-ai-provider';
import { generateText } from 'ai';

const { text } = await generateText({
  model: openzoo('z-ai/glm-5.3-flash'),
  prompt: 'Say this is a test',
});

console.log(text);

Streaming

import { openzoo } from 'openzoo-ai-provider';
import { streamText } from 'ai';

const result = streamText({
  model: openzoo('z-ai/glm-5.3-flash'),
  prompt: 'Write a haiku about pay-per-call inference.',
});

for await (const chunk of result.textStream) {
  process.stdout.write(chunk);
}

Local gateway

Run the local OpenZoo gateway and point the provider at it:

npx openzoo

import { createOpenZoo } from 'openzoo-ai-provider';

const openzoo = createOpenZoo({
  baseURL: 'http://localhost:8402/v1',
});

Custom configuration

import { createOpenZoo } from 'openzoo-ai-provider';

const openzoo = createOpenZoo({
  apiKey: 'sk-anything-works', // optional — any value is accepted
  baseURL: 'https://api.openzoo.fun/v1',
  headers: { 'X-Custom': 'value' },
});

Available Models

The model list is free to query at any time:

curl https://api.openzoo.fun/v1/models

z-ai/glm-5.3-flash is a good default. Any model ID returned by /v1/models can be passed as a plain string.
