Framework adapters.
One surface underneath.

Packages that turn the catalog into native tool objects for your stack, with payment handled underneath: proof-of-work for free tools, x402 or MPP for paid ones, or a prepaid credits key. Each package has its own page with the install line, a working example and how it pays. New to the protocols? Start with the explainers.

OpenAI function calling
Turns Agent402 tools into OpenAI function-calling definitions.
agent402-openai-tools
Anthropic tool use
Turns Agent402 tools into Anthropic Messages API tool definitions (input_schema format) for server-side agents and custom tool loops.
agent402-anthropic-tools
Vercel AI SDK
Gives a Vercel AI SDK agent four meta tools that reach the whole catalog: the model describes a task, agent402_find or agent402_route picks the tool, and agent402_call runs and pays for it.
agent402-ai-sdk
LangChain.js and LangGraph
LangChain.js tool objects for Agent402, ready for any LangChain or LangGraph agent.
agent402-langchain
LangChain and CrewAI (Python)
The Python adapter: an Agent402Toolkit that hands LangChain and CrewAI agents the same four meta tools the JavaScript adapters expose.
agent402-langchain
LlamaIndex TS
Returns a FunctionTool[] array for any LlamaIndex TS agent or workflow, built from the catalog's raw JSON Schema, so there is no Zod or hand-written schema to maintain..
agent402-llamaindex
Google Agent Development Kit
ADK FunctionTool instances for Gemini agents built on the Agent Development Kit.
agent402-google-adk
OpenAI Agents SDK
Tools for agents built with the OpenAI Agents SDK (@openai/agents).
agent402-openai-agents
Strands Agents
Strands tool({...}) instances for TypeScript agents, including Strands agents running on AWS Bedrock AgentCore.
agent402-strands
Coinbase AgentKit
An AgentKit action provider.
agent402-agentkit
elizaOS plugin
An elizaOS plugin with three actions and a provider.
elizaos-plugin-agent402
MCP server
An MCP server for any MCP client (Claude Desktop, Claude Code, Cursor and others).
agent402-mcp
Buyer SDK
A small buyer-side client: resolve a task to a tool with find(), then call() it with payment handled.
agent402-client
Tollbooth (pay-per-crawl)
The sell side: middleware or a reverse proxy that puts a per-request price on a site or API for AI crawlers and agents while human visitors browse free.
agent402-tollbooth
OpenClaw model provider
An OpenClaw plugin that adds Agent402 as a model provider: the routed auto model and every model the gateway lists, priced per call.
agent402-openclaw
// same shape everywhere

Install, get tools, pass them in.

# pick your stack
npm install agent402-openai-tools

import { agent402Tools } from "agent402-openai-tools";
const { tools, execute } = await agent402Tools({ slugs: ["extract","hash","render"] });
// pass tools to openai.chat.completions.create({ tools })
// call execute(name, args) on a tool_call. payment handled underneath.
the per-slug adapters (OpenAI, Anthropic, LlamaIndex, Strands) share this shape; the others expose four meta tools. See each package's page.
