+## Overview
+
+`haystack-spraay` provides Haystack components and tools for interacting with the [Spraay x402 Gateway](https://gateway.spraay.app) — a multi-chain batch payment protocol that lets AI agents make USDC micropayments across 16+ blockchains using the [x402 HTTP payment protocol](https://github.com/coinbase/x402).
+
+## Installation
+```bash
+pip install haystack-spraay
+```
+
+## Usage with Haystack Agent
+```python
+from haystack.components.agents import Agent
+from haystack.components.generators.chat import OpenAIChatGenerator
+from haystack.dataclasses import ChatMessage
+from haystack_spraay.tools import spraay_batch_payment, spraay_check_balance
+
+agent = Agent(
+    chat_generator=OpenAIChatGenerator(model="gpt-4o-mini"),
+    tools=[spraay_batch_payment, spraay_check_balance],
+    system_prompt="You are a blockchain payment assistant.",
+)
+
+result = agent.run(
+    messages=[ChatMessage.from_user("Check the USDC balance of 0xAd62...")]
+)
+```
+
+## Usage as Pipeline Components
+```python
+from haystack_spraay.components import SpraayBalanceCheck
+
+balance = SpraayBalanceCheck(chain="base")
+result = balance.run(address="0xAd62f03C7514bb8c51f1eA70C2b75C37404695c8")
+```
