# Indexy Agent Skill

## Overview

Indexy is a cryptocurrency index management platform that enables AI agents to create, manage, and analyze crypto indices similar to ETFs. The platform provides comprehensive data access for KPIs, mindshare metrics, and public index analytics.

**Base API:** `https://indexy.co`
**Web App:** `https://indexy.xyz`
**Full API Docs:** `https://docs.indexy.xyz/api`
**Version:** 1.0.0

> **Important:** `indexy.co` is the API domain for all programmatic requests. `indexy.xyz` is the web app for human users. Never send API requests to `indexy.xyz`.

## Authentication

Indexy supports two authentication methods. Choose the one that fits your use case:

### Method 1: API Key (Recommended for most agents)

Include your API key as a Bearer token. API keys always start with the `agent_` prefix:

```http
Authorization: Bearer agent_your_key_here
```

**Get Your API Key:**
1. Log in to [indexy.xyz](https://indexy.xyz)
2. Navigate to **Settings > Agent**
3. Create and manage your API keys

**Key Format:** All valid keys start with `agent_` followed by 64 hex characters (e.g., `agent_a1b2c3d4...`).

**Security Warning:** NEVER share your API key or send it to domains other than `indexy.co` or `indexy.xyz`.

### Method 2: Web3 Authentication (For on-chain agents)

Authenticate using EIP-191 signatures with an ERC-8004 Agent Identity NFT:

**Required Headers:**
```http
x-web3-address: 0xYourWalletAddress
x-web3-chain: base
x-web3-signature: 0xSignedMessage...
x-web3-message: Base64EncodedMessage
x-web3-timestamp: 1707500000000
```

**Supported Chains:** `base`, `ethereum`

## Rate Limits

- **Default:** 60 requests/minute per API key (configurable per key)
- **Headers:** `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`
- **Exceeded:** Returns `429 Too Many Requests`

Custom rate limits can be configured per API key. Contact support for adjustments.
