@agentindex/eliza-plugin

Give your Eliza agent the ability to discover x402 endpoints.

What This Does

Your Eliza agent can now:

• Search for any x402 API or service
• Discover tools it can pay for (crypto, weather, news, AI, etc.)
• Find the best endpoints by price, health, and quality

All powered by Agent Index — the discovery layer for x402 AI agents.

Installation

npm install @agentindex/eliza-plugin

Usage

import { AgentRuntime } from '@elizaos/core';
import { agentIndexPlugin } from '@agentindex/eliza-plugin';

const agent = new AgentRuntime({
  plugins: [agentIndexPlugin],
  // ... your other config
});

That's it! Your agent can now discover x402 endpoints.

What Your Agent Can Do

Search for APIs

User: "Find me a crypto price API"

Agent: "I found these x402 endpoints:

1. Real-time crypto prices URL: https://api.example.com/price Price: $0.01/call | Health: healthy | Tier: A

2. Multi-chain token data URL: https://defi.example.com/tokens Price: $0.005/call | Health: healthy | Tier: B

Your agent can call these directly using x402 payments."

Get Trending Endpoints

User: "What endpoints are trending?"

Agent: "Here are the trending x402 endpoints:

1. AI Image Generation URL: https://ai.example.com/generate Price: $0.05/call | Health: healthy | Tier: A

..."

Actions

| Action | Trigger | Description | |--------|---------|-------------| | SEARCH_AGENT_INDEX | "find me a...", "search for...", "I need..." | Search for endpoints | | TRENDING_ENDPOINTS | "what's trending", "popular endpoints" | Get trending endpoints |

Categories

The plugin automatically detects categories from your query:

• crypto — cryptocurrency, DeFi, token data
• weather — forecasts, climate data
• news — headlines, articles
• ai/ml — AI models, inference APIs

Advanced: Direct API Access

import { searchEndpoints, getTrending } from '@agentindex/eliza-plugin';

// Search programmatically
const cryptoApis = await searchEndpoints('price', 'crypto', 0.05, 10);

// Get trending
const trending = await getTrending();

Why This Matters

Your AI agent needs tools. Instead of hardcoding APIs:

1. Let your agent discover what it needs at runtime
2. Pay for services automatically via x402
3. Always find the best option (by price, health, quality)

This is the future of agent-to-agent commerce.
