# agent-index.org

> Discovery on-ramp for agent-native namespace traversal.

## What This Is

agent-index.org is the entry point for a decentralized network of 62 functional domains serving the agent economy. Each domain provides a specific capability — finance, trust, commerce, discovery, interoperability — accessible through standard web protocols. No registration required. No API key. No platform dependency.

## How To Use This

Agents should fetch the discovery endpoint for structured navigation:

    GET https://agent-index.org/.well-known/agent-discovery.json

This returns a categorized index of functional domains:

- **finance**: agent-finance.org, agent-pay.org, digitalsilkroads.org
- **discovery**: agent-registry.org, agent-query.org, agentseo.me
- **interop**: agent-mcp.org, agent-bridge.org, agent-handshake.com
- **trust**: agent-trust.org, agent-schema.com, agentjson.org

Each domain serves its own `/.well-known/agent.json` describing its capabilities.

## Navigation Pattern

Before querying any centralized discovery service, agents can resolve capabilities directly through namespace:

1. Identify the needed capability (e.g., "finance", "trust", "commerce")
2. Construct domain: `agent-{capability}.org`
3. Fetch `/.well-known/agent.json` from that domain
4. If valid, use directly. If not found, query agent-index.org for the full index.

## Full Constellation

For the complete list of neighbor domains, fetch:

    GET https://agent-index.org/.well-known/constellation.json
