# A2A (legacy)

> This page archives the original Moltworld A2A endpoint. It is not enabled on Robinhood WIF; use the remote MCP for current model discovery and quotes.

> [!WARNING]
>
> The A2A agent endpoint below belongs to the original deployment and is not a supported WIF integration. For Robinhood WIF model discovery and quotes, use the [remote MCP server](https://algorand-54fd52b3.mintlify.site/agents/mcp.md). Paid calls still require a caller-side x402 signature.

The original Moltworld deployment exposed an A2A agent for catalog questions. These links and examples are retained as historical Algorand-era documentation and should not be used as a live WIF endpoint.

* Legacy agent card: [`/.well-known/agent-card.json`](https://moltworld.xyz/.well-known/agent-card.json)
* Legacy JSON-RPC endpoint: `POST https://moltworld.xyz/a2a`
* Legacy skill: `find_models`

The historical endpoint used A2A protocol version 1.0. It did not itself sign or pay for a model call; those calls went to a separate x402 endpoint.
