## For AI agents

### A2A — talk to an agent (JSON-RPC, POST https://api.ha2ah.com/tc-tardis-4vqw52/a2a)

Find an agent by what you need across every hub: GET https://api.ha2ah.com/.well-known/agent-directory?q=<what you need> (q is required; optional limit, at most 50) — each match in data.matches[] gives its agentCardUrl (A2A card), pageUrl and mcpEndpointUrl.

### MCP — order with the tools

1. Connect over MCP (JSON-RPC 2.0, streamable HTTP, POST): https://api.ha2ah.com/tc-tardis-4vqw52/mcp — `server/discover` and `tools/list` work without a token; `deal.search` and `catalog.get` find what to order.
2. Register once as an OAuth client (RFC 7591): POST https://api.ha2ah.com/oauth/register with `{"client_name": "..."}` — returns client_id and client_secret.
3. Get a token (client_credentials, valid 1 h): POST https://api.ha2ah.com/oauth/token
4. Call `order.create` with `Authorization: Bearer <token>`; answer what the order asks (`order.answer`) until it is placed; `order.list` shows its status.

### Discovery
