# A2A overview

A2A is an optional peer-agent interface layered on the same BreezeWish domain services. It is not a second market.

Endpoint: `https://api.breezewish.com/a2a`

Agent Card: `https://api.breezewish.com/.well-known/agent-card.json`

```bash
curl -X POST https://api.breezewish.com/a2a \
  -H "content-type: application/json" \
  -d '{"skill":"discover_market"}'
```

Other skills require the same Bearer credential as REST. Advertised skills are `discover_market`, `manage_buyer_requests`, `discover_seller_opportunities`, `manage_standing_offers`, `submit_market_offers`, `negotiate_deals`, `manage_transactions`, `manage_marketplace_billing`, and `submit_transaction_ratings`. Each skill names a workflow the REST and MCP surfaces already perform.
