## Agent API

This site exposes a live A2A (Agent2Agent) endpoint that speaks JSON-RPC 2.0 — agents can get quotes and submit requests without scraping the page.

- `GET /.well-known/agent-card.json` — A2A Agent Card (capabilities and skills)
- `POST /api/a2a` — JSON-RPC 2.0, method `message/send`
- Skills: `get_instant_quote`, `estimate_print_time`, `recommend_material`, `service_information`, `submit_quote_request`

Every main page also supports content negotiation: send `Accept: text/markdown` or `Accept: application/json` to receive a machine-readable version instead of HTML.

## Examples

```bash
# Discover the agent
curl https://g3dkprinting.au/.well-known/agent-card.json

# Get an instant quote (JSON-RPC 2.0)
curl -X POST https://g3dkprinting.au/api/a2a \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"message/send","params":{"message":{"role":"user","parts":[{"kind":"data","data":{"skill":"get_instant_quote","params":{"material":"petg","length":50,"width":50,"height":80,"infill":20}}}]}}}'
