# UpGrow A2A agent: agent card, endpoint and example

> Index of all UpGrow pages for agents: https://www.upgrow.com/llms.txt

UpGrow's A2A agent takes a question in plain language at https://www.upgrow.com/a2a and answers at once with a text part and a data part. No key is needed.

## A2A agent

The agent card is at [https://www.upgrow.com/.well-known/agent-card.json](https://www.upgrow.com/.well-known/agent-card.json). Send JSON-RPC to `https://www.upgrow.com/a2a`. The agent answers at once with a message that holds a text part and a data part.

It handles five kinds of questions: plans and pricing, the one-time shop, free tools, blog articles, and getting started. It accepts `SendMessage` (A2A 1.0) and `message/send` (A2A 0.3).

```bash
curl -s https://www.upgrow.com/a2a \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"SendMessage","params":{"message":{"messageId":"m-1","role":"ROLE_USER","parts":[{"text":"What does UpGrow cost?"}]}}}'
```
