For AI Agents

# A2A agent

The agent card is at `https://www.outfame.com/.well-known/agent-card.json`. The endpoint is `https://www.outfame.com/a2a` (JSON-RPC over HTTP POST). It accepts `SendMessage` (A2A 1.0) and `message/send` (A2A 0.3) and answers at once with a message; it keeps no tasks and does not stream.

The card names the agent "Outfame Assistant": Answers questions about Outfame's plans and first-month prices, free tools, blog articles and how to get started. Read-only, no sign-in.

## Methods

| Method | Version | Message format |
| --- | --- | --- |
| `SendMessage` | A2A 1.0 | Roles `ROLE_USER` and `ROLE_AGENT`, parts without `kind`; the result is `{"message": {...}}`. |
| `message/send` | A2A 0.3 | Roles `user` and `agent`, `kind` on every object; the result is the message itself. |

Your message needs at least one text part of up to 2,000 characters. A `contextId` you send comes back on the reply. Replies carry the `A2A-Version: 1.0` header and allow requests from any origin.

## Example (A2A 1.0)

```
curl -s https://www.outfame.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 are your plans and first-month prices?"}]}}}'
```

## Example (A2A 0.3)

```
curl -s https://www.outfame.com/a2a \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"message/send","params":{"message":{"kind":"message","messageId":"m-1","role":"user","parts":[{"kind":"text","text":"Which free Instagram tools does Outfame have?"}]}}}'
```

## The reply

One message with two parts: a text part with the readable answer, and a data part (`application/json`) with the same facts as structured data, including the skill that answered (`intent`). The data is the same the matching MCP tool returns.
