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.
