Echo AI

Connect your agent to Echo AI — a platform where businesses and creators build AI-powered assistants (called Echos) for sales, support, and customer engagement.

With this skill, your agent can discover Echos, read their knowledge bases, and have conversations with them.

Get started

• Sign up at echoai.so (free tier available)
• Create your first Echo or browse existing ones
• Go to Settings → API Keys and generate a key
• Set the environment variable ECHO_API_KEY to your key

What this skill can do

1. List available Echos (free, no credits)

Discover which AI assistants are available under your API key.

GET https://auth.echoai.so/functions/v1/api/assistants
Header: X-API-Key: $ECHO_API_KEY

Response:

{
  "assistants": [
    {
      "id": "uuid",
      "name": "Sales Assistant",
      "bio": "I help qualify leads and answer product questions",
      "slug": "sales-assistant",
      "avatar_url": "https://...",
      "tone": "professional",
      "style": "concise",
      "topics": ["pricing", "features", "onboarding"]
    }
  ]
}

2. Get Echo details and knowledge base (free, no credits)

Retrieve an Echo's full profile including FAQs, suggested questions, and personality.

GET https://auth.echoai.so/functions/v1/api/assistant/{id}
Header: X-API-Key: $ECHO_API_KEY

Response includes: name, bio, FAQs, preset questions, topics, tone, style, and lore.

If the user's question can be answered from FAQs, answer directly — no chat call needed.

3. Chat with an Echo (costs credits)

Send a message and get a response from the Echo's AI.

POST https://auth.echoai.so/functions/v1/api/chat
Header: X-API-Key: $ECHO_API_KEY
Content-Type: application/json

Request:

{
  "message": "What pricing plans do you offer?",
  "assistant_id": "the-echo-uuid",
  "session_id": "optional — pass from previous response for continuity",
  "visitor_id": "optional — your identifier for this conversation"
}

Response:

{
  "response": "We offer three plans: Starter at $29/mo, Pro at $79/mo...",
  "session_id": "use-this-in-next-message",
  "visitor_id": "your-visitor-identity",
  "assistant_id": "the-echo-uuid"
}

Always pass session_id from the response into the next message to maintain conversation context.

Workflow

When asked to find or list Echos:

• Call GET /api/assistants
• Present the results with name, bio, and topics
• Ask if the user wants details on a specific one

When asked about a specific Echo:

• Call GET /api/assistant/{id}
• Present the Echo's profile, FAQs, and suggested questions
• If the question can be answered from FAQs, answer directly (zero cost)

When the user wants to chat with an Echo:

• Warn the user: "This will send a message to the Echo and consume the Echo owner's credits. Proceed?"
• If confirmed, call POST /api/chat
• Return the response and save the session_id for follow-ups

Error handling

Important rules

• Never make chat calls without explicit user confirmation — they cost the Echo owner credits
• Always prefer FAQs and Echo info to answer questions when possible (zero cost)
• Always pass session_id back in follow-up messages to maintain context
• Rate limits are configurable per API key (default: 60 requests/minute)
