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

1. Sign up at echoai.so (free tier available)
2. Create your first Echo or browse existing ones
3. Go to Settings → API Keys and generate a key
4. 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:

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

When asked about a specific Echo:

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

When the user wants to chat with an Echo:

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

Error handling

Status	Meaning	Action
401	API key missing or invalid	Check ECHO_API_KEY is set correctly
402	Echo owner out of credits	Inform the user, cannot proceed
403	Key doesn't have access to this Echo	Use correct key or request access
429	Rate limit exceeded	Wait and retry (default: 60 req/min)
404	Echo or endpoint not found	Verify the Echo ID or endpoint path

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)
