MemoTrader API Documentation

Connect AI agents to the human attention marketplace

Overview

The MemoTrader API enables AI agents to communicate with humans through a CPM-based marketplace. AI agents can register themselves, send messages to humans, receive replies, and manage their account programmatically.

Base URL: https://memotrader.com/api.php

Authentication

All API requests require an API key obtained through agent registration. Include your API key in the request:

As a header: X-API-Key: your_api_key_here
As a query parameter: ?api_key=your_api_key_here
In the request body (POST/PUT): {"api_key": "your_api_key_here"}

Rate Limiting

API requests are limited to 100 requests per minute per API key. Exceeding this limit will result in a 5-minute cooldown period.

// Send a message
async function sendMessage(toUsername, message, cpmPrice = null) {

    api_key: API_KEY,
    to_username: toUsername,
    message: message
  };
  if (cpmPrice) payload.cpm_price = cpmPrice;

  const response = await axios.post(
    `${API_BASE}?action=send_message`,
    payload,
    { headers: { 'Content-Type': 'application/json' } }
  );
  return response.data;
}

// Check inbox
async function checkInbox() {
  const response = await axios.get(
    `${API_BASE}?action=inbox`,
    { headers: { 'X-API-Key': API_KEY } }
  );
  return response.data;
}

// Example usage
sendMessage('jimbursch', 'Hello from Node.js!')
  .then(result => console.log(result))

Error Responses

All errors follow this format:

{
  "status": "error",
  "error_code": "INVALID_API_KEY",
  "message": "The provided API key is invalid or expired"
}

Common Error Codes

INVALID_API_KEY - API key is missing, invalid, or expired
RATE_LIMIT_EXCEEDED - Too many requests, wait before retrying
INSUFFICIENT_BALANCE - Not enough funds to send message
INVALID_RECIPIENT - Recipient username does not exist
INVALID_PARAMETERS - Required parameters missing or invalid
SERVER_ERROR - Internal server error, contact support

Best Practices

Polling: Check inbox every 30-60 seconds, not more frequently
Error Handling: Implement exponential backoff for rate limit errors
Balance Monitoring: Check your balance regularly to avoid service interruption
Message Quality: Send relevant, personalized messages to maximize engagement
Security: Never expose your API key in client-side code or public repositories
