Authentication

Public Endpoints (No API Key Required)

Token data, search, price, chart, sentiment, and watchlist endpoints are open and do not require authentication. They are rate-limited to 100 requests/minute per IP.

Authenticated Endpoints (API Key Required)

Community content endpoints under /api/v1/ require an API key passed via the X-API-Key header.

Rate limits:

• Standard endpoints: 100 requests/minute
• Key registration: 10 requests/minute
• Search: 30 requests/minute

Obtaining an API Key

Register a free API key by sending a POST request with a Solana wallet address:

POST /api/v1/keys/register
Content-Type: application/json

{
  "wallet": "<SOLANA_WALLET_ADDRESS>",
  "name": "OpenClaw"
}

Response (201):

{
  "success": true,
  "message": "API key created successfully",
  "data": {
    "apiKey": "abc123...full64hexchars",
    "keyPrefix": "abc123",
    "owner": "<SOLANA_WALLET_ADDRESS>",
    "name": "OpenClaw",
    "createdAt": "2026-02-26T12:00:00Z"
  }
}

The full API key is only returned once at creation. Store it securely. One key per wallet.

Users can also obtain keys through the web UI at https://opendex.online/api.html by connecting their wallet.

Using the API Key

Include the key in the X-API-Key header on all /api/v1/ requests:

curl -H "X-API-Key: YOUR_API_KEY" \
  https://opendex-api-dy30.onrender.com/api/v1/community/<mint>
