DEX & On-chain Crypto API – Liquidity, Swaps, Tokens

Are you using the free API? The standard DexPaprika API at api.dexpaprika.com is available for everyone. This Pro API is for enterprise customers who need higher performance, no rate limits, and dedicated support.

What is the Pro API?

The DexPaprika Pro API provides the same comprehensive DEX and on-chain data as our free API, but with enterprise-grade infrastructure and benefits:

No Rate Limits

Unlimited requests to support high-volume applications and data pipelines

Dedicated Infrastructure

Separate infrastructure ensuring consistent performance and availability

Priority Support

Direct access to our engineering team for technical assistance

API Key Authentication

Secure access control and usage tracking for your organization

Getting started

1. Get your API key

Pro API access requires an enterprise subscription. Contact our team to get started.

To obtain a Pro API key:

Contact Enterprise Sales

Email [email protected] to discuss enterprise options and receive your API key

2. Authentication

All Pro API requests require authentication via the Authorization header:

curl -X GET "https://api-pro.dexpaprika.com/networks/ethereum/pools" \
    -H "Content-Type: application/json" \
    -H "Authorization: api_YOUR_API_KEY_HERE"

3. API key format

Your API key will follow this format:

api_your_personal_api_key

Always prefix your key with api_ when using it in the Authorization header.

Differences from Free API

Feature	Free API	Pro API
Base URL	`https://api.dexpaprika.com`	`https://api-pro.dexpaprika.com`
Authentication	None required	API key required
Rate Limits	10,000 requests/day	No limits
Infrastructure	Shared	Dedicated
Support	Community	Priority enterprise support
Endpoints	All endpoints	All endpoints

All endpoints available in the free API are also available in the Pro API. Simply replace the base URL and add authentication.

Quick start example

Let’s fetch Solana SOL token data using the Pro API:

Prepare your request

Replace YOUR_API_KEY_HERE with your actual API key:

curl -X GET "https://api-pro.dexpaprika.com/networks/solana/tokens/So11111111111111111111111111111111111111112" \
    -H "Content-Type: application/json" \
    -H "Authorization: api_YOUR_API_KEY_HERE"

Receive the response

You’ll get the same comprehensive data as the free API:

Error handling

Authentication errors

403 Forbidden - Missing or invalid API key

Error response:

{
  "message": "Forbidden"
}

Solution: Ensure you’re including the Authorization header with a valid API key in the format api_YOUR_KEY.

401 Unauthorized - Malformed API key

Error response:

{
  "message": "Unauthorized"
}

Solution: Check that your API key follows the correct format: api_ prefix followed by your key string.

Other errors

All other error codes match the standard DexPaprika API:

400 Bad Request - Invalid parameters
404 Not Found - Resource not found
500 Internal Server Error - Server error

Available endpoints

The Pro API provides access to all DexPaprika endpoints:

Tokens

Get detailed token information including price, liquidity, and trading volume

Pools

Access liquidity pool data and trading statistics

Networks

List all supported blockchain networks

Pool Transactions

Query swap transactions, adds, and removes

Search

Search across tokens, pools, and DEXes

Batched Prices

Retrieve multiple token prices in a single request

View complete API documentation in the REST API Reference section. All examples use the free API URL - simply replace with api-pro.dexpaprika.com and add authentication.

Migration guide

Migrating from the free API to Pro API is straightforward:

Update base URL

Replace all instances of:

https://api.dexpaprika.com

With:

https://api-pro.dexpaprika.com

Add authentication header

Add the Authorization header to every request:

headers: {
  'Authorization': 'api_YOUR_API_KEY_HERE'
}

Remove rate limiting logic (optional)

Since Pro API has no rate limits, you can remove any throttling or rate limiting code from your application.

Test your integration

Make test requests to verify your API key works correctly and you’re receiving expected responses.

Best practices

Secure your API key

Never expose your API key in client-side code or public repositories.

Store API keys in environment variables or secure vaults (e.g., AWS Secrets Manager, HashiCorp Vault)
Use .env files locally and add them to .gitignore
Rotate keys periodically as part of security best practices
Never hardcode keys in your application source code

Example .env file

DEXPAPRIKA_PRO_API_KEY=api_your_personal_api_key

Monitor your API usage

Track your API usage to optimize performance and identify issues early.

Log all API requests and responses for debugging
Set up monitoring dashboards to track request volumes
Monitor response times and error rates
Alert on unusual patterns or spikes in traffic
Review usage patterns to optimize your integration

Implement robust error handling

Always handle authentication errors gracefully and implement retry logic.

Catch and handle 403/401 errors separately from other errors
Implement exponential backoff for transient failures
Don’t retry on authentication errors - fix the key instead
Log errors with context for easier troubleshooting
Provide meaningful error messages to end users

Example error handling

try {
  const response = await fetch(url, { headers });
  if (response.status === 403) {
    console.error('Invalid API key - check your credentials');
    // Don't retry - fix the key
    return;
  }
  // Handle other errors with retry logic
} catch (error) {
  console.error('Request failed:', error);
}

Use connection pooling

Reuse HTTP connections to reduce latency and improve throughput.

Configure HTTP clients to reuse connections
Set appropriate connection pool sizes (e.g., 10-50 connections)
Enable keep-alive headers
Use persistent connections for high-volume applications
Monitor connection pool metrics

Example with Python requests

import requests
from requests.adapters import HTTPAdapter

session = requests.Session()
adapter = HTTPAdapter(pool_connections=20, pool_maxsize=20)
session.mount('https://', adapter)

# Reuse session for all requests
response = session.get(url, headers=headers)
