This guide will walk you through everything you need to get started with Dune’s APIs, from creating an API key to making your first request.

​
1. Sign Up

Create your account at dune.com/auth/register New accounts come with free credits to get you started.

​
2. Generate API Key

  1. Navigate to API settings page
  2. Click Create API Key
  3. Give your key a descriptive name (e.g., “Production API”, “Development”)
  4. Copy and securely store your API key
  • Dune has two types of account: user account and team account. A team can have many users. A user can join many teams.
  • Each user or team account has its own context. Queries created under a team account can only be managed within the team account context.
  • An API key belongs to a specific context, and is either associated with a user account or a team account.
Keep your API key secure! Treat it like a password. Never commit it to version control or share it publicly. Anyone with your API key can make requests on your behalf and consume your credits.

​
3. Authenticate

Use your API key to authenticate requests to Dune’s APIs. Include it in your request headers: 
X-DUNE-API-KEY: your-api-key-here

​
Initialize the SDK

from dune_client import DuneClient

# DuneClient will read the DUNE_API_KEY environment variable
dune = DuneClient()
Best practices:
  • Store API keys in environment variables
  • Create separate keys for development and production
  • Rotate keys periodically
  • Revoke keys immediately if compromised

​
4. Start Building

Use your API key to make requests to Dune’s APIs. Here’s a simple example to get recent DEX trades: 
# Execute a SQL query
curl -X POST "https://api.dune.com/api/v1/sql/execute" \
  -H "Content-Type: application/json" \
  -H "X-DUNE-API-KEY: YOUR_API_KEY" \
  -d '{
    "sql": "SELECT * FROM dex.trades WHERE block_time > now() - interval '\''1'\'' day LIMIT 10",
    "performance": "medium"
  }'

​
Understanding the Response

The API returns an execution object with your query status: 
{
  "execution_id": "01K9AHMWSJZD59KAGB3WY45895",
  "state": "QUERY_STATE_EXECUTING",
  "submitted_at": "2025-11-05T17:39:48.146829Z",
  "expires_at": "2026-02-03T17:39:48.329665Z"
}
Queries execute asynchronously. Use the execution_id to check status and retrieve results. Our SDKs handle polling automatically.

​
Getting Results

Once execution completes, fetch the results: 
curl "https://api.dune.com/api/v1/execution/{execution_id}/results" \
  -H "X-DUNE-API-KEY: YOUR_API_KEY"

​
Next Steps

Now that you’ve made your first request, explore common use cases:

Analyze onchain data

Build custom analytics pipelines and reports

Use connectors

Connect with Trino Connector or DBT Connector for maximum flexibility
