Programmatic access to crypto's most trusted data

The Dune Data API provides programmatic access to Dune's blockchain analytics platform, allowing developers, analysts, and data teams to execute SQL queries, manage data, and retrieve results across multiple blockchains directly into their own applications, dashboards, or workflows.

The API gives you the same data that powers Dune dashboards: raw, decoded, and curated tables across 100+ blockchains, including Ethereum, Solana, Base, Arbitrum, Optimism, Polygon, and BNB Chain.

Both. Queries run over full historical data. Typical freshness is about 1 to 15 minutes for EVM chains, about 1 to 5 minutes for Solana, and about 1 hour for curated datasets.

Rate limits depend on your plan. On the Plus plan, write-heavy endpoints such as execute query allow 70 requests per minute, and read-heavy endpoints such as get execution result allow 200 requests per minute. On Enterprise plans, these limits start at 350 and 1,000 requests per minute. Free accounts are view-only, so API use needs a trial or a paid plan.

Yes. Dune MCP is Dune's official remote MCP server. Add https://api.dune.com/mcp/v1 to an MCP client such as Claude Code, Cursor, Codex, or OpenCode, and sign in with your Dune account. Your agent can then find tables, run SQL queries, and build charts and dashboards.

Any query you create on Dune can be converted into an API endpoint, making it possible to pull fresh, parameterized blockchain data into your products or internal systems without manual intervention.

You can access comprehensive, cross-chain data including protocol activity, wallet-level metrics, DeFi usage, NFT trends, and more, as well as combine your own datasets with Dune's indexed data.

Yes. Dune holds the full onchain Polymarket record as SQL tables, so you can query every Polymarket fill since November 2022 without paging an API or running your own indexer. Read Polymarket API vs Polymarket data on Dune: what you can query.

Yes, you can set up scheduled queries that run at regular intervals and trigger webhooks to send notifications when your query detects changes or meets specific conditions.

Programmatic analytics means you can automate query execution, data retrieval, and even data integration with other tools, enabling scalable and customizable analytics pipelines without manual dashboard use.

Dune provides client SDKs for Python, TypeScript, and Go, and you can also interact with the API using standard HTTP requests, making it compatible with most modern programming environments.

API usage is billed on a credit basis, with credits consumed for query executions and data retrieval, and efficiency improving with higher-tier plans.
