About this API

Dune Analytics is an on-chain analytics platform founded 2018, positioned as "SQL on blockchain". Background: on-chain data is public but hard to query directly with SQL (raw data is binary event logs). Dune team indexes all major chains' data into relational tables (ethereum.transactions, uniswap_v3.swaps, etc.); analysts write standard SQL for complex queries. Dune's website has 1M+ community-shared queries and dashboards — all popular DeFi protocols (Uniswap, Aave, Curve) have official dashboards showing DAU, TVL, revenue, and core metrics. Dune API programmatizes these queries — e.g. daily auto-trigger to fetch latest TVL data to your own dashboard.

Strengths & limitations

Strengths

Familiar SQL instead of GraphQL for on-chain data
Pre-indexed data (no ETL required)
Rich existing dashboard templates (Dune community has 1M+ public queries)

Limitations

Query latency (complex queries: seconds to minutes)
Free tier credits insufficient for commercial
Mainly for analysts, not suitable for real-time trading

Example request

Generic template — replace <endpoint> with the real path from the docs.

curl https://dune.com/<endpoint> \
  -H "Authorization: Bearer $API_KEY"
# Some providers use X-Api-Key instead — verify in the docs.

Getting started

Sign up at dune.com for an API key. Write SQL on the website to get a query ID, POST /v1/query/{queryId}/execute to run, GET /v1/execution/{executionId}/results for results.

FAQ

How real-time is it?+

Not real-time — indexed data typically has 5-10 min delay. For real-time, use RPC nodes or Subgraph.

How are credits calculated?+

By compute resources consumed. Simple queries: 1-10 credits. Complex multi-year aggregations: hundreds of credits.
