How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream Dune Analytics response body (JSON data, query results, analytics) passed through transparently after successful x402 micropayment verification, along with the content type header.
Example use cases
On-chain DeFi protocol TVL lookup
“Fetch the latest total value locked for Uniswap from Dune Analytics using path '/v1/query/998877/results' — pay the per-request fee from my wallet.”
NFT collection sales volume report
“Get me the last 7 days of NFT sales volume for Bored Apes from Dune Analytics at path '/v1/query/445566/results', paying the micropayment per call.”
Whale wallet activity monitoring
“Query Dune Analytics for the top 10 wallet addresses by ETH transfers in the last 24 hours using path '/v1/query/332211/results' and deduct the USDC fee automatically.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/dune?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic access to Dune Analytics blockchain/DeFi data and want to pay only per-query via x402 micropayments rather than maintaining a monthly Dune API subscription. Ideal for agents that query Dune infrequently or need cost-controlled on-chain data access with USDC micropayments baked into the request flow.
Side effects
- Insufficient USDC balance — payment fails and request is rejected with 402
- Invalid Dune Analytics path — upstream returns 404 or 400
- Dune API rate limit exceeded — upstream returns 429
- Malformed query parameters — upstream returns validation error
- x402 facilitator unavailable — payment cannot be processed
