How this service works
Paid REST pass-through to `https://api.quicknode.com/sql/rest/v1/query`. Variable cost: the upstream response body's `credits` field is debited 1:1 from the caller's SIWX-authenticated drawdown balance (one SQL credit = one drawdown credit). Per-request `PAYMENT-SIGNATURE` is NOT accepted — callers must authenticate via SIWX and pre-fund credits.
Output
Returns a JSON object containing the query result rows and a 'credits' field indicating how many SQL credits were consumed (debited 1:1 from the caller's pre-funded drawdown balance).
Example use cases
Example prompt
“Run this SQL query against QuickNode's SQL API and return the results: SELECT block_number, transaction_hash, value FROM ethereum.transactions WHERE from_address = '0xABC123' ORDER BY block_number DESC LIMIT 10”
Technical details
Endpoint
POSThttps://x402.quicknode.com/sql/rest/v1/queryWhen to prefer
Choose this endpoint when you need to run structured SQL queries against QuickNode's blockchain data via a pay-as-you-go credit model authenticated with SIWX. Ideal for on-chain analytics, blockchain data extraction, and querying indexed blockchain datasets without managing your own infrastructure. Prefer this over raw RPC endpoints when you need relational/SQL-style access to blockchain data.
Side effects
- Insufficient drawdown balance — query rejected if SIWX-authenticated account lacks sufficient pre-funded SQL credits
- Authentication failure — missing or invalid SIWX credentials result in 401/403
- Malformed SQL query — syntax errors return a 400 with error details
- Query timeout — complex or expensive queries may time out
- Per-request PAYMENT-SIGNATURE not accepted — using wrong auth method results in rejection
- Rate limiting — excessive requests may be throttled
