How this service works
Bundled execution of the Onchain analyst (SQL over Base) workflow - Ask Base anything in one paid call: your SQL runs against Coinbase's indexed, DECODED chain data (events with parsed parameters, transactions, blocks, user-ops) with the live schema alongside - no indexer, no RPC archaeology. One x402 payment runs 3 underlying tools (onchain-sql-schema, onchain-sql, stats-summary); partial-success per step.
Output
Returns the rows resulting from the SQL query executed against Coinbase's indexed, decoded Base blockchain data — including decoded event parameters, transaction fields, block metadata, and user-op details, formatted as a structured result set
Example use cases
Example prompt
“Run this SQL against Base chain data and show me the results: SELECT contract_address, COUNT(*) as event_count FROM decoded_events WHERE block_time > now() - INTERVAL 1 DAY GROUP BY contract_address ORDER BY event_count DESC LIMIT 20”
Technical details
Endpoint
POSThttps://agent402.tools/api/skill/onchain-analystWhen to prefer
Use this endpoint when you need to run arbitrary analytical SQL queries against decoded Base blockchain data — especially when you need access to parsed event parameters, decoded transaction fields, or aggregated onchain metrics. Prefer over raw RPC calls when you want SQL-level filtering, joining, and aggregation over indexed chain data without running your own indexer. Best for analytics, dashboards, and investigative onchain queries on Base L2.
Side effects
- Non-SELECT SQL rejected (INSERT/UPDATE/DELETE not allowed)
- Query exceeds time bound or row limit
- ClickHouse-dialect incompatibility with submitted SQL
- Invalid table or column reference (schema mismatch)
- Payment failure or insufficient USDC balance (x402 payment required)
- Rate limiting or timeout on large aggregations
