Onchain SQL (query Base with

agent402.tools · x402

Run read-only SQL against indexed, DECODED blockchain data - base.events (decoded logs with parameters), base.transactions, base.blocks, base.decoded_user_operations, base.transaction_attributions (builder codes), plus solana.instructions (filter it by block_time). ClickHouse-dialect SELECTs, server-side grammar validation, up to 1,000 rows per call (a larger result is cut at 1,000 and says so). Ask Base anything - token flows, event analytics, gas studies - in one call, no indexer to run.

x402: an unpaid request gets a 402 with the price and pay-to wallet. The check never pays.

Payments

wallets paid it, last 30 days: 2
independent of the seller: 2
paid in two or more weeks: 0
USDC payments: 4

Counted by addrbook from USDC transfers to the wallets it asks to be paid at, on Arc. A payer is independent when it is not one of the seller's own wallets and the seller did not fund it; the largest payer made 75% of the payments. Naming a wallet does not prove it is this seller's, unless a signature shows that above. Counted 10 Nov 2026, 06:29 UTC. How payers are counted
