- Onchain SQL (query Base withagent402.toolsRun 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.Livechecked Evidence 2/4x402x402 Bazaar4 payers
- Skill: Onchain analyst (SQLagent402.toolsAsk Base anything in one paid call: your SQL runs against indexed, DECODED chain data (events with parsed parameters, transactions, blocks, user-ops) with the live schema alongside - no indexer, no RPC archaeology. Onchain analyst (SQL over Base) skill pack: one x402 payment runs 3 underlying tools (onchain-sql-schema, onchain-sql, stats-summary); partial-success per step.Livechecked Evidence 2/4x402x402 Bazaar1 payer
- SQL execution certificate verifyagent402.toolsVerify an Ed25519 execution certificate against the exact SQL statement you are about to run - the gate your database layer calls before it obeys an agent. Checks the signature, the certificate version, the expiry, and that the statement's SHA-256 matches the one certified, so a certificate for a different (or edited) statement is rejected. Returns { valid, reason, payload } and never throws on a malformed token, so the executor always gets one uniform answer.Livechecked Evidence 2/4x402x402 Bazaar1 payer
- Function selector / event topicagent402.toolsResolve a 4-byte function selector or a 32-byte event topic hash to its known human-readable Solidity signatures, via the openchain.xyz signature database with 4byte.directory as fallback. Unknown selectors return {found:false} with an empty list, not an error.Livechecked Evidence 2/4x402x402 Bazaar2 payers
- Onchain SQL schemaagent402.toolsThe table + column schema for the onchain-sql tool - every queryable table (base.events, base.transactions, base.blocks, base.decoded_user_operations, base.transaction_attributions, solana.instructions, …) with its columns and types. Fetch once, then write SQL with confidence.Livechecked Evidence 2/4x402x402 Bazaar3 payers
- VIN decoder (NHTSA)agent402.toolsDecode a vehicle VIN via the US NHTSA vPIC database: make, model, year, trim, body class, engine, fuel type, plant and vehicle type. Accepts full or partial VINs. Use it when an agent holds a VIN and needs the vehicle's official specification - live government data, no key.Livechecked Evidence 1/4x402x402 Bazaar2 payers
- SQL statement guard with signedagent402.toolsReview a SQL statement before running it against production: a pass / warn / block verdict naming concrete risks (unbounded UPDATE or DELETE, tautological WHERE, DROP, TRUNCATE, statement stacking, privilege changes, catalog writes) and, on pass, an Ed25519 certificate bound to the statement's SHA-256 that a database layer can verify before executing. Use it as the last check between an agent and a destructive query.Livechecked Evidence 1/4x402x402 Bazaar1 payer
