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.

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will check 0xabf4…a9d0's payment record before paying it over the free read API. No key, no account.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
