Onchain SQL schema

The 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.

Input

No parameters.

Example output

{
  "schema": {
    "base.events": [
      {
        "name": "block_number",
        "type": "UInt64"
      }
    ]
  }
}

Try it — see the 402 challenge (free)

curl -i "https://agent402.tools/api/onchain-sql-schema"

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/onchain-sql-schema");
