EDGAR Form 13F data sets (index)

The SEC's bulk Form 13F Data Sets: every quarterly (2013Q2-2023Q4) and rolling three-month (2024-) archive the SEC publishes, newest first, with its window, size and download URL, plus the seven tables each archive carries (SUBMISSION, COVERPAGE, OTHERMANAGER, OTHERMANAGER2, SIGNATURE, SUMMARYPAGE, INFOTABLE) and the readme. Read from sec.gov's own listing, cached 6 hours. Pair with edgar-13f-dataset-head to read a bounded head of one table without downloading the archive.

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";
import { metaTitle, metaDescription } from "./seo-meta.js";

const client = new x402Client();
client.setSpendControls?.(false); // @x402/core 2.23+ refuses anything over $1 or off the pegged-asset list by default; keep your own ceiling in code instead
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);
