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. Send GET /api/edgar-13f-datasets with no required fields (1 optional) and pay $0.003 per call over x402 or MPP (there is no free tier). It returns a JSON object with total, count, latest, dataSets, tables and 3 more.

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 hosted connector at https://agent402.tools/mcp needs a payment for edgar-13f-datasets; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• Every field is optional. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (Authorization: Bearer a402_...) also pays it.
• A POST with a JSON body to /api/edgar-13f-datasets is served as this GET, with the body as the input.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

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();
client.setSpendControls?.(false); // keep your own spending ceiling in code
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/edgar-13f-datasets?limit=3");
