Tokenized asset markets

Market data for tokenized real-world assets - tokenized stocks (Nvidia, Tesla, pre-IPO names), ETFs and commodities like gold - ranked by market cap or volume: price, market cap, 24h volume, 24h high/low and change, in your currency. Send GET /api/rwa-markets with no required fields (6 optional) and pay $0.006 per call over x402 or MPP (there is no free tier). It returns a JSON object with source, fetchedAt, cached, currency, type and 5 more.

Filter by type or a list of ids. Note these are the ONCHAIN wrappers' figures (what is tokenized and trading), not the underlying's exchange listing. Cached in-process for 60 seconds.

Example request

curl -i "https://agent402.tools/api/rwa-markets?type=stock&order=market_cap_desc&perPage=10"

  }

The hosted connector at https://agent402.tools/mcp needs a payment for rwa-markets; 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/rwa-markets 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/rwa-markets?type=stock&order=market_cap_desc&perPage=10");
