Exchange tickers

Markets (tickers) listed on one exchange: base/target pair, last price, 24h volume, USD- and BTC-converted last price and volume, bid-ask spread %, trust score (green/yellow/red), anomaly and stale flags, trade URL and last trade time. Send GET /api/exchange-tickers with the required field exchange and pay $0.008 per call over x402 or MPP (there is no free tier). It returns a JSON object with source, fetchedAt, cached, exchange, exchangeName and 3 more.

Filter by `coins` (coin ids, max 10); pages of up to 100 tickers (`page`), trimmed to `limit` (default 50). Where is a coin actually trading, at what spread, and is the volume trusted. Cached in-process for 60 seconds.

Parameters

Example request

curl -i "https://agent402.tools/api/exchange-tickers?exchange=binance&coins=ethereum&limit=5"

Without payment this returns HTTP 402 Payment Required with the exact price for exchange-tickers; any x402 v2 or MPP client pays it and retries.

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

Errors and behavior

• exchange is required. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example, so the caller can correct it.
• 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 (Authorization: Bearer a402_...) also pays it.
• A POST with a JSON body to /api/exchange-tickers 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/exchange-tickers?exchange=binance&coins=ethereum&limit=5");
