Crypto technical indicators

Technical indicators for one perpetual computed deterministically from Hyperliquid candles: RSI(14), MACD(12,26,9) with signal and histogram, EMA 20/50/200, SMA 20/50, Bollinger(20,2) with bandwidth and %B, ATR(14) and window VWAP. Send POST /api/crypto-indicators with the required field coin and pay $0.002 per call over x402 or MPP (there is no free tier). It returns a JSON object with source, coin, interval, candles, window and 4 more.

Returns the latest close, the latest value of each, the last N series points (points, max 100), and a plain summary (trend vs EMA50, RSI zone, MACD cross on the latest bar). Set ohlcv to also get the last N OHLCV candles (open, high, low, close, volume) in the same call. interval 1m to 1M, limit = candles used (default 200, max 500). Choose a subset with indicators. No key, no LLM.

From an MCP client

catalog.call {
  "slug": "crypto-indicators",
  "params": {
    "coin": "BTC",
    "interval": "1h",
    "limit": 200,
    "points": 5
  }
}

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

Errors and behavior

• coin 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 GET or HEAD to /api/crypto-indicators returns the same 402 quote, so the price can be read without a body.
• 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/crypto-indicators", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "coin": "BTC",
    "interval": "1h",
    "limit": 200,
    "points": 5
  }),
});
