Pyth price (latest)

$0.001 per call · USDC via x402 · POST /api/price-pyth

Latest aggregated price for one or more Pyth feeds, sourced live from Pyth's Hermes service. Use when you need an ORACLE-grade price with a published confidence interval (cross-checking an exchange feed, settling onchain logic); for a plain fiat quote crypto-price is simpler and cheaper. Identify feeds by hex feed-id (preferred - full precision) or by a small set of well-known aliases (BTCUSD, ETHUSD, SOLUSD, USDC, USDT). Each feed returns price, confidence interval, and publish-time so an agent can decide whether the quote is fresh enough to act on.

Input

FieldTypeDescription
ids *arrayPyth feed IDs (hex, with or without 0x) or known aliases (BTCUSD, ETHUSD, SOLUSD, USDC, USDT). 1-20 entries.

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/price-pyth", {
