#oracle

Live cross-asset prices from Pyth, the largest decentralised first-party oracle, which aggregates prices contributed by exchanges, market makers and trading firms and serves them across 90+ blockchains. Pyth covers far more than crypto: around 3,000 feeds spanning crypto, US and global equities, FX pairs, commodities and precious metals. The feeds endpoint searches the feed registry by symbol or asset type; the price endpoint returns one feed's latest aggregate price with its confidence interval, exponent, EMA price and publish time; the prices endpoint returns many feeds at once. Each price carries a confidence band — Pyth's signature measure of how tightly publishers agree. Read live from Pyth, nothing stored. This is Pyth's own multi-asset first-party oracle layer — distinct from single-DEX oracles and single-asset-class price feeds.

Live oracle prices from GMX, the leading decentralised perpetual-swap exchange on Arbitrum and Avalanche. Unlike order-book DEXs, GMX executes trades against its GLP/GM liquidity pools at prices set by a keeper-signed oracle that quotes a MIN and a MAX price per token — the execution band traders open and close positions against. The prices endpoint returns every supported token's min/max/mid oracle price and the execution spread; the price endpoint returns a single token by symbol; the tokens endpoint returns the supported-token registry (contract address, decimals, synthetic flag); the spread endpoint ranks tokens by their oracle execution spread (the on-chain cost band of trading that token on GMX). Every endpoint accepts a chain parameter (arbitrum default, or avalanche). Read live from GMX's public oracle, nothing stored. This is GMX's own pool-DEX oracle min/max-price and execution-spread layer — distinct from centralised-exchange tickers, aggregate price feeds and order-book DEX feeds such as dYdX and Hyperliquid.
