DIA Decentralized Price Oracle API

healthy 3,919 Subscribers

Live decentralized price-oracle data from DIA, with no key. DIA aggregates trade data across many CEXes and DEXes into transparent on-chain price feeds. Get a symbol quotation (current price, yesterday's price, 24h change and volume); an asset quotation by blockchain and contract address — the same multi-chain oracle feed smart contracts consume; the catalogue of quoted assets with their chain, address and volume; and the list of supported symbols. Distinct from CEX tickers and CoinGecko-style aggregators: these are oracle reference prices across 949 symbols and 5,500+ assets.

Kujira On-Chain API

Live on-chain data for Kujira (the zero-inflation, fee-funded Cosmos DeFi L1, chain kaiyo-1) with no key: the on-chain price oracle (validator-fed USD exchange rates for dozens of assets), the Kujira chain staking economics (no inflation; fee-funded), the active validator set, the total KUJI supply, and the latest block.

Chainlink Price Feeds API

The on-chain prices that DeFi actually runs on, read live and keyless straight from Chainlink's price-feed contracts on Ethereum. Chainlink is the dominant oracle: a decentralised network writes each price on-chain and refreshes it on a heartbeat or when it moves past a deviation threshold, and thousands of lending, perpetual and stablecoin protocols read that exact number to value collateral and trigger liquidations. What matters is not just the price but whether the feed is fresh — a stale Chainlink feed is how DeFi protocols break — and that on-chain freshness is exactly what this exposes. The feeds endpoint lists every tracked Chainlink feed (crypto, stablecoins and FX) with its current on-chain answer, how many seconds ago it last updated and whether it is fresh. The feed endpoint returns one pair's full detail by name, including the round id, the update timestamp and the feed contract address. The health endpoint is the oracle-monitoring view: how many feeds are fresh versus stale, the stalest feed and the average update age — the on-chain reliability picture that a plain price API can't give you. Each price is read from the feed's latestRoundData and scaled by the feed's own on-chain decimals (USD feeds use 8); the update time is the contract's updatedAt. This is the Chainlink on-chain-oracle cut — distinct from the off-chain oracle-price APIs (which serve a price but not the on-chain feed's round and freshness) and from the exchange price feeds. Prices are in the feed's quote unit (USD here); times are UTC. No key, nothing stored beyond a short cache.

RedStone Oracle Prices API

Live oracle price feeds for over a thousand assets across every asset class in a single source — cryptocurrencies, US equities and ETFs, precious metals and commodities, fiat currencies and liquid-staking and real-world-asset tokens — served from the public RedStone oracle, no key, nothing stored. RedStone is the decentralized oracle that DeFi protocols read on-chain for their prices, so this is the cross-asset reference-price layer: the same feed gives you Bitcoin, Apple, gold, the euro and wstETH side by side, each stamped with the time the oracle signed it. The price endpoint returns one asset's latest oracle value. The prices endpoint returns many assets in one call — mix crypto, stocks, metals, FX and staking tokens freely. The symbols endpoint lists and searches every supported asset, from majors to obscure liquid-staking and tokenized real-world assets you will not find in a normal price feed. This is the multi-asset oracle-price cut — one feed for every class — distinct from the single-asset-class price, converter and precious-metals APIs in the catalogue.

Pyth Network API

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.
