Harmony (ONE) API and Price Oracle

The Harmony price API is a data endpoint that returns real-time price information for ONE, Harmony's native token. It aggregates individual trade data from on-chain and off-chain sources across multiple exchanges to deliver current market prices for ONE token holders and developers.

Developers integrate this API into applications requiring live ONE price feeds: trading dashboards, portfolio trackers, DeFi protocols, and price-monitoring tools all rely on it. The API supplies structured price data that applications query at intervals or upon specific events.

DIA provides a Harmony price API with a free endpoint on this page for testing and evaluation. For production deployments, DIA builds custom, production-grade Harmony feeds. These are configurable by data sources, pricing methodology, and update frequency, requested through DIA's Discord or Telegram channels.

DIA publishes a free Harmony price API endpoint on this asset page that developers can access for testing and evaluation at no cost. The free endpoint is designed for non-production use and lets developers assess how Harmony price data integrates with their applications.

For production deployments or customized Harmony feeds, DIA builds dedicated price oracles tailored to specific requirements around data sources, pricing methodology, and update frequency. Production feeds can be requested through DIA's Discord or Telegram channels, where the team works with developers to configure the oracle for their needs.

A blockchain price oracle is an external data provider that supplies verified information from off-chain sources to smart contracts on a blockchain. Price oracles enable smart contracts to access real-world market data they cannot retrieve independently.

DIA can deploy a Harmony price oracle on any supported chain to deliver verified ONE token price data directly to smart contracts. DIA's oracle infrastructure runs on Lasernet, DIA's Ethereum layer-2 rollup, which makes each price feed independently verifiable on-chain. This architecture ensures that ONE price data remains trustworthy and tamper-resistant.

For production deployments or custom requirements, DIA builds dedicated price feeds configurable by data sources, pricing methodology, and update frequency. Developers can request a custom Harmony price oracle via DIA's Discord or Telegram channels.

DIA's Harmony price is calculated by aggregating individual trade data for ONE across multiple on-chain and off-chain sources spanning many exchanges. Rather than relying on a single exchange or liquidity pool, the aggregation draws from numerous venues to construct a market-representative price.

The sources feeding into this calculation and the pricing methodology applied to them are transparent and publicly documented. For production deployments, DIA builds dedicated price feeds where both data sources and calculation methodology can be configured to meet specific requirements. This configurability allows applications to tailor feeds to their particular risk tolerance, liquidity preferences, and operational needs.

Developers seeking custom Harmony price feeds can request configuration details through DIA's Discord or Telegram channels.

Harmony (ONE) is a layer-1 blockchain focused on fast, low-cost transactions. Developers building on Harmony can use ONE price feeds to power several application types.

Lending and collateral protocols require real-time ONE pricing to calculate loan-to-value ratios and trigger liquidations when collateral value falls below safety thresholds. Cross-chain bridge contracts rely on accurate ONE pricing to determine conversion rates and manage wrapped asset redemptions between Harmony and other chains. Decentralized exchanges and automated market makers use ONE price feeds to prevent flash-loan attacks and execute fair-value swaps between ONE and other tokens in liquidity pools.

DIA's price oracle delivers these feeds by aggregating trade data across 100+ exchanges, making each feed independently verifiable on Harmony's network.

DIA aggregates Harmony price data from 100+ exchanges across on-chain and off-chain sources, making sourcing transparent and auditable. Developers can inspect which venues and trade pairs feed each price point, reducing reliance on opaque oracle operators.

For production use, DIA builds custom Harmony feeds configured by the developer: choice of data sources, pricing methodology, and update frequency. This flexibility suits different risk profiles and use cases, from stablecoin collateral monitoring to derivative pricing.

DIA deploys across 60+ blockchains including Harmony, simplifying multi-chain applications. Each feed runs on Lasernet, DIA's Ethereum layer-2 rollup, enabling independent verification of price calculations directly on-chain.
