API3 (API3) API and Price Oracle

The API3 price API returns real-time price data for API3, aggregated from individual trades across on-chain and off-chain sources. Developers integrate this endpoint into applications that require current API3 valuations, such as trading dashboards, portfolio trackers, lending protocols, or automated trading systems.

DIA provides the API3 price API by aggregating trade data from 100+ exchanges and constructing verifiable price feeds on its Ethereum layer-2 rollup, Lasernet. The free endpoint available on this page supports testing and evaluation. For production deployments or custom requirements—such as configurable data sources, pricing methodology, or update frequency—DIA builds dedicated feeds. Developers can request production-grade feeds through DIA's Discord or Telegram.

DIA publishes a free price API endpoint for API3 on this asset page, available for developers to test and evaluate at no cost. The free endpoint is designed for testing and evaluation purposes only, not for production deployments. Developers seeking production-grade or customized API3 price feeds can request dedicated feeds configured to their specific data sources, pricing methodology, and update frequency requirements. These custom feeds are built on request through DIA's Discord or Telegram channels.

A blockchain price oracle is an external data provider that supplies verified offchain information to smart contracts, enabling them to access real-world market prices and other data without leaving the blockchain.

DIA deploys price oracles for API3 across 60+ supported blockchains. These oracles deliver onchain API3 price data that smart contracts can consume directly. DIA aggregates trade data from 100+ exchanges to construct its price feeds, covering API3 alongside 3,000+ other assets.

DIA's oracle infrastructure runs on Lasernet, DIA's Ethereum layer-2 rollup, which makes each feed independently verifiable. A free API endpoint is available for testing. For production deployments or custom requirements, DIA builds dedicated feeds configurable by data sources, pricing methodology, and update frequency, requested via Discord or Telegram.

DIA's API3 price is built by aggregating individual trade data from on-chain and off-chain sources across multiple exchanges, rather than relying on a single exchange or liquidity pool. This approach draws from 100+ exchanges to construct a market-representative price for API3.

The sources included in the calculation and the pricing methodology applied to them are transparent. For production deployments, DIA builds dedicated price feeds where the data sources, aggregation method, and update frequency are all configurable according to specific requirements. Custom feeds can be requested via DIA's Discord or Telegram channels.

A free API endpoint is available on this asset's page for testing and evaluation purposes only and is not intended for production use.

API3 is a blockchain oracle infrastructure provider delivering price feeds across 60+ blockchains. Developers building on supported chains can integrate API3 price data into applications requiring verified market prices.

Lending protocols use API3 feeds to establish collateral values and liquidation thresholds, ensuring loans remain adequately backed as asset prices move. Decentralized exchanges and AMMs consume API3 data for price discovery, route optimization, and slippage protection during token swaps. Derivatives platforms rely on API3 feeds to settle perpetual futures, options, and other leveraged instruments with accurate, tamper-resistant pricing.

API3 aggregates trade data from 100+ exchanges covering 3,000+ assets. Developers can request dedicated feeds tailored to specific data sources, pricing methodology, and update frequency through DIA's Discord or Telegram for production deployments.

DIA aggregates trade data from 100+ exchanges to construct API3 price feeds with transparent sourcing that developers can inspect. Rather than accepting a fixed feed, teams can request a custom configuration specifying which data sources, pricing methodology, and update frequency best fit their application's requirements.

API3 trades across 60+ blockchains, and DIA deploys price oracles to any supported chain. Each feed remains independently verifiable because DIA's oracle infrastructure runs on Lasernet, DIA's Ethereum layer-2 rollup, allowing smart contracts to cryptographically validate pricing data.

Developers can begin by testing the free API endpoint available on this page for evaluation. For production deployments or custom configurations tailored to API3's specific use case, teams request a dedicated feed through DIA's Discord or Telegram channels.
