USD Coin (USDC) API and Price Oracle

The USD Coin price API returns real-time USDC price data sourced from aggregated trades across on-chain and off-chain exchanges. Developers integrate this endpoint into applications that need current USD Coin valuations for trading interfaces, portfolio dashboards, settlement logic, or risk management systems. The API delivers a single, verified price point rather than requiring applications to query multiple sources independently.

DIA offers a USD Coin price API that aggregates individual trade data from 100+ exchanges covering 3,000+ assets. The free price-feed endpoint available on this page is available for testing and evaluation purposes only. For production deployments or custom requirements, DIA builds dedicated, configurable feeds where data sources, pricing methodology, and update frequency are tailored to application needs. Requests are handled through DIA's Discord or Telegram channels.

DIA publishes a free USD Coin price API endpoint on this asset page, available to developers for testing and evaluation at no cost. The free endpoint allows developers to examine DIA's price aggregation methodology and data quality before committing to a production deployment.

The free endpoint is designed for evaluation only and is not intended for production use. Developers requiring a production-ready USD Coin price feed, or those needing customization around data sources, pricing methodology, or update frequency, should submit a request via DIA's Discord or Telegram. DIA builds dedicated feeds tailored to specific production requirements.

A blockchain price oracle is an external data provider that supplies verified offchain information to smart contracts, allowing decentralized applications to access real-world market prices and other data without relying on a single centralized source.

DIA can deploy a USD Coin price oracle on any of its 60+ supported blockchains, delivering onchain USDC price data that smart contracts can consume. DIA's price feeds aggregate individual trade data from 100+ exchanges across both onchain and offchain sources, covering 3,000+ assets including USDC.

DIA's price oracle infrastructure runs on Lasernet, DIA's Ethereum layer-2 rollup, which enables each feed to be independently verifiable. Custom price oracles are configurable by data sources, pricing methodology, and update frequency, requested through DIA's Discord or Telegram channels for production deployments.

DIA's USDC price is calculated 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 numerous trading venues to construct the feed. The sources and pricing methodology are transparent and documented.

For production deployments, DIA builds dedicated price feeds for USDC that are configurable by data sources, pricing methodology, and update frequency. Custom feed parameters can be requested through DIA's Discord or Telegram channels. The underlying infrastructure runs on Lasernet, DIA's Ethereum layer-2 rollup, which enables independent verification of each feed by market participants.

USDC is a stablecoin pegged to the US dollar, so its price feed serves specific use cases where price certainty and fiat conversion matter. Developers commonly integrate USDC price data into lending protocols to calculate collateral values and loan-to-value ratios when USDC is accepted as collateral alongside volatile assets. Stablecoin-to-stablecoin swap interfaces use USDC pricing to execute arbitrage between USDC and other dollar-pegged tokens, capturing small discrepancies when they drift from parity. On-chain settlement systems also consume USDC price feeds to determine conversion rates when processing cross-chain payments or converting between stablecoins and native assets for final settlement. A price oracle ensures these calculations reflect actual market conditions rather than relying on stale or manipulated data.

DIA aggregates USD Coin price data from 100+ exchanges, combining on-chain and off-chain sources to construct a transparent feed. Developers can inspect which sources and trades contribute to each price point, rather than relying on opaque methodology.

DIA deploys price oracles across 60+ blockchains, so teams building on any supported chain can integrate USD Coin feeds without vendor lock-in. Each feed runs independently verifiable on Lasernet, DIA's Ethereum layer-2 rollup, enabling smart contracts to audit data provenance directly.

Custom feeds let developers configure data sources, pricing logic, and update frequency to match application requirements. A free test endpoint on this page supports evaluation. For production use or specific parameters, teams request a dedicated feed via DIA's Discord or Telegram channels.
