Cardstack (CARD) API and Price Oracle

The Cardstack price API is a data endpoint that returns real-time CARD token pricing derived from aggregated trade data across on-chain and off-chain sources. Developers integrate this API into applications to fetch current CARD prices, historical price points, or trigger logic based on price movements without building their own data aggregation infrastructure.

DIA offers a Cardstack price API that pulls from 100+ exchanges covering thousands of assets. The free endpoint available on this page supports testing and evaluation. For production deployments, DIA builds dedicated Cardstack feeds configurable by data sources, pricing methodology, and update frequency. Developers requiring custom specifications can request these feeds through DIA's Discord or Telegram channels to ensure feeds meet specific application requirements and scale needs.

DIA publishes a free Cardstack price API endpoint on this asset page, available for developers to test and evaluate at no cost. The free endpoint is intended for testing and evaluation purposes only, not for production use.

For production deployments or customized Cardstack price feeds, DIA builds dedicated feeds configured to specific data sources, pricing methodology, and update frequency requirements. Developers can request production or custom feeds 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 onchain applications to access real-world market prices and other data they cannot retrieve directly.

DIA can deploy a Cardstack price oracle on any supported blockchain, delivering verified CARD price data for smart contracts to consume. Cardstack is a framework for building decentralized applications; its native token CARD is traded across multiple exchanges and represents value within that ecosystem. DIA's price oracle infrastructure runs on Lasernet, DIA's Ethereum layer-2 rollup, which makes each feed independently verifiable onchain.

For production deployments or custom requirements, DIA builds dedicated price feeds configurable by data sources, pricing methodology, and update frequency. Requests can be made via DIA's Discord or Telegram.

DIA calculates the Cardstack price by aggregating individual trade data for CARD from on-chain and off-chain sources across multiple exchanges. Rather than relying on a single exchange price or reading from one on-chain liquidity pool, DIA's methodology combines trades from many venues to produce a market-wide price estimate. The sources and pricing methodology used in this calculation are transparent and publicly documented. For production deployments, DIA can configure dedicated Cardstack price feeds with custom data sources, weighting schemes, and update frequencies tailored to specific application requirements. These custom configurations are available through DIA's Discord or Telegram channels.

Cardstack (CARD) is a utility token for the Cardstack framework, a platform designed for building decentralized applications with card-based interfaces and data organization. Developers consuming Card price data from a blockchain price oracle can build several concrete applications.

Collateralized lending protocols can accept CARD as collateral, requiring continuous price feeds to calculate loan-to-value ratios and trigger liquidations. Decentralized exchanges and automated market makers listing CARD pairs need real-time pricing to execute swaps and manage liquidity pools accurately. Staking and reward distribution systems within Cardstack applications use CARD price data to denominate or calculate yields in fiat equivalents.

DIA aggregates CARD trade data across multiple exchanges to deliver verifiable price feeds deployable on any supported blockchain.

Developers building with Cardstack can source price data through DIA's price oracle infrastructure, which aggregates individual trade data from 100+ exchanges to cover 3,000+ assets. DIA's feeds are transparent and configurable: the data sources, pricing methodology, and update frequency can all be tailored to specific application requirements rather than accepting a fixed feed design.

Cardstack price feeds deploy across 60+ blockchains, enabling consistent data access regardless of target chain. Each feed is independently verifiable through Lasernet, DIA's Ethereum layer-2 rollup, removing reliance on oracle provider assertions alone.

Developers can evaluate DIA's Cardstack pricing using the free test endpoint available on this page. For production use or custom feed specifications, DIA accepts requests via Discord or Telegram.
