B3 (B3) API and Price Oracle

The B3 price API is a data service that returns real-time price information for B3, aggregated from trades across multiple exchanges and blockchain sources. Developers integrate a B3 price API into applications to display current market rates, execute trading logic, calculate portfolio values, or trigger smart contract functions based on live B3 market data.

DIA offers a B3 price API that aggregates individual trade data across on-chain and off-chain sources to deliver verifiable price feeds. The free API endpoint available on this page is suitable for testing and evaluation. For production deployments or custom requirements, DIA builds dedicated B3 feeds configurable by data sources, pricing methodology, and update frequency. Developers can request a production-grade feed through DIA's Discord or Telegram.

DIA publishes a free B3 price API endpoint on this asset page, available for developers to test and evaluate without cost. The free endpoint delivers market price data for B3, the Brazilian stock exchange's digital asset, sourced from DIA's aggregation of on-chain and off-chain trading data.

The free endpoint is intended for testing and evaluation only, not production use. Developers requiring production deployment or customised B3 feeds configurable by data sources, pricing methodology, and update frequency can request a dedicated feed via DIA's Discord or Telegram channels.

A blockchain price oracle is an external data provider that supplies verified price information from off-chain sources to smart contracts on a blockchain. Smart contracts cannot directly access real-world data, so they rely on oracles to fetch and deliver trustworthy pricing information.

DIA can deploy a B3 price oracle on any of its 60+ supported blockchains, delivering verified on-chain B3 price data that smart contracts can consume. DIA's oracle infrastructure runs on Lasernet, DIA's Ethereum layer-2 rollup, which makes each price feed independently verifiable. A free API endpoint is available for testing and evaluation.

For production use or custom configurations—such as selecting specific data sources, pricing methodology, or update frequency—developers can request a dedicated B3 price oracle through DIA's Discord or Telegram channels.

DIA's B3 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 a broad set of market participants and trading venues to form the price input.

The data sources and pricing methodology used to construct the B3 feed are transparent. For production deployments, the data sources, pricing logic, and update frequency are configurable based on specific application requirements. Custom feeds can be requested through DIA's Discord or Telegram channels.

A free testing endpoint is available on this page for evaluation purposes, though production implementations use dedicated feeds tailored to individual needs.

B3 is a utility token on the Arbitrum blockchain used within the B3 ecosystem for governance and protocol participation. Developers can integrate B3 price feeds to build several application types.

Governance and staking dashboards rely on accurate B3 pricing to display token holder positions and voting power in real time. Decentralized exchanges and automated market makers require reliable price data to execute swaps and maintain liquidity pools containing B3. Treasury management tools use B3 price feeds to track protocol reserves and calculate the value of community funds held in B3 tokens.

DIA's price oracle delivers aggregated B3 data across multiple sources, making these applications independently verifiable and suitable for production deployment across supported blockchains.

DIA delivers transparent, configurable price feeds for B3, a governance token on Ethereum. Developers can inspect exactly which exchanges and trade data sources feed into each price point, rather than relying on opaque aggregation.

DIA builds custom feeds tailored to specific needs: source selection, pricing methodology, and update frequency all configurable. This flexibility matters for B3 liquidity patterns across venues. The infrastructure deploys across 60+ blockchains, so a B3 feed can reach any supported chain.

Each feed is independently verifiable through Lasernet, DIA's Ethereum layer-2 rollup, enabling on-chain confirmation of data integrity. Developers can begin by testing the free API endpoint on this page, then request production feeds through DIA's Discord or Telegram for custom requirements.
