# Blast API

[Blast API](https://blastapi.io/) is a decentralized platform that provides reliable and scalable node infrastructure
for accessing blockchain data. It supports multiple blockchain networks, offering seamless integration and
high-performance API endpoints for cross-chain decentralized applications (dApps).

## Enhanced Performance and Reliability

Blast API uses a decentralized network of third-party node providers, that ensure high availability and fast response
times. This architecture provides resilient infrastructure services crucial for dApps requiring real-time data access.

## Multi-Blockchain Support

Besides IOTA EVM, Blast API supports a wide range of blockchain networks, allowing access to multiple blockchains
through a single unified platform, therefore simplifying the development process and expanding the potential use cases
for dApps.

## Archival Nodes

Blast API includes archival nodes, which store all historical transaction data from the blockchain’s
genesis block to the present. This allows developers to query and retrieve past information, which is essential for
applications needing access to comprehensive blockchain histories.

You can find a full list of Blast API endpoints in the [Networks & Endpoints section](networks-endpoints.mdx).

# Subgraphs

:::info tl;dr;

Subgraphs provide a streamlined way for developers to access blockchain data relevant to their applications,
significantly enhancing developer efficiency and user experience.

:::

Subgraphs collect and organize blockchain data by application needs, making it readily accessible for developers. Unlike
blockchains that store data without application context, subgraphs allow you to quickly retrieve information pertinent
to your application and simplify real-time data access, facilitating the creation of
dynamic user interfaces and interactions in your applications.

## Subgraph Components and Operations

Subgraphs are built on [GraphQL](https://graphql.org/) APIs, enabling you to query on-chain transaction data
efficiently.
This feature is particularly useful for developers working with complex smart contracts requiring detailed frontend
interfaces. For instance, querying transactions within a specific liquidity pool becomes straightforward with subgraphs.
By defining a schema and indexing event data, you can utilize the generated GraphQL API for effective data querying.

### Subgraph Manifest

The manifest details the smart contracts your subgraph indexes, the events it tracks, and how event data is mapped to
queryable entities. This foundational document ensures your subgraph accurately reflects the blockchain data your
application needs.

### Subgraph Schema

The schema organizes your subgraph data, defining entities like pools in DeFi applications, and their attributes. It is
crucial for structuring your data to support efficient queries.

### Subgraph Mappings

Mappings process incoming blockchain events, specified in your [manifest](#subgraph-manifest), and store them
according to your [schema](#subgraph-schema).
These [AssemblyScript](https://www.assemblyscript.org/) codes are essential for translating raw blockchain data into a
format your application can easily query.

## Popular Use Cases for Subgraphs

Subgraphs have found widespread adoption in various blockchain applications, from DeFi to NFTs and DAOs, due to their
ability to index and query data effectively.

* **Custom Smart Contract Indexing**: Ideal for developers needing to index data for unique smart contracts, especially
those creating frontend interfaces.
* **Decentralized Finance (DeFi)**: Subgraphs provide real-time data on token prices, liquidity, and more, enhancing
DeFi
applications.
* **Non-fungible Tokens (NFTs)**: They allow for efficient querying of NFT ownership, transaction history, and off-chain
data.
* **Decentralized Autonomous Organizations (DAOs)**: Subgraphs facilitate on-chain decision-making and data analysis for
DAOs.
* **Gaming**: They support real-time data access, improving gameplay and in-game transactions.

## Benefits of Using Subgraphs

Subgraphs offer a developer-friendly approach to blockchain data indexing, compatible with various blockchains and
enhancing application security and resilience.

* **Ease of Use**: With familiar tools like AssemblyScript and GraphQL, subgraphs are accessible to developers,
simplifying
the backend data management.
* **Cross-Blockchain Compatibility**: They work across multiple EVM-compatible networks, allowing applications to
operate
seamlessly on different blockchains.
* **Security and Decentralization**: Opting for decentralized querying with subgraphs can reduce reliance on single data
sources, increasing application robustness.
