The Graph

API

Decentralized GraphQL protocol for efficient blockchain data querying

Overview

The Graph is a decentralized indexing protocol enabling querying of blockchain networks (Ethereum, Polygon, Arbitrum, etc.) via GraphQL. Developers define subgraphs (custom schemas/data sources) to index specific events, transactions, or smart contract states. It provides GraphQL endpoints for accessing indexed data, with JSON-formatted responses. Use cases include building dApps needing real-time/historical blockchain data—like DeFi platforms tracking liquidity pools, NFT marketplaces showing ownership, or DAOs monitoring proposals—without syncing full nodes.

Example Integration (JavaScript)

script.js JS


fetch('https://thegraph.com')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));

Frequently Asked Questions

? Is The Graph free to use?

The hosted service offers free tiers for small projects; the decentralized network requires GRT tokens for query fees.

? Does it require an API Key?

Hosted service uses API keys for auth/rate limits; decentralized network uses wallet signatures instead of traditional keys.

? What is the response format?

Responses are in JSON, following GraphQL specification.
