The Graph
Provides a decentralized indexing and query layer for blockchain data, allowing agents to run structured GraphQL queries against pre-indexed subgraphs covering DeFi protocols, NFT markets, DAOs, and other on-chain data — without running a full node.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API keys for the hosted service should be treated as secrets and not embedded in client-side code. Decentralized network queries involve on-chain GRT transactions — private key management is the agent's responsibility and a significant security surface.
⚡ Reliability
Best When
An agent needs structured, queryable access to historical or current on-chain DeFi/NFT/DAO data without managing RPC node infrastructure or parsing raw event logs.
Avoid When
You need sub-second latency for live trading signals, mempool data, or data from blockchain networks where no community subgraph exists.
Use Cases
- • Query historical Uniswap swap events, liquidity pool states, and token prices from a specific block range without running an Ethereum archive node
- • Retrieve a wallet's full transaction history across a DeFi protocol (Aave, Compound, Curve) using protocol-specific subgraphs
- • Aggregate NFT collection sales volume, floor price history, and holder distribution from marketplace subgraphs
- • Monitor DAO governance proposals, votes, and treasury movements by querying governance subgraphs in real time
- • Build cross-protocol analytics by querying multiple subgraphs in parallel and joining results on shared wallet addresses
Not For
- • Academic or scientific literature — this is exclusively blockchain/on-chain data infrastructure with no relevance to scholarly research
- • Real-time mempool or unconfirmed transaction data — subgraphs index confirmed blocks only, with a small indexing lag
- • Chains without deployed subgraphs — coverage depends on community-deployed indexers; obscure chains may have no suitable subgraph
Interface
Authentication
Hosted service (Subgraph Studio) requires an API key passed as a query parameter or header. Decentralized network queries require GRT token staking and payment to indexers. Development/test queries on the hosted service are free up to limits.
Pricing
Hosted service: free tier then pay-per-query in USD. Decentralized network: queries are paid in GRT (Graph Token) to indexers — requires acquiring and staking GRT. Pricing on the decentralized network varies by indexer and query complexity. Enterprise plans available with SLAs.
Agent Metadata
Known Gotchas
- ⚠ GraphQL errors are embedded in a 200 OK response body — agents must check response.errors, not just HTTP status, to detect failures
- ⚠ Each subgraph has its own schema; agents must fetch and parse the subgraph schema before constructing queries, as there is no universal schema
- ⚠ Subgraphs can fall behind chain head (indexing lag) — the '_meta { block { number } }' field should be queried to verify data freshness before trusting results
- ⚠ The default result limit is 100 records; agents must implement skip/first pagination and check for truncation or they will silently miss data
- ⚠ Subgraphs deployed to the decentralized network may be deprecated or have no active indexers — queries fail silently or return stale data if no indexer is serving the subgraph
