edgeandnode/gateway ↗What it does
Query blockchain data via The Graph Network
Best for
Decentralized apps (dapps) querying blockchain data without running a full node.
Inputs
- · GraphQL query
- · subgraph endpoint URL
- · optional: API key for rate-limited gateway
Outputs
- · blockchain entity data (transactions, contracts, token transfers)
- · JSON response
Requires
- · The Graph gateway (mainnet or testnet)
- · x402 payment network (Base or Base Sepolia)
Preconditions
Valid GraphQL query; subgraph deployed and indexed
Failure modes
- · Subgraph index lag (requires polling)
- · query timeout on large result sets
- · authentication required for production gateway
Trust signals
- · Mainnet and testnet environments
- · x402 payment integration
- · decentralized indexer architecture
