How this service works
API Gateway: The Graph decentralized indexing
Output
The agent receives the raw GraphQL JSON response from The Graph's decentralized indexing layer, including requested on-chain entities such as events, transactions, token balances, or protocol metrics depending on the subgraph queried.
Example use cases
Example prompt
“Query The Graph's decentralized indexing network for the latest Uniswap V3 swaps on Ethereum — send a GraphQL POST to the Uniswap V3 subgraph path and return the top 10 most recent swap events with token pairs and amounts.”
Technical details
Endpoint
POSThttps://httpay.xyz/api/gateway/thegraph/%7B*path%7D/*When to prefer
Use this endpoint when you need to query indexed blockchain data from The Graph protocol without managing your own API keys or subgraph hosting — ideal for AI agents that need structured on-chain data (DeFi, NFT, DAO) via GraphQL and want simple pay-per-call access with no subscription setup.
Side effects
- Invalid subgraph path returns 404 or upstream error
- Malformed GraphQL query body returns GraphQL error object
- Payment not included or insufficient USDC results in 402 Payment Required
- Subgraph not deployed or deprecated returns empty or error response
- Rate limiting or gateway timeout returns 503 or 504
