Technical details
Endpoint
POSThttps://httpay.xyz/api/gateway/thegraph/%7B*path%7DWhen to prefer
Choose this endpoint when you need to query The Graph's decentralized indexing network without managing your own API key or subscription, especially for one-off or low-frequency subgraph queries where pay-per-call micropayments are more convenient than a billing plan. Ideal for AI agents that need to fetch indexed blockchain data (DeFi, NFTs, DAOs) on demand.
Side effects
- Payment not included or insufficient USDC causes 402 Payment Required
- Invalid or non-existent subgraph path returns 404
- Malformed GraphQL query returns 400 Bad Request
- Subgraph not yet synced returns stale or empty data
- The Graph network congestion causes timeout or slow response
- Path wildcard not correctly encoded causes routing failure
