How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns the raw GraphQL query result from the target chain's subgraph, including matched on-chain entities such as pools, positions, swaps, tokens, or protocol metrics as structured JSON data fields.
Example use cases
Top liquidity pools by TVL
“Fetch the top 10 liquidity pools by total value locked on Base using the SperaxOS subgraph — run a GraphQL query for pool IDs, token pairs, and their TVL in USD.”
Wallet DeFi position lookup
“Query the SperaxOS subgraph on Base to get all open DeFi positions for wallet address 0xABC123... — I need the pool, deposited amounts, and current value.”
Recent token swap history
“Pull the last 50 token swap events from the SperaxOS subgraph on Base chain — give me the transaction hash, tokens swapped, amounts, and timestamps.”
Technical details
Endpoint
POSThttps://chat.sperax.io/api/x402/v1/erc8004/subgraph?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to run arbitrary GraphQL queries against DeFi subgraph data on a specific blockchain chain without managing API keys — ideal for agents that pay per-call with USDC and need flexible, schema-driven access to on-chain protocol data such as pools, swaps, positions, or token metrics.
Side effects
- Invalid or malformed GraphQL query syntax returns a GraphQL error response
- Unsupported or unknown chain identifier results in a 400 or empty response
- Query exceeds 10,000 character limit and is rejected
- Insufficient USDC payment or x402 payment failure blocks the request
- Variables object does not match query expectations causing a runtime GraphQL error
- Subgraph indexing lag may return stale data for very recent on-chain events
