How this service works
On-chain x402 settlement summary for an address from the decentralized x402 Base subgraph on The Graph Network. POST {address}. Returns lifetime stats as payer + recipient (totalPayments, totalVolume, first/last seen), recent 10 payments each direction, facilitator metadata if applicable, plus indexed_through_block for freshness. Decentralized, verifiable. Distinct from /ask. $0.01 USDC on Base.
Output
Returns a structured JSON object with lifetime stats (totalPayments, totalVolume, firstSeen, lastSeen) for the address as both payer and recipient, the 10 most recent payments in each direction, facilitator metadata if the address is a facilitator, and an indexed_through_block field indicating data freshness. Data is sourced from the decentralized x402 Base subgraph on The Graph Network and is verifiable on-chain.
Example use cases
Example prompt
“Pull the full x402 settlement summary for wallet address 0xAbc123... on Base — I want to see lifetime stats as both payer and recipient, the last 10 payments in each direction, and any facilitator info.”
Technical details
Endpoint
POSThttps://graphadvocate.com/onchain-x402/addressWhen to prefer
Use this endpoint when you need verifiable, decentralized on-chain x402 settlement data for a specific wallet address, including both payer and recipient history, without relying on a centralized database. Prefer this over /ask when you need structured JSON stats rather than natural-language answers, or when you need machine-readable data for downstream agent processing.
Side effects
- Address not found or has no x402 activity — returns empty stats or zero counts
- Invalid or malformed address — returns 400 or error response
- Subgraph indexing lag — indexed_through_block may be behind latest block
- Network or subgraph unavailability — service timeout or 5xx error
- Payment failure for $0.01 USDC — request not processed if payment not settled
