How this service works
Blockchain data APIs with x402 payments on Solana + Base via PayAI facilitator. 7 endpoints covering bridge routing, whale alerts, DeFi yields, RPC, NFT, token, and transaction history.
Output
Returns a list of on-chain transactions matching the specified filters, including sender and receiver addresses, amounts, timestamps, and transaction hashes for the requested chain and address criteria.
Example use cases
Audit DeFi wallet activity
“Get me the last 200 transactions for the wallet 0x1234...abcd on Arbitrum, sorted from newest to oldest, so I can review its recent DeFi activity.”
Monitor incoming transfers to a contract
“Fetch all incoming transactions to contract 0xDeAd...BeeF on Polygon — up to 500 results — sorted oldest first.”
Trace sender activity on Base
“Show me the most recent 25 transactions sent from address 0xAaaa...1111 on Base, sorted descending by time.”

Endpoint
POSThttps://solana-x402-xi.vercel.app/api/v1/tx-historyWhen to prefer
Choose this endpoint when you need on-chain transaction history for EVM-compatible chains (Ethereum, Base, Polygon, Arbitrum) with flexible filtering by sender, receiver, sort order, and count. It is particularly useful when you want micropayment-gated access ($0.01 USDC per call via x402) without a subscription, and when you need fast, per-request lookup of wallet or contract activity rather than streaming or webhook-based monitoring.
Side effects
- Missing required 'chain' query parameter returns a validation error
- Invalid or unsupported chain name results in an error response
- Payment failure or insufficient USDC balance causes x402 payment rejection
- Malformed wallet address yields no results or an error
- maxCount outside the 1-1000 range may be rejected or clamped
- Rate limiting or network congestion may cause timeouts
