How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON object with the wallet's recent ERC-20 token transfer events on the specified network (Base or Ethereum), including transaction details such as sender, recipient, amount, and block information for USDC or a specified contract, paginated via cursor.
Example use cases
Audit incoming USDC payments for a wallet
“Show me all USDC transfers into wallet 0xDef456... on the Base network over the last 2000 blocks — I need to verify a payment came through.”
Monitor Ethereum ERC-20 activity for a contract
“Fetch the recent token activity for wallet 0x789Ghi... on Ethereum for the USDT contract 0xdAC17F..., going back 1000 blocks.”
Paginate through historical wallet transactions
“I already queried wallet 0xJkl012... on Base and got a cursor back — can you continue from cursor position 50 and get the next batch of USDC transactions?”

Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/chain/wallet-activity?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain ERC-20 (especially USDC) transaction history for a specific wallet on Base or Ethereum, and want machine-payable per-call pricing without API key setup. Prefer it over block explorers when you need programmatic, agent-friendly access to wallet activity with cursor-based pagination and network selection.
Side effects
- Invalid wallet address format returns an error
- Unsupported network value (not 'base' or 'ethereum') causes validation failure
- lookback_blocks exceeding 5000 is rejected by schema validation
- No transactions found returns an empty result set
- RPC node unavailability may cause timeout or partial data
- Missing required 'address' field returns a 400-level error
