How this service works
Deterministic-first data for agents, paid per call in USDC over x402 v2: DeFi yields, Base token and wallet cards, Polymarket odds and backtests, news, fact checks, cited briefs. 20 routes, $0.005-$1
Output
A JSON object containing: wallet kind (EOA or contract), ETH balance, list of token holdings with symbol/balance/decimals, total transaction count, token transfer count, first-seen timestamp, last-activity timestamp, any flags, a human-readable summary sentence, and attribution to Blockscout/Base RPC data sources.
Example use cases
Due diligence on a counterparty wallet
“Before I send funds, can you check the Base address 0x1234567890abcdef1234567890abcdef12345678 — how old is it, how many transactions has it made, and what tokens does it hold?”
Portfolio snapshot for a tracked address
“Give me a quick on-chain summary of 0xabcdef1234567890abcdef1234567890abcdef12 on Base — ETH balance, any token holdings, and the last time it was active.”
Identify wallet type before interacting
“Is 0x46f64bec31eaf281176f9bb5899107a80e932b45 a regular wallet or a smart contract on Base, and what's its current ETH balance?”
Technical details
Endpoint
POSThttps://aiworker.duckdns.org/v1/check/walletWhen to prefer
Use this endpoint when you need deterministic, sourced on-chain facts about a specific Base network address — balances, activity history, and token holdings — rather than price feeds or identity/label lookups. It is paid per-call via USDC/x402, making it suitable for agent workflows that need verifiable blockchain data without running a full node or managing RPC infrastructure.
Side effects
- Invalid address format (not 0x + 40 hex chars) returns a validation error
- Address not found on Base returns empty or null holdings
- Blockscout API downtime may cause upstream fetch failure
- Smart contract addresses return kind='contract' but may have limited EOA-specific fields
- Very new addresses with no transactions may return minimal data
