How this service works
Use when an agent needs base wallet profile. Returns Accountless Base mainnet wallet profile with native and ERC-20 balances, bounded transfer activity, counterparties, contracts, freshness metadata and evidence hash. $0.01.
Output
Returns a structured JSON object containing the wallet's native token balance, balances for any specified or detected ERC-20 tokens, a bounded list of transfer events within the requested lookback window, counterparty addresses encountered in those transfers, contracts interacted with, freshness metadata indicating data recency, and a cryptographic evidence hash for auditability.
Example use cases
Due diligence on a payment sender
“Before I accept this payment, can you pull the Base mainnet profile for 0xAbCd...1234 and tell me their recent transfer counterparties and token balances over the last 10000 blocks?”
Token portfolio snapshot for a Base address
“What ERC-20 tokens and ETH does the wallet 0xDead...Beef hold on Base right now? Include the USDC contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 as the asset filter.”
Audit trail for a suspicious wallet
“I need to investigate 0xFeed...Cafe on Base mainnet — give me its full wallet profile going back 100000 blocks, including all counterparties it has interacted with and an evidence hash I can reference later.”
Technical details
Endpoint
POSThttps://api.oblique.markets/api/v1/paid/base-wallet-profileWhen to prefer
Choose this endpoint when you need a comprehensive, single-call snapshot of a Base mainnet wallet — covering balances, transfer history, counterparties, and an auditable evidence hash — rather than making multiple separate calls for balances, transactions, and contract interactions. It is especially valuable for due diligence, fraud detection, wallet intelligence, or any workflow that needs a bounded, tamper-evident record of a wallet's activity.
Side effects
- Invalid or malformed wallet address returns a 400 error
- Unsupported chain value (not base/base-mainnet/eip155:8453) returns a validation error
- lookback_blocks set too large may hit internal limits and return a partial dataset or timeout
- Payment not settled triggers a 402 response requiring x402 micropayment
- ERC-20 contract address not deployed on Base returns empty token balance data
