How this service works
Use when an agent needs wallet transfers. Returns ERC-20 transfer history for one Base wallet, backed by the public Base transfer index: filter by token, direction and page, with normalized amounts, counterparties and timestamps; priced per bounded request $0.005/call via x402. $0.005.
Output
An array of ERC-20 transfer records for the specified Base wallet, each including normalized token amounts, counterparty wallet addresses, token contract details, and block timestamps; results are paginated via limit/offset and filtered by direction and token as requested.
Example use cases
Audit incoming payments to a wallet
“Show me all incoming token transfers to 0xAbC123... on Base — I need to verify which counterparties have sent funds and when, with normalized amounts.”
Track outgoing token transfers for accounting
“List the last 50 outgoing ERC-20 transfers from my Base wallet 0xDEF456..., filtered to USDC only, so I can reconcile my payments this month.”
Monitor all ERC-20 activity for a wallet
“Give me the full transfer history — both in and out — for Base wallet 0x789GHI... across all tokens, paginated 25 at a time starting from the beginning.”
Technical details
Endpoint
POSThttps://api.oblique.markets/api/v1/paid/wallet-transfersWhen to prefer
Choose this endpoint when you need structured, paginated ERC-20 transfer history for a specific Base wallet address with filtering by token contract and direction (in/out/all). Prefer it over a full wallet spy endpoint when you specifically want normalized historical transfer records rather than real-time surveillance or token balances. It is well-suited for accounting, auditing, and counterparty analysis workflows on the Base network.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain value (non-Base) is rejected by schema enum
- Offset beyond available records returns empty result set
- Payment failure via x402 blocks the request
- Token address filter with no matching transfers returns empty array
- Network timeout or Base RPC unavailability causes a service error
