}Who does this wallet transact with? Recent activity (~100 transactions) aggregated into a ranked counterparty list: address, explorer name where known, interactions in/out, total native value, first/last seen, methods used. The related-wallets answer from open data — honest about being a recent-activity sample. Pay-per-call via x402 (USDC, Base).
| Argument | Type | Description |
|---|---|---|
| top | integer | Max counterparties to return (1-25, default 10) |
| address* | string | EVM address on Base (0x + 40 hex) |
| _payment | string | Optional base64 x402 PAYMENT-SIGNATURE payload. Omit to receive payment requirements. |

}THE general-purpose tool: use this whenever you need data or an action that no other tool here covers. Describe the task and we pick the single best x402 tool for it across the whole ecosystem (14,000+ tools) — including external sellers, paid from our treasury — run it, and return the result. Examples: "get the latest ethereum block height", "screen this wallet for sanctions", "search the web for X and extract the text", "latest SEC filings for AAPL", "price of ETH in USD". Give a plain-language "task" (we pick the tool) or an explicit "resource" URL, plus optional "body" input. Pay-per-call via x402 (USDC on Base): call without _payment to get the requirements, then retry with _payment set. Prefer this over hard-coding a specific seller.
