Tools / Crypto & Base
Wallet Report $0.04 / call
Full Base wallet profile in one call.
GET /v1/base/wallet-report
Bundles four on-chain lookups into a single paid call: USDC balance, recent USDC transfers in and out, whether the address is an EOA or contract, and its x402 Bazaar merchant listings if it's a payTo. Built so an agent profiles a wallet without firing five separate requests.
Parameters
address required | 0x Base address to profile |
Example
macOS / Linuxcurl -s "https://quartermaster.surewhynot.app/v1/base/wallet-report?address=0x5253666c40432f009ebd99908b9cd2a7fd1019cb"
Windows (cmd or PowerShell)
curl.exe -s "https://quartermaster.surewhynot.app/v1/base/wallet-report?address=0x5253666c40432f009ebd99908b9cd2a7fd1019cb"
Unpaid, these return 402 Payment Required with the payment details in the header (add -i to see them). curl.exe ships with Windows 10+ and works in cmd and both PowerShell versions. To actually pay, use an x402 client (see Connect) or call it as the MCP tool. Cost: $0.04 per call.
FAQ
Why one call instead of the individual endpoints?
It runs the balance, transfers, address-type, and merchant lookups in parallel and returns one merged profile — fewer round-trips and one payment instead of four.
How do I pay for this endpoint?
Call it with no payment and you receive HTTP 402 with machine-readable payment requirements. Attach a USDC payment on Base with any x402 client (for example @x402/fetch) and retry — the whole loop is two requests. This call costs $0.04 in USDC.
Do I need an account or API key?
No. There are no accounts, logins, or API keys anywhere in Quartermaster. Payment is per call over the x402 protocol; your wallet is your identity.
Can I call this as an MCP tool instead?
Yes. Quartermaster is also an MCP server at /mcp, so any MCP client (Claude Code, Claude.ai, Cursor) can mount this tool. See /connect for setup.
