Capabilities

Tools 4

get_product

Full detail on one product by catalog id: price (USD + USDC atomic), category, description, bundle contents, cover, and — for buyable products — a live payment block fetched from the real x402 402 challenge (network, USDC contract, amount, pay-to wallet).

Discovered
how_to_buy

Get the precise, step-by-step x402 payment sequence to buy a product: live network/USDC-contract/amount/pay-to values from the real 402 challenge, assembled into ordered steps.

Discovered
list_categories

List categories present in the live catalog with product counts. Categories are heuristically derived from id/title (the catalog API has no category field of its own).

Discovered
search_products

Search Lawrence Lanoff's live digital-product catalog by keyword, price ceiling, and/or category. Returns id, title, price_usd, category, buyable_via_x402, x402_url (tagged ?src=mcp-remote for attribution — use this exact URL), and cover.
