Agent-payable · x402 · Base USDC
A model cannot scrape Alibaba tiers reliably, pick an HS code, apply MFN + Section 301, and add sea freight into a per-unit landed cost — then hand you evidence URLs. That is the gap we sell: public-web procurement research and trade math, paid in USDC.
Not “AI can’t shop.” Specific jobs that fail without browsers, customs tables, and receipts.
Finding FOB tiers for “22 momme silk pillowcase × 500 → US” means reading live listing pages, MOQ fields, and lead-time tables — not inventing a price from training data. We research public pages only; we never email suppliers or place orders.
FOB is not what you pay at the dock. Agents need MFN + Section 301 style duty, sea/air proxies, and fees rolled into per-unit landed cost — with every assumption labeled when inferred.
Unpaid routes return 402. Settlements are Base USDC via x402.
Identity is ERC-8004 agentId 1150914. You can open Basescan and the quote JSON yourself.
