I put Brazil agribusiness data behind x402: AI agents pay $0.05 USDC per call

I run VALLEC EXPORT, an agribusiness export desk in Brazil. I just put our market data behind the x402 payment protocol so AI agents can buy it directly, no accounts or API keys needed.

What the API sells

• ICUMSA 45 sugar price index
• Agri commodity indices
• Affiliate offers radar for agri products

How it works

Agents pay $0.05 in USDC per call. It settles on Base, Polygon, Arbitrum, Avalanche or Monad. The API follows the x402 spec: request, 402 response, payment, data.

Public revenue dashboard (updates live, test-network rows are labeled TESTE and excluded from totals):

Why

Agents that trade, research or source agri products in Brazil currently scrape or subscribe. Per-call USDC payment seemed like the right primitive for machine buyers, so I wired it to the data we already produce.

Happy to answer questions. It is early: revenue so far is zero, and I will keep the dashboard public either way.
