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 reference (NY11), dated data from the VALLEC EXPORT digest
Commodity indices: soy, corn, cattle and iron ore (dated data)
Affiliate offers radar from Brazilian marketplaces (Mercado Livre, Shopee, Amazon BR)

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):

OpenAPI spec:

Why

Agents that need Brazil market data 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.
