LupaPlaza: A Live Index of Payable LatAm Endpoints

lupaplaza.com Observed source

Editorial interest 82/100 Selection signal · not a rating of the site

A public directory of LatAm data endpoints that accept x402 payments on Base mainnet and return their data.

Landing page captured for the 2026-09-05 issue.

Field notes

The index exposes a small, machine-oriented catalog rather than a general API marketplace: current entries are filtered to HTTP 402 resources on Base mainnet and can be sorted by price or recency. Listings include concrete settlement evidence, with per-request prices from $0.005 to $0.05 USDC. The visible catalog leans heavily toward Argentine financial data, including BCRA policy rates, VAT rules, foreign-exchange quotes, and a narrowly scoped Mobbex fee slice.
