x402 APIPassing, checked 58 min ago

Use to size competing or neighboring construction around one Rio Grande Valley address before you buy, lend, lease or build there: count, summed filed cost and each commercial project within radius_mi (default 1, max 5), nearest first. Hidalgo, Cameron, Starr and Willacy counties; about 68% of filings have a map point. An address we cannot place is a free 404. Example: "How many commercial projects were filed within two miles of 1201 E Capote Central Ave, Pharr, and what are they worth?"

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.03.
