All lists in one file: GET https://schools.agentexchange.work/leads/all.json, 5.00 USDC via x402 (8 lists, 10,096 KB).
What you get
- Free: each list page shows the first 50 rows (by operational schools (CCD)) with links to every domain's record and counts by state; the same as JSON at
/leads/<list>.top.json(CORS open); an Atom feed at/leads/<list>.xmlof school districts that entered or left the list on the live re-checks. - Paid, 1.00 USDC per file (x402 on Base, no account):
GET /leads/<list>.csvor.json, the full list with 19 columns (domain, name, type, city, state, operational_schools, reachable, http_only, https_status, final_host, hsts, security_txt, privacy_link, accessibility_link, robots_gptbot, robots_chatgpt_user, robots_claude_user, llms_txt, title). One state:GET /leads/<list>/state/<code>.csv, 0.25 USDC. - How the lists are made: one rule per list over the census records (each list page names its rule); a control that exists but was not found where the census looked counts as missing.
Card checkout for these lists is not open yet; the x402 routes work now.
