US bank web census · fetched 2026-09-30

Terms

What this is

An independent, dated measurement of public web properties (4,123 banks), made by fetching each site's public pages and well-known files once and, for a rotating slice, again every six hours. It reports what a site publishes; it is not legal advice, not a security audit and not an endorsement of any site or listing.

Data licence

Census data (pages, JSON records, CSV, NDJSON, feeds) is licensed CC BY 4.0; cite "Agent Exchange US bank web census 2026-09" with a link. Measurement errors happen: a site that blocks our one polite request shows as unreachable or inconclusive, and rules are heuristics described on the report page. Corrections: use the live re-check or the feed for a domain to see the current state.

Paid routes

Payments are made with the x402 protocol in USDC on Base to 0xc91cE6291eDC0713ec753BAFBA002506ffb2b95c and settled by a third-party facilitator; settlement is final and there are no accounts, subscriptions or refunds. A listing runs 30 days from settlement, shows the name, URL and description you sent (placeholder hosts are shown unlinked as test listings), carries rel="sponsored" and may be removed if it is unlawful, deceptive or malicious, without refund. A live re-check returns whatever the checked site answered at that moment. A gap list download returns the file computed from the 2026-09-30 census (CC BY 4.0 data filtered to the banks missing one control); the same facts are in the free dumps and the first 50 rows of every list are free. Unpaid requests to paid routes are rate limited (30 per minute per address for listings).

Crawling and use

Automated reading is welcome: robots.txt allows every crawler, JSON records are CORS-open, and feeds are meant for machines. Bulk use of the dumps is preferred over crawling every page. No personal data is collected; the only server-side counters are anonymous per-route request tallies used to order the sitemap.

Operator

Agent Exchange, one operator, one wallet. All properties are listed at network.agentexchange.work; the payment address above is the only one used.
