Check being updated

We’re updating how our daily check calls this listing’s example endpoint, so its measured numbers are hidden until the updated check has enough data.

Trust score: coming soon, after 7+ days of data (from about Nov 3).

How we measure: one unpaid check per day of the listing’s example endpoint (GET https://obol.danieldutoit.net/v1/base/network-status). We never pay and never send a payment header. Up means any answer below HTTP 500 except 404/410 within 8 seconds. Uptime counts those daily checks. Payment never changes these numbers. A technical check, not an endorsement. Raw JSON · schema

How we verified it

Submitted via our free basic listing form (CRM 114898, 2026-10-27). Unpaid GET /v1/base/address-snapshot?address=0x1111…1111 returned HTTP 402 on 2026-10-30 with x402 v2 payment terms: exact, 0.001 USDC on Base. The earlier example, /v1/base/network-status (402 on 2026-10-28), now returns 404 and is not in the provider's /.well-known/x402, which lists address-snapshot with this example URL. The provider's /.well-known/x402 (2026-10-28) lists 23 paid resources (22 lookups) at 0.001 to 0.01 USDC, all on Base. Official site, llms.txt and OpenAPI fetched (HTTP 200) on 2026-10-28. Nothing paid. Last checked 2026-10-30.
