Alby runs a hosted x402 facilitator for Bitcoin Lightning at x402.albylabs.com, built on Nostr Wallet Connect: sellers connect a wallet and the facilitator confirms payment by looking the invoice up, rather than by checking a preimage. On 2026-09-24 its /supported endpoint advertised exact on bip122:000000000019d6689c085ae165831e93, the network id used before the x402 Foundation merged the Lightning spec with the lnbtc namespace on 2026-09-23, so clients built to the merged spec will not match it until it is updated. The repo was last pushed in May 2026.

State changed on 2026-10-30 (responding → failing).
This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden.
Last 30 days — to 2026-11-09, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
