On 2026-10-24, 17 of the 31 x402 facilitators in the archive answered /supported and listed a matrix of chains, schemes and versions. 1 answered without listing a matrix; 13 showed no matrix that day (a key wall or no answer) and are marked not read.
Cards are in alphabetical order of id. They carry no rank and no score. A cell is what the facilitator's own /supported answer listed on its date; it does not say the facilitator settles payments on that chain. A carried cell is the last matrix we saw from a facilitator that did not show one on the day. Incentive calendar read 2026-10-13: it says a program was running on that chain, not that it moved any number.
