What we found when we checked every ERC-8004 agent on xlayer
10,723 agents|block 67,576,783|run ab6e134c|no score, no ranking, no per-agent aggregate
0148.8%
of valid registration documents declare no way to reach the agent — no services entry at all, or one with nothing in it.
5,067 / 10,390 documents that parsed and reached check 4 (Follows the spec?)
0299.8%
of conforming documents never say which agent they belong to. The registration entry that would bind a document to its on-chain id is only recommended, so most omit it and check 5 (Claims its identity?) records unclaimed — neither a pass nor a fail.
10,355 / 10,376 documents that passed check 4 (Follows the spec?) (conformant)
0310.7%
have at least one on-chain feedback entry — and those agents are less likely to have a document that resolves than agents with none: 99.7% against 96.6%.
1,149 / 10,723 agents in this run
041
the number of MUST requirements ERC-8004 places on a registration file — and it is conditional, so a document that omits registrations entirely has nothing it must do at all.

Every check, every status
base rates on xlayerPopulation counts, not a score for any one agent. A check’s segments do not sum to the whole population when an earlier failure stopped the pipeline — that gap is drawn as its own “not checked” segment rather than folded into whichever status happens to render widest.

Nothing is sent yet — there is no sending side built, so there is no confirmation email to expect, and you will be asked to confirm before the first report goes anywhere.
