Snapshot as of 2026-06-22T12:22:11Z UTC
Every ERC-8004 ReputationRegistry feedback event on Base + Ethereum
that ties back to a real paid Virtuals ACP job or ERC-8183 hook
contract under the canonical
commerce_backed.py predicate. One row per commerce-
backed feedback event (chain, agent_id,
registry_uri, client_address,
hook_type, score_norm, event coordinates,
created_at) plus an aggregate + per-chain breakdown
that separates the commerce-backed cohort from the endorsement-
noise remainder.

Daily per-chain live-endpoint + placeholder-name snapshot of every
ERC-8004 registration on Base + Ethereum. One row per indexed agent

Daily conformance snapshot of every ERC-8004 registration on Base +

Daily trust-filter cut of the public Coinbase CDP x402 Bazaar
discovery catalog, bucketed by CDP’s own
l30DaysUniquePayers signal. Cohort ladder, payer
histogram, network / category / price / host summaries, and a
delta panel against the previous snapshot.

Measured 2026-09-01 UTC · dated snapshot — refreshes only when the join is re-run
Dated point-in-time join of Base x402 earning demand against the
ERC-8004 reputation footprint on Base. Publishes both the
endpoint-level headline and the publisher-level cut in the same
block so the 26-distinct-pay_to
concentration cannot be dropped from the citation. Per-publisher
dedup cap disclosed on-page.

Snapshot as of 2026-09-07T09:00:55Z UTC
Live per-endpoint price distribution of the public Coinbase CDP x402 Bazaar catalog. Percentile ladder (p10–p99), price-bucket histogram, and top-10 most expensive endpoints — all figures the cheapest USDC-denominated leg per endpoint. Two caveats co-located with the headline (floor-not-census, and cheapest-leg lower bound) so a machine reader cannot quote the median naked.

Series 2026-08-15 → 2026-09-07 (24 UTC days)
Daily UTC time series of the public Coinbase CDP x402 Bazaar catalog:
n_items, n_distinct_hosts,
n_distinct_pay_tos, n_priced,
reported_total, median_price_usdc —
one representative row per calendar day using the LAST ok snapshot
of that day. Answers the question directly (the catalog CHURNS,
it does not ACCUMULATE) and holds the standing
CATALOG ≠ PRICED ≠ EARNING
discipline.

Single-slot snapshot · QuantuLabs 8004-solana port on Solana mainnet
Snapshot census of the QuantuLabs 8004-solana agent-registry program on Solana mainnet — raw registrations, distinct-creator concentration cut (top-1 / top-10 / top-20), URI-prefix histogram, and an OpenClaw-adjacent-string disclosure block co-located with the headline count. Not a claim about resolvable agent cards; URIs were not fetched. ERC-8004 itself is still a Draft EIP on Ethereum — the port is a Solana-native re-implementation.

Random-sample measurement · N=1,200 pooled (600 base + 600 ethereum) · seeded, reproducible
Random-sample measurement of hop H2 (tokenURI
resolve) on the ERC-8004 IdentityRegistry across Base and Ethereum.
Every rate reported with its N and a Wilson 95% CI. Host-concentration
caveat co-located with the headline — one operator dominates
the ethereum ok_json bucket. Reported rates are an
UPPER BOUND on resolvability across all non-empty
tokenURIs (population is the discovery-filtered indexed set).
H2 ≠ H3 — this is the tokenURI-returns-JSON
hop, not the /.well-known/agent-card.json discovery
hop.
