ERC-8004 Commerce-Backed Reputation — the got-paid cohort on Base + Ethereum

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.

ERC-8004 Chain Liveness — daily per-chain live-endpoint & placeholder-name snapshot

Snapshot as of 2026-09-07T08:09:08.976732+00:00 UTC

Daily per-chain live-endpoint + placeholder-name snapshot of every ERC-8004 registration on Base + Ethereum. One row per indexed agent (chain, agent_id, registry_uri, endpoint_url, endpoint_status, is_live, is_placeholder_name, checked_at) plus an aggregate + per-chain breakdown. Independently corroborated by arXiv:2606.26028 (Imperial College, CC BY 4.0).

ERC-8004 → agent-card Signpost Gap — daily conformance snapshot

Snapshot as of 2026-09-07T08:09:08.976732+00:00 UTC

Daily conformance snapshot of every ERC-8004 registration on Base + Ethereum against the A2A /.well-known/agent-card.json signpost. One row per indexed agent (chain, agent_id, registry_uri, endpoint_url, endpoint_status, has_agent_card, checked_at) plus an aggregate + per-chain breakdown.

x402 Bazaar Market Map — daily trust-filter snapshot

Snapshot as of 2026-09-07T09:00:55Z UTC

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.

x402 Paid-But-Unrated — Base earning endpoints × ERC-8004 reputation join

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.

What does an x402 API call cost? — Live price census of the Coinbase CDP x402 Bazaar (USDC, cheapest leg per endpoint)

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.

Is the x402 market growing? — Daily catalog time series of the public Coinbase CDP x402 Bazaar

Series 2026-08-152026-09-07 (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.

Solana agent registry census — raw registrations, creator concentration, and OpenClaw-adjacent disclosure (QuantuLabs 8004-solana port)

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.

ERC-8004 tokenURI resolvability (hop H2) — random sample, per-chain and pooled, Wilson 95% CIs

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.
