A 10-stage per-chain funnel of every ERC-8004 agent registered on
Base (chain_id 8453) and Ethereum mainnet
(chain_id 1), measured on 2026-10-13. Stages flow from
Registered on-chain to Delivered after
payment: each stage is a count of agents that cleared every
preceding one.
Headline, Base: of 23,403 registered agents, 134 emit any payment field in their on-chain metadata or well-known card, 26 return a parseable 402 challenge with a payTo and a positive price, 25 publish a price in the normal range (≤ $1.00 per call), and 10 delivered a real response when we paid them in three dated test-purchase pilots on 2026-10-12 and 2026-10-13.
Headline, Ethereum: of 2,946 registered agents, 7 advertise, 2 publish a parseable price in the normal range, and 0 were paid in this measurement window — no Ethereum ERC-8004 agent cleared the cheapest-cost gate before the pilot windows closed.
Stages 1-7 are deterministic from the live profile store (every
registered agent is counted). Stages 8-10 are observed: numerators
come from the pilot evidence files
(0982b, 0983, 0988),
denominators are the number of distinct agents in today's stage-7
pool that the pilots attempted. The six Base deliveries that fall
outside today's deterministic stage-7 pool (Convert Guru + five
0988-era agents) are counted separately as
observed_outside_pool: their deliveries are real and
dated, but the price lives on an endpoint our profile store does
not yet persist in live_endpoints.x402_challenge.accepts[].
This dataset is a tracked measurement, not a methodology
change. Readiness/Trust scoring, bucket thresholds, and
the published scoring rules are unchanged by this snapshot. The
funnel will be snapshotted daily going forward
(metrics/payability-funnel/<date>/funnel.json);
new rows will land under
/data/payability-funnel-<date>/.
