On-chain traction
No on-chain settlement recorded. Unverified = not settled or not yet indexed — never treated as zero.
ERC-8004 agent registry
Not found in the ERC-8004 agent registry. This is the default state — absence is not a negative signal.

Endpoints(4)
Same echo endpoint as test-echo-prod, but settlement is routed through the Coinbase Facilitator instead of self-verified on-chain. Used to validate Coinbase Bazaar discoverability for x402-market listings.
Second cdp-mode listing identical to test-echo-cdp, used to A/B test whether the Bazaar indexer picks up newly-created resources differently from one that has been live for several days.
Third cdp-mode echo listing, created after the v2-spec PaymentPayload.extensions fix. Used to test whether a brand-new resource indexed only with the corrected wire format gets picked up by Bazaar discovery.
Identical to test-echo-cdp-fresh except priced at 0.10 USDC (= 100000 atomic units) instead of 0.01. Used to test the hypothesis that Coinbase Bazaar has an undocumented price floor above $0.01.
