C
Conformance score: 60/100
Catalogue listing, not an A2A agent: a paid API listed by agentic.market. Scored on the 3 criteria that apply (24 of 40 points, scaled to 100); the A2A card criteria do not apply.
click to expand breakdown click to collapse breakdown
n/a Agent card n/a
Not applicable: a paid API listed by agentic.market. The host serves no A2A agent card at /.well-known/agent-card.json, so the card criteria are not scored.
partial Live endpoint 15/25
Our probe received an HTTP 402 payment challenge from the host: live, but paid.
n/a Protocol version n/a
Not applicable: no A2A agent card served.
n/a JWS signature n/a
Not applicable: no A2A agent card served.
n/a Uptime track record n/a
Not applicable: our probes looked for an A2A agent card, which this host does not serve. That says nothing about the API's availability, so it is not graded.
n/a Skill declaration n/a
Not applicable: no A2A agent card served.
partial Verified Identity 5/10
Provider declared: base.kagurazaka.dev (https://base.kagurazaka.dev). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.

USDC inflows on Base. Reproducible via eth_getLogs on USDC Transfer events to the wallet. Inflow to a wallet, not proof that every transfer was a paid call.
How the last 30 days were settled
x402-settled: $0.01 (0%) · 4 transfers sent by a known x402 facilitator (Coinbase)
Other: $0.00 plain transfers sent by the payer · $8.90 other contract calls · 92% of $9.66 classified so far. How we classify
Cross-check: Coinbase's Bazaar reports 273 calls in 30 days to this wallet across 140 listed resources; our ledger observed 298 transfers (1 facilitator-settled) over 15 of 30 scanned days. Different counters; neither is assumed correct.
Payment authenticity evidence confidence How we measure this →

2 evidence caveats
shared_settlement_wallet — The settlement wallet is shared with other indexed agents, so inflow cannot be attributed to this agent alone.
Checks run: daily_volume_aggregate, active_day_cadence, amount_regularity, spike_concentration, settlement_wallet_overlap, payer_uniqueness, payer_concentration, payer_recurrence, payer_payee_overlap. Derived from agent_revenue_daily, agents.payment_wallet, agent_payment_transactions. Measured 2026-10-26.
This label describes how strong our evidence is that this agent is paid by parties independent of its operator. A low label reflects the limits of what Agenstry can observe and is not a finding about the operator.
Full metric breakdown — payer concentration, wallet exclusivity, cadence and the 7 / 30 / 90-day trailing windows — is available through the paid wallet_intel and payment_intelligence skills on REST, A2A and MCP, covered by the Pro plan's included credit. API docs →
