F

Conformance score: 22/100

Catalogue listing, not an A2A agent: a paid API listed by cdp_discovery. Scored on the 3 criteria that apply (9 of 40 points, scaled to 100); the A2A card criteria do not apply.

n/a Agent card n/a

Not applicable: a paid API listed by cdp_discovery. The host serves no A2A agent card at /.well-known/agent-card.json, so the card criteria are not scored.

fail Live endpoint 0/25

No response from the host observed: listed by cdp_discovery only, not confirmed by our own probe.

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: wren-guard-pro.wrenonbase.workers.dev (https://wren-guard-pro.wrenonbase.workers.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

$0.18 in the ledger, not classified yet. Each transfer is read once to tell facilitator-settled x402 payments from plain transfers. How we classify

Cross-check: Coinbase's Bazaar reports 9 calls in 30 days to this wallet across 3 listed resources; our ledger observed 9 transfers (0 facilitator-settled) over 29 of 30 scanned days. Different counters; neither is assumed correct.

3 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 2026-10-22.

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 →
