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: x402-api.aubr.ai (https://x402-api.aubr.ai). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.

Cross-check: Coinbase's Bazaar reports 1,838 calls in 30 days to this wallet across 5 listed resources; our ledger observed 1,825 transfers (34 facilitator-settled) over 29 of 30 scanned days. Different counters; neither is assumed correct.

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 2026-10-17.
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 →
