1 thing in this card we could not use
Everything else was indexed. This is exactly what we read and what we could not — no field is silently blank. Fix the card at https://pageproof.alert-crab-1890.chatgpt.site/.well-known/agent.json and the next probe clears this panel.
Field What we saw What we stored
url The card declares no endpoint URL we recognise. A2A v1.0 puts it in supportedInterfaces[].url; v0.x used a top-level url. Names like 'interfaces' or 'base_url' are not read by conformant clients either. dropped — we read the card but cannot list this agent as callable

Conformance score: 22/100
Catalogue listing, not an A2A agent: a paid API listed by x402_list. Scored on the 3 criteria that apply (9 of 40 points, scaled to 100); the A2A card criteria do not apply.

Not applicable: a paid API listed by x402_list. The host serves no A2A agent card at /.well-known/agent-card.json, so the card criteria are not scored.

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.

1 evidence caveat
uniform_amount_cadence — Daily settled amounts repeat identically across days, which is consistent with scheduled or scripted activity as well as with flat-rate demand.
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 2026-10-25.
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 →
