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://topagentx402.vercel.app/.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

F

Conformance score: 22/100

Catalogue listing, not an A2A agent: a paid API listed by agentic.market. 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 agentic.market. 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 agentic.market 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.

1 evidence caveat

short_observation_window — Fewer than three active days observed — too little history to characterise a pattern.

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 →
