C

Conformance score: 60/100

Catalogue listing, not an A2A agent: a paid API listed by x402_list. 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 x402_list. 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: gateway.nanotab.dev (https://gateway.nanotab.dev). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.

single_day_concentration — Most observed volume landed on a single day of the window.

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 2026-11-04.

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 →
