💰 Paid API A2A 1.0 v1.0.0

api.nohumans.directory

api.nohumans.directory · api.nohumans.directory

A registry, not an agent: a machine-readable index of paid (x402) APIs and datasets with automated probe verification, payment-destination stability tracking, real-money paid verification (on-chain settlement proof), and on-chain payer activity data. Agents consult it before spending money. It performs no tasks and executes no payments on behalf of callers.

partial Valid AgentCard 9/10

AgentCard did not read cleanly: 1 field we could not read. Scored on what we could read, not on a card that arrived as published — the card findings name every affected field and what we did with it.

            How to earn +1 point
          

Publish a parseable A2A AgentCard

Serve a valid AgentCard JSON at /.well-known/agent-card.json. The A2A 1.0 schema is the reference; we accept the v0.x backwards-compatible variant too.

Docs →

partial Live JSON-RPC 15/25

Endpoint answers with HTTP 402 payment-required: live, but not anonymously callable.

            How to earn +10 points
          

Respond live on JSON-RPC

Implement SendMessage for v1.0 (or message/send for v0.x), negotiate A2A-Version, and return a schema-valid JSON-RPC response. Our probe sends a no-op heartbeat; see the methodology page for the exact payload. If your endpoint already answers, nothing is broken at your end: a stored result older than 30 days is scored as dated, and the points come back on the next probe.

partial Protocol version 8/10

Declares A2A 1.0 but missing supportedInterfaces[] (required in v1.0, update your card to reach 10/10).

            How to earn +2 points
          

Declare protocolVersion

Add `"protocolVersion": "1.0"` to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.

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.

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.
