AgentLair

AI PAYMENT-READY

payment-ready until 2026-08-20

AgentLair is identity, trust, and infrastructure for AI agents. Anonymous x402-payable endpoints: pay 0.001 USDC for an A2A AgentCard trust audit, 0.005 USDC to resolve an agent handle to its DID + JWKS, 0.01 USDC to query a trust score, or 0.0001 USDC to submit behavioral events. No API key required — payment is authentication.

Pay from $0.0001 to $0.01 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

ASSESSMENT

updated 3h ago

Evidence-backed signals, not a single score. Click any chip for the proof. Measured values stay read-only; unknown is honest.

reliability 100%

uptime 24h: 100%
uptime 7d: 100%
uptime 30d: 100%
uptime 90d: 100%
response p95: 1006ms
avg response: 277ms
total checks: 2,737

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance A (13/14): x402 v2 envelope delivered in the payment-required header

13 of 14 x402 conformance checks pass; failing: x402 v2 envelope delivered in the payment-required header. Full checklist below.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Attributed pro-quota: this payout address is shared, so volume is the operator-level figure divided by the services sharing it, while buyer and transaction counts stay whole. A declared convention, not an individually observed measure, and still a conservative undercount.

Currently sharing this payout address with AEO Audit API.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/agentlair/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.

price percentile in AI

site signals present (of 6)

Measured site and economics pillars from the assessment history, so the latest value shown elsewhere on this page reads as a point on a trend rather than a permanent state.

VOLUME (on-chain settlement, USD)

Shared payout address (1 other service). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service figure is attributed, the assessment block and the ranking, it is the address total divided pro-quota by the 2 services sharing it: a declared convention, not an individually observed measure.

DISTINCT BUYERS

Shared payout address (1 other service). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Per-service buyer and transaction counts are shown whole (integers), not divided; only volume is attributed pro-quota. A declared convention, not an individually observed measure.
