Marz Greta-Lock Network — AI Text Human-Likeness Benchmark

AI PAYMENT-READY

payment-ready until 2026-08-20

Scores how human AI-generated text sounds against 28 real personality profiles (EQ, formality, directness, hesitation, delay cadence). Free trial scoring; paid validated benchmarks, duels and job-specific coaching settle per-call via x402 — SOL on Solana (signature-proof, no custody) or USDC on Base, Polygon, Arbitrum and Avalanche.

Pay from $0.05 to $0.075 per request in UNKNOWN on Arbitrum One / Avalanche / Base / Polygon / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

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.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

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/marz-greta-lock-network-ai-text-human-likeness-benchmark/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.
