Measurement Protocol

How it works

Three calibration stages from input to reading.

STAGE 01
Q

Query the service

Enter any domain or call our API. We check our database of calibrated services.

STAGE 02
M

Measure 4 pillars

Contract Clarity, Availability, Response Fidelity, and Identity & Safety. Each precisely weighted.

STAGE 03
R

Read the verdict

HIGH, MEDIUM, LOW, or VERY_LOW. Plus risk flags and maximum transaction recommendation.

Measurement Vectors

What we measure

Six detection vectors feeding into our 4-pillar calibration model.

☵

Wallet Clustering

Detect spam farms by analyzing wallet reuse patterns and clustering across services.

❐

Template Detection

Identify mass-listed clone services using description similarity and metadata fingerprinting.

⚙

Schema Quality

Validate x402 payment schemas for completeness, phantom fields, and contract clarity.

⚠

Mass Listing Flags

Flag services with unusually high endpoint counts from single wallets or domains.

☷

Metadata Quality

Score description quality, pricing consistency, and network configuration accuracy.

⚡

Endpoint Health

Continuous uptime monitoring with latency tracking and timeout detection every 30 minutes.
