Intelligence for the machine economy.
Machine Observer tracks how autonomous software discovers services, spends money, builds trust, accesses data, and interacts with digital and physical markets. Explore independent indexes, research and machine-readable data built from traceable evidence.
Observe. Analyze. Act.
Start with the public record, move into evidence-backed analysis, then use machine-readable interfaces when software needs to act on the information.
24 component metrics from 8 source families. Baseline 100 = the first seven stored observations. Methodology
Headline signals
The smallest set of measurements that explains what is changing now.
Average Settled Transaction
derived meanDerived: cumulative settled USD ÷ cumulative transactions. A cumulative arithmetic mean over the entire measured history of the rail. It is not the median transaction, and it is not the value of a recent transaction. Source: Agent Economy · refresh daily.
Average Settled Transaction: $0.218 USD, from 34 observations. Derived: cumulative settled USD ÷ cumulative transactions. A cumulative arithmetic mean over the entire measured history of the rail. It is not the median transaction, and it is not the value of a recent transaction. Source: Agent Economy · refresh daily.x402 Transactions / Day
rateDerived: (transactions at t − transactions at t−1) ÷ days between observations. Interval-normalized so observations spaced differently remain comparable. Intervals shorter than about five hours are skipped rather than extrapolated. Source: Agent Economy · refresh daily.
x402 Transactions / Day: 5,769 transactions/day, from 32 observations. Derived: (transactions at t − transactions at t−1) ÷ days between observations.

AI Regulatory Activity
Observed changes to AI policy instruments, by the day Machine Observer saw them
320 observed change events across 11 observation days. Regulatory activity rising is neither good nor bad news; it is movement.
Bucketed by the day Machine Observer observed the change, which is the only date it can attest to.
