Loop XXI

Public data, free to use

Agent payments, counted daily.

A dated record of the endpoints that sell to software agents, how many answer, and the paid traffic one public proxy observes.

For developers comparing payment rails, researchers checking a claim, and buyers who want a number with a date on it instead of a market-size estimate.

Supply by protocol

402index lists endpoints by protocol and probes their health. The counts below are its directory totals for the snapshot day.

A listing is a directory entry, not proof that an endpoint sells or settles. Health is 402index's own probe result; its categories may not add up to the listed total.

Observed demand

l402.space reports cumulative totals for payments routed through its proxy. It sees only those payments, so these numbers are a floor. Agents that pay endpoints directly are not counted.

Other networks groups every non-Lightning network the source reports. The JSON download groups them as other too. Counts are unchanged.

Snapshot history

One row per snapshot day, oldest first. The table shows the last 14 days in the current summary file. Demand columns are cumulative totals reported on that day, not that day's new traffic.

What this is, and what it is not

This is a dated record of public supply and demand signals in agent payments. Loop XXI publishes it because we build payment infrastructure and wanted supply and demand side by side. The sources do the measuring.

It is not Loop XXI revenue, not a market-size estimate, and not investment advice. A number here describes the sources' view of one day, not the size of a market.

Caveats

  • Demand is cumulative and is a floor. l402.space reports totals for traffic through its proxy; direct payments are invisible.
  • Health is someone else's probe. The definitions and thresholds belong to 402index.
  • A listed endpoint may be down, mispriced, or no longer selling.
  • A missing day is missing. The snapshot job does not estimate or interpolate.
  • Sources can change their APIs or definitions. Compare dates, not just totals.
