AGENT ECONOMY / 01

A price your software can understand.

Metr turns paid access into a session object. The buyer sees the rate, authorizes a maximum, receives the service, and pays only while the meter is active.

CAPABILITY MAP04 SYSTEM PRIMITIVES
01DISCOVER

Machine-readable pricing

Return the price, supported rail, and authorization requirements before access begins.

02CONTROL

Hard spending limits

Let an agent approve a maximum amount before it can consume a paid service.

LOG

Signed session trail

Keep a readable history of the request, authorization, elapsed time, and settlement.

WORKFLOW / 02

THE SYSTEM
IN MOTION.

Each stage has a visible input, an explicit state, and a result the next stage can verify.

  1. 01
    Discover

    The buyer agent asks a service for price and payment requirements.

    GET /rate
  2. 02
    Authorize

    The agent funds or selects a prepaid balance and defines its limit.

    cap = 5 USDC
  3. 03
    Consume

    The service runs while session-state updates record that work is still active.

    status = active
  4. 04
    Settle

    The meter closes and records the final usage charge.

    status = settled

VISIBLE EVIDENCE / 03

MAKE THE STATE
READABLE.

Product activity should leave a trace a developer, operator, or customer can understand. The showcase uses realistic sample data where a live feed is not connected.
