Price follows the work
Reliance is a usage-metered utility. The primary meter is the reliance event: each time a relying agent queries the exchange, verifies a cryptographic proof and acts on it within its configured limits. That event is deliberately priced below a fresh from-source verification, because the issuer has already done the checking and signed for it — the relying agent pays for verified reliance, not for repeating work someone else already stands behind.
Metering the event rather than the seat ties price to autonomous transaction volume. A fleet that relies on many claims pays in proportion to how much reliance it consumes, and a governor can see exactly what was relied upon for each charge.
Three streams, one exchange
Revenue is drawn from three streams that reflect the work each side does. Relying parties pay per reliance event. Issuers pay an issuance fee to publish a signed, scoped, revocable attestation, plus a management subscription covering lifecycle, revocation propagation and evidence retention. Enterprise agreements are quote-based, with the admissible issuers, value thresholds and expiry limits set by the relying-party governor.
None of these depend on speculative claims about full agent autonomy. Each is tied to something observable: an attestation published, a proof verified, a lifecycle managed.
