How this service works
Compare quote revisions for price, asset, payee, resource and expiry changes in an exact offer/network frame. No automatic acceptance of price changes or new payment signatures. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.
Output
Returns a structured delta map highlighting field-level differences between two payment quote revisions, covering price, asset, payee, resource, and expiry changes. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days. No payment signatures are auto-accepted.
Example use cases
Detecting unauthorized quote price changes
“I received two versions of a payment quote and I want to know if the price or asset changed between them — can you diff the before and after objects and flag any discrepancies? Use public data class and non-personal metadata only.”
Auditing payee or resource modifications
“Check whether the payee or resource fields changed between the original quote revision and the updated one I have — I need a structured delta map showing exactly what's different, using synthetic data class with non-personal metadata.”
Verifying quote expiry tampering
“I need to confirm whether the expiry on this payment quote was altered between two revisions. Please compare the before and after quote objects and report any changes to the expiry, price, or asset fields using non-personal metadata only.”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/verify/payment-quotes/revision-delta-map?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an exact, deterministic field-level comparison between two revisions of a payment quote and want to detect changes in price, asset, payee, resource, or expiry without any automatic acceptance of new terms. Prefer this over generic diff tools when working within an x402 payment context and requiring offline, typed, non-personal metadata guarantees with defined result retention periods.
Side effects
- Missing or malformed 'before' or 'after' objects returns a validation error
- dataClass not set to 'public' or 'synthetic' causes a schema rejection
- nonpersonalMetadata must be explicitly set to true; any other value is rejected
- Supplying personally identifiable data in metadata fields may result in rejection
- Quote objects with unsupported field structures may produce incomplete delta maps
