How this service works
Bind declared consent to action purpose, scope and expiry
Output
Returns a verifiable consent binding object that records the declared purpose, permitted scope, and expiry timestamp, confirming that consent is formally attached to a specific action and cannot be generalized beyond its stated bounds.
Example use cases
Time-limited consent for financial action
“I'm allowing the agent to initiate a wire transfer on my behalf, but I want that consent locked to just this one transfer purpose and expired after 10 minutes — can you create a purpose-bound consent record for that?”
Scoped consent for sensitive data access
“Before the agent reads my medical records, bind my consent strictly to the 'read health summary' purpose with a 30-minute expiry, so it can't be used to access anything else.”
Audit-ready consent for regulated workflow
“We need to prove that user consent for this GDPR data export was properly scoped to the export purpose only and had a defined expiry — create a bound consent record for compliance audit.”
Technical details
Endpoint
POSThttps://phion.systems/v1/paid/trust/purpose-bound-consentWhen to prefer
Choose this endpoint when an agent needs to enforce that consent is strictly scoped to a declared purpose and time window — particularly for regulated workflows, financial actions, health data access, or any scenario requiring an auditable consent record. Prefer it over generic authentication or authorization checks when the key requirement is purpose-limitation and expiry, not just identity verification.
Side effects
- Missing or malformed purpose declaration results in binding rejection
- Expiry timestamp in the past causes validation failure
- Scope definition too broad or ambiguous may be rejected by policy
- Malformed JSON body returns 400 bad request
- Expired or invalid payment token causes 402 payment required
- Duplicate consent binding attempts may be rejected if already active
