Create User Token
Create a short-lived agent token scoped to a specific user.
Requires both an x-sumvin-agent-id header identifying the calling agent
and an x-sumvin-agent-key header containing that agent’s API key. Each
agent has its own credential in the registry — the resulting agent token
is tagged with the calling agent_id for audit and revocation.
Headers
Controls how timestamp fields are serialized in JSON response bodies.
Default (header omitted or any other value): epoch milliseconds as integers.
iso8601: UTC ISO 8601 strings of the form YYYY-MM-DDTHH:MM:SSZ.
Example: with X-Timestamp-Format: iso8601, the field value 1704067200000 becomes "2024-01-01T00:00:00Z".
Affected fields (recursively, in dicts and arrays): any field whose name ends in _at, plus the literal field names timestamp, period_start, and period_end. All other fields are passed through unchanged.
Only iso8601 is recognized. Any other value (or omitting the header) yields the default epoch-ms representation; the server does not reject unknown values, so this is documented as an example rather than an enum to keep generated clients permissive.
