List API Keys
Returns a page of the caller’s own non-revoked API keys. Choose the initial page with limit, sort, and order. When next_page_url is non-null, follow that relative URL unchanged to retrieve the next page; it preserves the effective query and carries the opaque cursor. Requires the keys scope.
GET
/api_keysAuthorization
UDX-Access-KeyAPI key · headerrequiredOpaque API key ID.
UDX-Access-TimestampAPI key · headerrequiredUnix time in milliseconds, within 30 seconds of server time.
UDX-Access-SignatureAPI key · headerrequiredStandard-base64 RSA-PSS/SHA-256 signature with a 32-byte salt. Sign `timestamp + METHOD + path`; for requests with a body, append `hex(SHA256(body))`; append `UDX-Idempotency-Key` when it is present.
or
AuthorizationBearer token (JWT) · headerrequiredBearer token for an active signed-in UDX user.
Query parameters
limitintegerMaximum number of items to return in one page. Defaults to 10 when omitted; must be an integer from 1 to 100. A value outside that range is rejected with 400 rather than silently clamped. A returned next_page_url preserves the effective value.
min 1 · max 100 · default: 10
pagestringOpaque token identifying the requested page. Clients should not construct or extract this value; follow next_page_url from the previous response unchanged instead.
max length 512
sortstringField to sort by. Defaults to created_at. The API key's identifier is always appended as a tie-breaker, so the order is fully deterministic.
default: "created_at"
Allowed:
created_atnameorderstringSort direction. Defaults to desc. Applies to the default sort field when sort is omitted. Nulls sort last in both directions.
default: "desc"
Allowed:
ascdescHeader parameters
UDX-VersionstringDated API version (YYYY-MM-DD). Omit to use the oldest supported version. An unknown version returns `400`.

objectnamestringrequiredThe nickname given to this key at creation.
max length 200
scopesAPIKeyScope[]requiredThe permissions this key was granted at creation. Fixed for its lifetime — a different set of scopes means a new key.
max items 5
account_idstring | nullThe opaque public identifier of the single account this key is restricted to, or null if it's usable against every account accessible to the caller.
created_atstring<date-time>requiredUDX timestamps use RFC 3339; requests require an explicit UTC offset and zero to six fractional digits; responses use UTC with exactly six fractional digits. When this key was created. Keys are immutable, so nothing about it changes after this point except being revoked.
max length 40
next_page_urlNextPageURL | nullrequiredRoot-relative URL for the next page, including the effective limit, sort, order, filters, and opaque cursor. Follow it unchanged with the same authentication. Null when there are no more items. It never contains credentials or an authority/host.

400Request doesn't conform to this spec.
typestring<uri-reference>A stable URI identifying the error's general category. Usually absent (equivalent to "about:blank" per the RFC); documented rate controls use closed URN values so callers can distinguish same-status retry causes without parsing localized prose.
