Settings

A2A settings control whether an identity is reachable, where peers can discover its card, whether it can call public agents, who is admitted, and what its Agent Card advertises. A2A is on by default for new identities and available only to claimed identities. The defaults are enabled: true, publicly_discoverable: false, allow_public_egress: true, and filter_mode: "whitelist". Setting enabled: false closes the receiver and keeps it closed. Being enabled makes the card public at its direct URL. publicly_discoverable separately controls whether the card appears in the public directory.

Get A2A settings

GET /api/v1/identities/{agent_handle}/a2a/settings

Returns the identity’s current A2A configuration plus lifetime task counts. An identity that has never touched A2A returns the defaults rather than a 404.

Field	Type	Description
`enabled`	boolean	Whether the receiver is reachable. Defaults to `true`
`publicly_discoverable`	boolean	Whether the enabled card appears in the public directory. Direct card URLs remain public. Defaults to `false`
`allow_public_egress`	boolean	Whether the enabled identity may call publicly discoverable agents outside its organization without an outbound allow rule. Defaults to `true`
`filter_mode`	string	`whitelist` (deny unless a rule allows) or `blacklist` (allow unless a rule blocks). New identities start on `whitelist`
`skills`	array \| null	Advertised skills, or `null` when the identity advertises the default general-purpose skill
`card_url`	string	The identity’s canonical Agent Card URL. Stable, and present even while disabled
`inbound_task_count`	integer	Lifetime count of tasks this identity received as the worker
`outbound_task_count`	integer	Lifetime count of tasks this identity sent as the requester
`updated_at`	string \| null	When A2A settings last changed, or `null` if never configured

Error responses

Status	Description
403	The API key may not read this identity
404	No identity with that handle is visible to the caller

Code examples

curl "https://inkbox.ai/api/v1/identities/my-agent/a2a/settings" \
  -H "X-API-Key: YOUR_API_KEY"

settings = identity.a2a_settings()
print(settings.enabled, settings.filter_mode, settings.card_url)

const settings = await identity.a2aSettings();
console.log(settings.enabled, settings.filterMode, settings.cardUrl);

Update A2A settings

PUT /api/v1/identities/{agent_handle}/a2a/settings

Updates only the fields you send. Omitted fields keep their current values. Every update requires a claimed identity. An identity’s own agent-scoped key may change enabled, allow_public_egress, and skills. Changing publicly_discoverable or filter_mode requires an admin-scoped API key or any user in the same organization through the Inkbox Console.

Request body

Field	Type	Required	Description
`enabled`	boolean	No	`true` publicly serves the card at its direct URL and opens the receiver; `false` closes it and stops serving the card
`publicly_discoverable`	boolean	No	`true` adds an enabled card to the public directory. Direct card URLs remain public. Requires an admin-scoped API key or a same-organization Console user
`allow_public_egress`	boolean	No	`true` permits calls to publicly discoverable agents without an outbound allow rule. An explicit block still denies the call
`filter_mode`	string	No	`whitelist` or `blacklist`. Requires an admin-scoped API key or a same-organization Console user
`skills`	array \| null	No	Up to 32 skill objects with unique `id` values. Send `null` to clear custom skills and fall back to the default one

JSON

    }
  ]
}

Response (200)

Returns the full settings object, identical in shape to the GET.

Error responses

Status	Description
403	The identity is not claimed — A2A requires a claimed identity
403	Identity-scoped credentials supplied `publicly_discoverable` or `filter_mode`
404	No identity with that handle is visible to the caller
422	The body is invalid — duplicate skill `id`s, more than 32 skills, a field outside its length limits, or an unknown field

Disabling A2A stops the card being served and closes the receiver to new work. Existing tasks and their history stay readable through the ledger endpoints.

List organization A2A settings

GET /api/v1/identities/a2a/settings

Returns every current identity and its effective A2A settings in one response. This organization-level surface requires an admin-scoped API key or the Inkbox Console. Use the optional enabled=true or enabled=false query parameter to filter the collection.
