Settings
A2A settings control three things for one identity: whether its receiver is reachable at all, who is admitted, and what its Agent Card advertises.
A2A is off by default and available only to claimed identities. Until you enable it, the public card route returns 404 and no peer can send the identity work.
Get A2A settings GET
GET /api/v1/identities/{agent_handle}/a2a/settingsReturns the identity's current A2A configuration plus lifetime task counts. An identity that has never touched A2A returns the defaults — disabled, whitelist, no custom skills — rather than a 404.
Response (200)
JSON| Field | Type | Description |
|---|---|---|
enabled | boolean | Whether the receiver is reachable. false until you turn it on |
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 public 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
cURLUpdate A2A settings PUT
PUT /api/v1/identities/{agent_handle}/a2a/settingsUpdates only the fields you send. Omitted fields keep their current values, so you can flip enabled without restating your skills.
Request body
| Field | Type | Required | Description |
|---|---|---|---|
enabled | boolean | No | true publishes the Agent Card and opens the receiver; false closes it and stops serving the card |
filter_mode | string | No | whitelist or blacklist. Organization administrators only |
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 |
JSONResponse (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 | filter_mode was supplied by a key without organization-administrator authority |
| 404 | No identity with that handle is visible to the caller |
| 422 | The body is invalid — duplicate skill ids, 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.
