List data blocks (latest version of each)
const url = 'https://example.com/v1/blocks?limit=25&kind=prompt&scopeKind=tenant&includeRetired=false';const options = {method: 'GET', headers: {Authorization: 'Bearer <token>'}};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request GET \ --url 'https://example.com/v1/blocks?limit=25&kind=prompt&scopeKind=tenant&includeRetired=false' \ --header 'Authorization: Bearer <token>'Cursor-paginated. Only the blocks of projects the caller can read. ?kind= narrows to prompts or settings, ?name= is a prefix match on the id, and ?scopeKind= + ?scopeId= narrow to a project or an org, as the other lists do. A retired block (every version unregistered) is listed only with ?includeRetired=true, as its highest version with unregisteredAt, so it can be found and a version reinstated.
Authorizations
Section titled “Authorizations”Parameters
Section titled “Parameters”Query Parameters
Section titled “Query Parameters”1..100. Default 25.
Where the previous page ended: its nextCursor, as it came. A runtime that seals cursors takes one only for the same list, filters and caller, within a day; otherwise 400 bad-input, and the list starts again without it. Absent → first page.
prompt: a Liquid template an agent renders as its instructions. settings: a JSON object tools and templates read.
Only blocks of this kind: prompt or settings.
Prefix match on the block id.
Discriminator for the ?scopeKind + ?scopeId + ?inherit triplet. Tenant carries no id (implicit from session); org/project require scopeId.
Optional scope discriminator. If absent, no scope filter is applied.
Required IF scopeKind is org or project. MUST be absent if scopeKind=tenant (the workspace is implicit from the session). Malformed combinations return 400 scope-invalid.
When true, retired items (every version unregistered) are listed too, each as its highest version with that version’s unregisteredAt. Default: false (items with an active version only).
Responses
Section titled “Responses”Page of blocks.
object
A data block version: a prompt or settings, versioned like a tool (immutable versions, soft unregister). An agent version pins the block versions it uses when it is published. Belongs to one project and is authorized through it.
object
Dotted lowercase id (e.g. acme.intake-prompt).
prompt: a Liquid template an agent renders as its instructions. settings: a JSON object tools and templates read.
object
Liquid, rendered as an agent’s instructions are (same parameters and auto-injected variables).
object
Default value used when the caller omits this parameter.
object
What tools read (ToolContext.settings[<block id>]) and templates read (settings.<block id>.<key>).
object
JSON Schema (draft 2020-12) the values must satisfy. A later version’s values must satisfy the latest version’s schema too.
object
Present only on an unregistered version; agent versions that pin it still read it. A retired block (every version unregistered) carries it as GET /v1/blocks?includeRetired=true lists it.
Who published the version: a user, or a service token. Absent on a version published before it was recorded.
object
Where a block version came from: api (POST /v1/blocks), deploy (a deploy’s pack; id is the deployment’s) or suggested-change (id is the suggested change’s). Absent on a version published before it was recorded.
object
Present for deploy and suggested-change.
