Request target check

request_target_check Queue a metered destination health check. Reuse the idempotency key for a retry; blocked results remain unknown.

Hosted MCP registration verified. These schemas describe the development contract; confirm supported inputs with tools/list. Generic CLI/HTTP calls require a matching development server. Configure LINKTRAIL_API_URL; production does not expose these command routes.

Access	Behavior
`watches:write`	Writes or admits work

Checks and monitoring can consume workspace capacity. Queued admission is not a completed observation; inspect the returned job or saved state.

Example request

Connect through MCP, CLI, or HTTP. Replace example identifiers with records from your workspace.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "request_target_check",
    "arguments": {
      "targetId": "target_example",
      "idempotencyKey": "docs-request-001"
    }
  }
}

linktrail call request_target_check --args '{"targetId":"target_example","idempotencyKey":"docs-request-001"}'

curl "$LINKTRAIL_API_URL/v1/commands/request_target_check" \
  -H "Authorization: Bearer $LINKTRAIL_API_KEY" \
  -H 'Content-Type: application/json' \
  --data '{"targetId":"target_example","idempotencyKey":"docs-request-001"}'

Returned result

Illustrative data validated against the documented response schema. IDs and dates are examples, not a live account capture. MCP returns this data in structuredContent and in a text content block; generic HTTP and CLI return the JSON result directly.

Input fields

Omit optional fields when you do not want to supply them. Null is accepted only where listed. Unknown input properties are rejected.

Field	Type	Presence	Meaning and constraints
`targetId`	string	Required	Identifier of the target returned by its create or list operation. minLength: 1; maxLength: 200
`idempotencyKey`	string	Required	Caller-generated key reused only for retries of the same operation and arguments in this workspace. minLength: 1; maxLength: 200

Validation and omitted values

Save the returned job identifier and read get_target_job. Destination jobs and evidence are independent of source-link presence. Reuse the original idempotencyKey after a lost response. A paused or already-busy destination needs its current state inspected before new admission.

Output fields

Fields inside optional or nullable parents apply only when that parent exists. Common schema conventions explain evidence states, empty lists and extensions.

Field	Type	Presence	Meaning and constraints

`state`	string	Required	Saved lifecycle or evidence state, as enumerated for this record. values: “queued”, “running”, “succeeded”, “failed”, “cancelled”
`workspace_id`	string	Required	Workspace that owns this record.
`project_id`	string	Required	Project that owns this record.
`watch_id`	string	Optional	watch id recorded for this result.
`target_id`	string	Optional	target id recorded for this result.
`type`	string	Optional	type recorded for this result.
`execution_mode`	string	Optional	execution mode recorded for this result.
`idempotency_key`	string	Required	Caller retry identifier, bound to the original request arguments.
`payload_hash`	string	Required	payload hash recorded for this result.
`attempt_count`	number	Required	attempt count recorded for this result.
`max_attempts`	number	Required	max attempts recorded for this result.
`lease_token`	string / null	Required	lease token recorded for this result.
`lease_expires_at`	string / null	Required	lease expires at recorded for this result.
`error_code`	string / null	Required	error code recorded for this result.
`error_message`	string / null	Optional	error message recorded for this result.
`created_at`	string	Required	UTC timestamp when the record was created.
`updated_at`	string	Required	UTC timestamp of the last record update.
`completed_at`	string / null	Required	completed at recorded for this result.
`replayed`	boolean	Optional	True when the response reuses an earlier request with the same idempotency value.
`usage`	object / null	Optional	usage recorded for this result.
`usage.units`	number	Required	units recorded for this result.
`usage.state`	string	Required	Saved lifecycle or evidence state, as enumerated for this record.

Errors and retries

The command is annotated idempotent. Reuse an accepted idempotency key when the input provides one; changing the payload under a reused key can conflict. See error recovery for status, scope, cooldown, cursor and retry handling. Unknown observations are result data and do not establish loss.

HTTP resource routes

These existing resource routes share the operation’s domain behavior. Their parameter placement, status and response envelope can differ from generic invocation. See HTTP route details.

Method and route	Success	Details
`POST /v1/targets/{targetId}/recheck`	202	Remaining arguments go in a JSON object body. Supply idempotencyKey as the Idempotency-Key header on this resource route.
