Locate link

locate_link Read link occurrences from one saved observation ID. Does not search URLs or fetch the publisher page.

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:read`	Reads saved data

Reading saved data does not start a verification job. Mutations can change saved records or access; the effects below apply.

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": "locate_link",
    "arguments": {
      "observationId": "observation_example"
    }
  }
}

linktrail call locate_link --args '{"observationId":"observation_example"}'

curl "$LINKTRAIL_API_URL/v1/commands/locate_link" \
  -H "Authorization: Bearer $LINKTRAIL_API_KEY" \
  -H 'Content-Type: application/json' \
  --data '{"observationId":"observation_example"}'

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
`observationId`	string	Required	ID of a saved observation; this does not fetch a new publisher page. minLength: 1; maxLength: 200

Validation and omitted values

Reads occurrences from the supplied saved observation. It does not fetch a URL or look up a watch by URL.

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. Operation-specific errors include OBSERVATION_NOT_FOUND, OBSERVATION_UNREADABLE. 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
`GET /v1/observations/{observationId}/locate`	200	Remaining read arguments go in query parameters.
