Discover backlinks

discover_backlinks Query a configured owned corpus for bounded candidates with dated evidence. Candidates remain unchecked and coverage stays limited to that corpus. No supplier spending or monitoring enrollment. Requires owned-corpus admission and a loaded corpus; unavailable configurations need an operator change. Import owned exports with import_backlinks while admission is unavailable. Reuse idempotencyKey for retries after configuration or network recovery.

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
`discovery:write`	Writes or admits work

Provider-backed admission requires enabled configuration and available allowance; registration alone does not make retrieval available. Inspect usage and the run’s coverage before interpreting results.

Example request

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

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
`projectId`	string	Required	Identifier of the project returned by its create or list operation. pattern: ”^[a-zA-Z0-9_-]{1,128}$“
`targetKind`	string	Required	Whether target identifies an exact URL or a domain. values: “domain”, “exact_url”
`target`	string	Required	Exact URL or domain to query, interpreted according to targetKind. minLength: 1; maxLength: 4096
`includeSubdomains`	boolean	Required	Include subdomains of the selected domain in this query.
`backlinksStatus`	string	Required	Supplier-reported backlink status filter; this is not Linktrail verification. values: “live”, “lost”, “all”
`excludeInternalBacklinks`	boolean	Required	Exclude supplier rows linking within the queried site.
`pageLimit`	integer	Required	Maximum supplier rows requested per page, within the total row limit. minimum: 1; maximum: 1000
`rowLimit`	integer	Required	Maximum total supplier rows admitted for this discovery run. minimum: 1; maximum: 1000
`idempotencyKey`	string	Required	Caller-generated key reused only for retries of the same operation and arguments in this workspace. pattern: ”^[\x21-\x7e]{1,200}$“

Validation and omitted values

includeSubdomains, backlinksStatus, excludeInternalBacklinks, pageLimit and rowLimit are required explicit choices. Provider and ordering are selected by server configuration, not request fields. Owned-corpus query order is first_seen descending with no authority-rank scale. Supplier fixture order uses rank descending with its provider scale; that fixture branch does not activate hosted supplier admission.

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/discovery/runs`	202	Remaining arguments go in a JSON object body. Supply idempotencyKey as the Idempotency-Key header on this resource route.
